Hi there!

Given an equation in point-slope form, explain how to determine the coordinates of its y-intercept.

The y-intercept of a line occurs when x=0. Replace x with 0 in the equation and solve for y to find the y-intercept.

Given an equation or graph of a line, describe how to write an equation of a parallel line that goes through a given point.

Determine the slope of the line. In slope-intercept form [tex]y=mx+b[/tex], the slope would be [tex]m[/tex], and in point-slope form [tex]y-y_1=m(x-x_1)[/tex], the slope would be [tex]m[/tex] as well. Given a graph, it would be necessary to solve for the slope. Find two points and plug them into the equation [tex]m=\frac{\displaystyle y_2-y_1}{\displaystyle x_2-x_1}}[/tex] as [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] to solve for the slope.Parallel lines always have the same slope. Now that we've just solved for the slope, plug it into [tex]y=mx+b[/tex].Now, all that's left to solve in the equation is [tex]b[/tex]. Plug the given point into [tex]y=mx+b[/tex] along with the slope and solve for [tex]b[/tex].Plug both the slope and y-intercept back into [tex]y=mx+b[/tex] to achieve the final equation.

Given an equation or graph of a line, describe how to write an equation of a perpendicular line that goes through a given point.

Determine the slope of the line.Perpendicular lines always have slopes that are negative reciprocals. To determine the slope of a perpendicular line, take the slope from step 1 and find its negative reciprocal. For example, the negative reciprocal of 2 is -1/2. Plug this slope into [tex]y=mx+b[/tex].Now, all that's left to solve in the equation is [tex]b[/tex]. Plug the given point into [tex]y=mx+b[/tex] along with the slope and solve for [tex]b[/tex].Plug both the slope and the y-intercept back into [tex]y=mx+b[/tex] to achieve the final equation.

I hope this helps!

Substituting the values

6a + 3b = 34290

3a + 1535b = 183040

solving the two by suitable elimination

6a + 3b = 34290

3(2a+b) = 3×11430

2a + b = 11430....(i)

and 3a + 1535b=183040....(ii)

a=173620/3067 = 5660.91

Putting a=5660.91 in (i)

2(5660.91) + b = 11430

b = 108.81

∴ a = 5660.91 and b = 108.81

Now substituting the values in the equation y=a+bx

y = 5660.91 + 108.81x

y = 5660.91 + 108.81(X-1985)

in order to apply the law of cosines to find the length of the side of a triangle, is it enough to know which of the following?


A. The area of a triangle

B. The lengths of two of the triangle's sides and the measure of the angle between them

C. At least two of the angles of the triangle and the length of one of its sides

Answers

9514 1404 393

Answer:

  B. The lengths of two of the triangle's sides and the measure of the angle between them

Step-by-step explanation:

The usual formulation of the law of cosines is something like this:

  c² = a² +b² -2ab·cos(C)

where 'c' is the side opposite angle C, and 'a' and 'b' are the other two sides. That is, to use this formula directly, one needs two side lengths and the measure of the included angle.

_____

Additional comment

One can use the law of cosines to solve a triangle when any two sides and one angle are known. The use of the formula will give a quadratic in the unknown side length, if it is not the side opposite the known angle. As with the law of sines, if the angle is opposite the shorter of the two given sides, there may be two solutions for the length of the third side.

Answer:

  A : B : C = 6 : 10 : 7

Step-by-step explanation:

The A value is common to both ratios. In order to form the ratio A:B:C we must have the number of ratio units representing A be the same in both A:B and A:C. That number must be the least common multiple of 3 and 6, which is 6.

Multiplying the first ratio by 2, we have ...

  A : B = 6 : 10

  A : C = 6 : 7

So, we can write the triple ratio as ...

Answer:

[tex]y=-2x+6[/tex]

Step-by-step explanation:

Slope-intercept form is given as [tex]y=mx+b[/tex], where [tex]m[/tex] is slope and [tex]b[/tex] is the y-intercept.

To find the slope of a line that passes through two points [tex](x_1, x_2)[/tex] and [tex](y_1, y_2)[/tex], use the slope formula:

[tex]m=\frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}[/tex]

Let:

[tex](x_1, y_1)\implies (1, 4)\\(x_2, y_2)\implies (0, 6)[/tex]

The slope of the line that passes through these two points is:

[tex]m=\frac{6-4}{0-1}=\frac{2}{-1}=-2[/tex]

Now substitute [tex]m=-2[/tex] and any point to solve for [tex]b[/tex]:

[tex]y=mx+b,\\6=-2(0)+b,\\6=0+b,\\b=6[/tex]

Therefore, the slope-intercept form of a line that is represented by the table is [tex]\boxed{y=-2x+6}[/tex]

A man invested N80 at a certain rate of simple interest. If at the end of 5 years the money amounted to N88, what was the rate of simple interest paid?

