Answers

Answer:

A.) 6.4 units

Step-by-step explanation:

We can use the Pythagorean theorem to find the length of AB.

If we find the horizontal and vertical distance of A and B, we form a triangle, with leg lengths of 5 and 4.

Now, we just solve using the Pythagorean theorem.

5^2 = 25

4^2 = 16

25 + 16 = 41

sqrt 41 ≈ 6.4 units.

Answers

Answer:

rida22 this is the third of these you asked for...

do you need help on the steps???

the solution is using the Pythagorean    theorem (a^2 + b^2 = c^2)

so distance "A" = x1-x2 which is 4 - (-4) in your problem = 8

[tex]a^2 + b^2 = c^2[/tex]

[tex]8^2 + b^2 = c^2[/tex]

"B" = y1-y2 = -5 - 2 = -7

[tex]8^2 + (-7)^2 = c^2[/tex]

64 + 49 = c^2

c^2 = 113

c = [tex]\sqrt{113}[/tex]

There is a bag with 50 popsicles inside. 5
are red, 15 are orange, 12 are blue, 8 are
yellow and 10 are purple. If you were to
grab one popsicle from the bag, what is
the probability that it is red or not orange?
P(not red)

Answers

Answer:

25%

Step-by-step explanation:

We know that there are ten purple popsicles. Together without the purple popsicles, there are 40 popsicles in total. Therefore there is a 10/40 chance to get purple. We need to turn this into a percentage so we do (10 / 40) x 100. This would equal to 25%, therefore, there is a 25% probability to get a purple popsicle.

Belinda is thinking about buying a house for $179,000. The table below shows the projected value of two different houses for three years:


Number of years 1 2 3
House 1 (value in dollars) 186,160 193,606.40 201,350.66
House 2 (value in dollars) 190,000 201,000 212,000


Part A: What type of function, linear or exponential, can be used to describe the value of each of the houses after a fixed number of years? Explain your answer. (2 points)

Part B: Write one function for each house to describe the value of the house f(x), in dollars, after x years. (4 points)

Part C: Belinda wants to purchase a house that would have the greatest value in 30 years. Will there be any significant difference in the value of either house after 30 years? Explain your answer, and show the value of each house after 30 years. (4 points)

Answers

In this question, two houses have an initial value of $179,000, and the projected values are given in the tables for houses 1 and 2.

Part a:

If the absolute value of the change is always the same, it is linear.

If the rate is the same, it is exponential.

House 1:

We have that:

193,606.4 - 186,160 = 7446.4

201,350.66 - 193,606.40 = 7744.26

Let's try exponential:

[tex]\frac{193,606.4}{186,160} = 1.04[/tex]

[tex]\frac{201,350.66}{193,606.40} = 1.04[/tex]

For house 1, the rate of change is the same, and thus, it is exponential.

House 2:

212,000  - 201,000 = 201,000 - 190,000 = 11,000.

Absolute value of change is the same, so linear.

Thus, for house 1, an exponential function is used, as the rate of change is the same, and for house 2, as the absolute value of change is always the same, it is linear.

Part B

House a:

Exponential function, with initial value of $179,000, and exponential growth rate of 1.04 - 1 = 0.04. Thus:

[tex]f_a(x) = 179000(1+0.04)^x[/tex]

[tex]f_a(x) = 179000(1.04)^x[/tex]

House b:

Linear function, with initial value of $179,000, increasing by $11,000 each year. So

[tex]f_b(x) = 179000 + 11000x[/tex]

Part c:

House a after 30 years:

[tex]f_a(30) = 179000(1.04)^30 = 580,568[/tex]

House b after 30 years:

[tex]f_b(30) = 179000 + 110000(30) = 509,000[/tex]

In 30 years, house a will have a value of $580,568, while house b will have a value of $580,568. House a will have a higher value, due to exponential growth.