Answers

9514 1404 393

Answer:

  2%

Step-by-step explanation:

The amount of interest is the difference between the total amount and the principal amount:

  N88 -N80 = N8 . . . . the amount of interest

The interest amount is given by the formula ...

  I = Prt

Solving for r, we find ...

  r = I/(Pt) = 8/(80×5) = 1/50 = 2%

The rate of simple interest paid was 2%.

Answer:

h= 60

g= 120

m= 147

k= 33

Step-by-step explanation:

We know that all three lines are straight an continuous, so, at any given point the angles should add up to 180 degrees.

This immediately helps with angle h:

    120 + h = 180

              h = 60

As well as m:

     33 + m = 180

              m = 147

There are two ways to solve the next part:

First and most familiar way:

    h + g = 180

    60 + g = 180

             g = 120

and:

    m + k = 180

    147 + k = 180

              k = 33

The other way that I prefer is that the angles opposite of each other when two lines intersect are equal. I don't know if that makes sense, it's hard to explain in this format.

Therefore, the null hypothesis which usually aligns with the population mean value will be stated as :

H0 : μ = 2 um

The alternative hypothesis is used to test the claim that the mean surface roughness is different from 2 ; hence no direction is given, this is thus a 2 - tailed test

While hovering near the top of Ribbon Falls in Yosemite National park at 1600 feet, a helicopter pilot accidentally drops his sunglasses. The height h(t) of the sunglasses after t second is given by the polynomial function h(t)=-16t^2+1600. When will the sunglasses hit the ground? (Hint: Let the height,h(t), be 0 and solve for t.)

Answers

Answer:

10 seconds

Step-by-step explanation:

Plug in 0 as h(t) and solve for t:

h(t) = -16t² + 1600

0 = -16t² + 1600

-1600 = -16t²

100 = t²

10 = t

So, the sunglasses will hit the ground after 10 seconds

Step-by-step explanation:

7.)

Supplementary angles add up to 180°. ∠B's supplement is 22°. This means ∠B is 158°. Since ∠A ≅ ∠B, the m∠A = 158°.

8.)

Again, supplementary angles add up to 180°. ∠P is a right angle meaning it is 90°. Therefore, the m∠Q is 90° as well.

9.)

Complementary angles add up to 90°. In order for ∠S and ∠T to be complementary, they both need to angle measurements less than 90° meaning they both need to be acute angles.

Now that we know that ∠T is acute, the only way ∠U can be its supplement is if it has an angle measure greater than 90°. Therefore, ∠U is an obtuse angle.

10.)

Similar to question 9, if an angle is obtuse, its supplement must be an acute angle.

Answer:

Step-by-step explanation:

Using the expression for the general term, you can fill in the known values and solve for the parameters of the sequence.

  an = a1 +d(n -1)

  a8 = a1 + d(8 -1) = 60

  a12 = a1 + d(12 -1) = 48

The difference of these equations is ...

  (a1 +7d) -(a1 +11d) = (60) -(48)

  -4d = 12

  d = -3

Substituting into the first equation, we have ...

  a1 +7(-3) = 60

  a1 = 81 . . . . . . . . . add 21

Then the 40th term is ...

  a40 = 81 -3(40 -1) = 81 -117

  a40 = -36

Part C of Jim and his dad are building a rectangular flower bed.
If Jim and his dad decide to decrease the width of the flower bed from 15 feet, what happens to its length?

Answers

i gotchu

The perimeter is 35. If we were to change the width, which is one of the dimensions of the flower bed, The perimeter will change. This means that perimeter will no longer be 35. So in order to keep the perimeter as it is, if we change one dimension, we must also change the other.

Let's solve for the length, using the formula to see how much the length changes from.

p = 2l + 2w

35 = 2l + 2(15)

35 = 2l + 30

5 = 2l

2.5 = l


We must increase the length from 2.5 feet. This is because decreasing one dimension will decrease the perimeter. But if we increase the other dimension as well, it will restore the perimeter to where is was initially.

B) 3, 11, 19, 27
C) 8, 5, 2, –1
D) 3, –5, –13, –21

Answers

Answer:

A

Step-by-step explanation:

an arithmetic sequence adds a constant from every previous term to create the next term.

it starts with a first term, a1, meaning that n >=1

a1 = 8 + 3×(1-1) = 8 + 3×0 = 8

so, B and D are out.

the next term is a2.

a2 = 8 + 3×(2-1) = 8 + 3×1 = 11

and so, only A can be correct.

just to verify

a3 = 8 + 3×(3-1) = 14

a4 = 8 + 3×(4-1) = 17

and it also fits overall,

starting with 8, every new term is the previous term + 3.