Your cellphone plan is by the minute. Each minute of use costs $0.10. Create a relation that represents the amount spent, A, per minute, m, of call time. Then, use the relation to find the amount spent if you talk 65 minutes. Show your work.

Answers

Answer:

A = 0.1m

A = $6.5

Step-by-step explanation:

We are told that each minute of use costs $0.10.

If the minutes spent is represented by "m" and amount spent is "A', then the relation for amount spent is;

A = 0.1m

If he talked for 65 minutes, then we have;

A = 0.1 × 65

A = $6.5

In circle B, given isosceles triangle BTX, BA ⟂ WX, and WX = 10, what is the radius of circle B rounded to the nearest whole number?

Answers

Solution :

We observe that :

[tex]$\overline {BA} \perp \overline {WX}$[/tex]

But BA is the perpendicular.

From the center B and WX is a chord.

Therefore, TW = TX (perpendicular from the centre of a circle to a chord bisects it)

Consider Δ BTX,

∠BTX = 90° (BA ⊥ WX)

BT = XT (Δ BTX is isosceles)

Since the angles opposite to equal sides are equal of a triangle arc are equal.

∠BTX = ∠BXT

But in the triangle,

∠TBX + ∠TXB + ∠BTX = 180°

∠TBX + ∠TBX + 90° = 180°

2 ∠TBX = 90°

∠TBX = 45°

From trigonometry, we get

[tex]$\sin \theta =\frac{TX}{BX}$[/tex]    ...............(1)

WX = 10

i.e., TX + TW = 10

But TX  = TW

     2 TX = 10

         Tx = 5

BX = radius of circle.

∴ [tex]$\sin 45^\circ = \frac{5}{BX}$[/tex]

  [tex]$\frac{1}{\sqrt2} = \frac{5}{BX}$[/tex]

 [tex]$BX = 5\sqrt2$[/tex]

        [tex]$=5 \times 1.41$[/tex]

        = 7

Therefore, the radius of the circle is 7 units.

A group of 17 students participated in a quiz competition. Their scores are shown below:

Score 0–4 5–9 10–14 15–19 20–24
Number of students 4 5 2 3 3
Part A: Would a dot plot, a histogram, or a box plot best represent the data shown above. Explain your answer. (4 points)

Part B: Provide a step-by-step description of how you would create the graph named in Part A. (6 points)

Answers

Part A

Answer: Histogram

Explanation:

A histogram is best because it helps show how the scores breakdown for the various bins or intervals or classes. It's effectively a visual summary of a grouped frequency table.

A dot plot would not work because we don't know the specific scores, but rather just the general region of where they fall.

A box plot doesn't work well either because we lose information on how the distribution is broken down. Sure we get the five number summary out of it, but we don't see how the bins are set up.

============================================================

Part B

We have the categories or bins of 0-4, 5-9, 10-14, 15-19, 20-24. Each bin will correspond to a bar that tells us how frequently the values show up. It tells us how frequent or how many scores we got in that sub-interval.

The bin 0-4 has a bar that is 4 units high which means we got 4 scores that are between 0 and 4The bin 5-9 has a bar that is 5 units high, so we have 5 scores between 5 and 9.The bin 10-14 has a bar that is 2 units high since we have 2 scores in this region.

And so on. This all leads to the histogram shown below.

Answer:

Part A is a histogram.

Part B draw a histogram

Step-by-step explanation:

This is because a dot plot and a box plot are too specific for how the data was given. We don't know the exact number for each student.

Part B The x axis would be labeled by the groups, 0-4, 5-9, 10-14, 15-19, 20-24. The y axis would be labeled number of students. Then you could color in the area matching the correct number of students for each category.

On a job application, Doris gave her age as 32 years. Her actual age at the time was about 27.What is the relative error for her age?

Answers

Answer:

18.52%

Step-by-step explanation:

Relative error can be described as the ratio of the measured absolute value to the actual value

relative error = (stated age - actual age) / actual age x 100

(32 - 27) / 27 x 100

5 / 27 x 100 = 18.52%

Dave is a builder. Yesterday he made mortar mix. He used 24kg of sand and 5kg of cement. Today he needs to make the same type of mortar mix, but he will use 36kg of sand. How much cement does he need?

Answers

Answer:

7.5 kg

Step-by-step explanation:

Ratio of sand to cement = 24kg : 5kg

Today he needs to make the same type of mortar mix, but he will use 36kg of sand.

Let

x = quantity of cement used

Ratio of sand to cement = 36 kg : x kg

Equate both ratios

24 kg : 5 kg = 36 kg : x kg

24/5 = 36/x

Cross product

24 * x = 5 * 36

24x = 180

x = 180/24

x = 7.5

x = quantity of cement used = 7.5 kg

what must be added to x3-3x2-12x+19 so that the result is exactly divisible by x2+x-6?

Answers

Answer:

[tex]x^3-3x^2-12x+19[/tex] is divisible by [tex]x^2+x-6[/tex]  when [tex]2x+5[/tex] is added to it.

Step-by-step explanation:

Let [tex]p(x)=x^3-3x^2-12+19[/tex]  &  [tex]q(x)=x^2+x-6[/tex]

By division algorithm, when p(x) is divided by q(x), the remainder is a linear expression in x

So, let [tex]r(x)=ax+b[/tex] is added to [tex]p(x)[/tex] so that [tex]p(x)+r(x)[/tex] is divisible by [tex]q(x)[/tex]

Let, [tex]f(x)=p(x)+r(x)[/tex]

⇒ [tex]f(x)=x^3-3x^2-12x+19+ax+b[/tex]

[tex]f(x)=x^3-3x^2+x(a-12)+b+19[/tex]

We have,

[tex]q(x)=x^2+x-6=(x+3)(x-3)[/tex]

Clearly, [tex]q(x)[/tex] is divisible by [tex](x-2)[/tex] and [tex](x+3)[/tex]

{ [tex](x-2)[/tex] and [tex](x+3)[/tex] are factors of [tex]q(x)[/tex] }

We have,

[tex]f(x)[/tex] is divisible by [tex]q(x)[/tex]

⇒ [tex](x-2)[/tex] and [tex](x+3)[/tex] are factors of [tex]f(x)[/tex]

From factors theorem,

If [tex](x-2)[/tex] and [tex](x+3)[/tex] are factors of [tex]f(x)[/tex]

then [tex]f(2)=0[/tex] and [tex]f(-3)=0[/tex] respectively,

⇒ [tex]f(2)=0[/tex] ⇒ [tex]2^3-3(2)^2+2(a-12)+b+19=0[/tex]

⇒ [tex]8-12+2a-24+b+19=0[/tex]

⇒ [tex]2a+b-9=0[/tex]

Similarly,

[tex]f(-3)=0[/tex] ⇒ [tex](-3)^3-3(-3)^2+(-3)(a-12)+b+19=0[/tex]

⇒ [tex]-27-27-3a+36+b+19=0[/tex]

⇒ [tex]b-3a+1=0[/tex]

Subtract (1) from (2)

[tex]b-3a+1-(2a+b-9)=0-0[/tex]

⇒ [tex]b-3a+1-2a-6+9=0[/tex]

⇒ [tex]-5a+10=0[/tex] ⇒ [tex]5a=10[/tex] ⇒ [tex]a=2[/tex]

Put [tex]a=2[/tex] in equation 2

⇒ [tex]b-3[/tex] × [tex]2+1=0[/tex] ⇒ [tex]b-6+1=0[/tex] ⇒ [tex]b-5=0[/tex] ⇒ [tex]b=5[/tex]

∴ [tex]r(x)=ax+b[/tex] ⇒ [tex]r(x)=2x+5[/tex]

Hence, [tex]x^3-3x^2-12x+19[/tex] is divisible by [tex]x^2+x-6[/tex] when [tex]2x+5[/tex] is added to it.
