Without graphing, explain how you know the equation
y = - 1/2x^2 - 7 will be compressed
(compared to the parent function of y=x^2).

Answers

Answer:

 

" because the coefficient of the x^2 term is less than 1 (between -1 and + 1)  

y = x^2 looks like a big U with the vertex (bottom) "kissing" the origin (0,0)

if you add 1 to the equation y = x^2 + 1 it shifts UP one  

if you subtract 3 y = x^2 -3 it shifts down three ....

if you change it to look like this y = (x+4)^2 it shifts (slides) to the LEFT 4 units..

note that this slide is opposite to the sign + 4 left slide , - 4 right slide...

NOW YOUR QUESTION !!!! if the coefficient is > 1  

y = 99 x^2 then the graph gets "skinny" goes up faster...

if it is less than one (between -1 past 0 to +1 ) then it flattens out

Bottom line here your coefficient is a "-1/2"  

so YOUR GRAPH IS A ∩ (goes downward) and is FLATTER than the normal ∪

Rashaad leans a 16-foot ladder against a wall so that it forms an angle of 73° with the
ground. How high up the wall does the ladder reach? Round your answer to the
nearest hundredth of a foot if necessary.

Answers

Answer:

15.30 feet

Step-by-step explanation:

The ladder creates a right triangle with the wall and the ground. Because sine is the opposite divided the hypotenuse:

[tex]sin(73^{o}) = \frac{x}{16}[/tex] where x is the wall height that the ladder reaches.

Multiply both sides by 16 we get:

[tex]x = 16{sin(73^{o})}[/tex]

Using the calculator, we can get 15.30

The height up to which does the ladder reach will be equal to 15.30 feet

What is trigonometry?

The branch of mathematics dealing with the relations of the sides and angles of triangles and with the relevant functions of any angles.

The ladder creates a right triangle with the wall and the ground. Because sine is the opposite divided the hypotenuse:

[tex]\rm Sin 73=\dfrac{x}{16}[/tex]

where x is the wall height that the ladder reaches.

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

Explanation:

Unfortunately your teacher is a bit vague here, but I'm assuming that the roots listed in the table are the only roots (and there aren't any other roots possible). If other roots were possible, then we'd have infinitely many possible answers and it would greatly muddy up the problem.

So we'll just stick to the basic assumption that the only roots are: -2, 0, and 2.

With that key assumption in mind, let's look at the answer choices to see which are true and which are false.

A) False. This is because we see that f(x) = -15 when x = -3. Note how x = -3 is in the interval [tex](-\infty, 3)[/tex]. In other words, this is a counter example showing that f(x) > 0 is not the case when x is between -infinity and 3.B) True. Over the interval [tex]0 \le x \le 2[/tex], we have f(x) either equal to 0 or a negative value. For the interval 0 < x < 2, we would have f(x) < 0.C) False. The table shows that f(0) = 0 which means we aren't making f(x) < 0 to be the case. D) True. The table shows that if -2 < x < 0, then f(x) is positive. An example of this is f(-1) = 3 which is positive. The f(x) values in this region are above the x axis. E) True. We have f(x) either equal to 0 or something larger when [tex]x \ge 2[/tex] which translates over to the interval notation [tex][2, \infty)[/tex]

From that list above, we see that choices B, D and E are true.

Find the volume of a pyramid with a square base, where the area of the base is 12.5 ft ^2 12.5 ft
2
and the height of the pyramid is 16 ft. Round your answer to the nearest tenth of a cubic foot.

Answers

Answer:

833.3 ft^3

Step-by-step explanation:

The formula for the volume of a pyramid is:

V = (lwh)/3

V = volume

l = length of base

w = width of base

h = height of pyramid

Now we just correspond the values with the variables:

l = 12.5

w = 12.5

h = 16

And plug these values into the formula:

((12.5)(12.5)(16))/3

((156.25)(16))/3

2500/3

833.3 ft^3

Hope this helps (●'◡'●)

The solution is : the volume of a pyramid with a square base is 833.3 ft^3.

What is volume?

In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.

here, we have,

we know that,

The formula for the volume of a pyramid is:

V = (lwh)/3

V = volume

l = length of base

w = width of base

h = height of pyramid

Now we just correspond the values with the variables:

l = 12.5

w = 12.5

h = 16

And plug these values into the formula:

=((12.5)(12.5)(16))/3

=((156.25)(16))/3

=2500/3

=833.3 ft^3

Hence, The solution is : the volume of a pyramid with a square base is 833.3 ft^3.

A polynomial p has zeros when x = -2, x = 1/3, and x =3.
What could be the equation of p? Choose 1 answer:
a. p(x) = (x + 2)(x + 3)(3x + 1)
b. p(x) = (x + 2)(x + 3) (3x - 1)
C. p(x) = (x + 2)(x - 3)(3x - 1)
D. p(x) = (x - 2)(x + )(3x + 1)

Answers

Answer:

p(x) = ( x +2) (3x - 1) ( x-3)

Step-by-step explanation:

We know the equation for a polynomial with given zeros is

f(x) = a(x-b1) (x-b2)...... where b are the zeros and a is a constant

Since the zeros are x = -2, x = 1/3, and x =3.

p(x) = a( x - -2) (x - 1/3) ( x-3)

p(x) = a( x +2) (x - 1/3) ( x-3)

We can pick the value of a since we are not given a point on the function.  Pick a=3

p(x) = 3( x +2) (x - 1/3) ( x-3)

Rewriting the second term

p(x) = ( x +2) (3x - 1) ( x-3)

Help urgent In a class of 35 students 15 of them have cats 16 have dogs 3 hangs none how many probability does have both

Answers

Answer:

Step-by-step explanation:

Number of students who has cat and dogs = (15 + 16) - 22

                                                                       = 31 - 22 = 9

Number of students who has only cats = 15 - 9 = 6

What is defined term?

In geometry defined term, that have a formal definition and can be defined using other geometrical terms is called a defined term.

According to the given question

We have some terms

Angle, Line, Point and Plane

Now,

In geometry, we can define an angle using undefined term of a line. That is we define an angle as  the corners that are created when two non-parallel lines intersect each other, so angle is a defined term.

In Geometry, we define  a point as a location or size .

A line is defined as something that extends infinitely in either direction but has no width and is one dimensional.

While plane extends infinitely in two dimensions.

Hence, line, point and plane are undefined terms.

An isosceles triangle has been constructed so that its height is half its base. Find the dimensions of the
triangle if the area is 64 m².

Answers

Answer: 4 8×8= 64 half the base which is 8 =4

Step-by-step explanation:

Answer:

height = 8 m

base = 16 m

Step-by-step explanation:

Let base = 2x m

So, height = half its base = [tex]\frac{2x}{2} = x \ m[/tex]

Area = 64 m²

[tex]\frac{1}{2}* \ base* \ height = 64\\\\\\\frac{1}{2}* 2x * x = 64[/tex]

 x * x = 64

x * x = 8 * 8

x = 8 m

Base = 2x = 2*8 = 16 m

The population of a town is 157,220 and is decreasing at a rate of 0.8% each year. Predict the population in 5 years (round to the nearest whole number).

Answers

Answer:

151,031

Step-by-step explanation:

If the population of a town is decreasing at 0.8% each year, the new population of the town will be [tex]100\%-0.8\%=99.2\%[/tex] of what it was last year. To find 99.2% of something, multiply it by 0.992. Therefore, we can write the following equation:

[tex]f(x)=157,220\cdot 0.992^x[/tex], where [tex]f(x)[/tex] is the population of the town [tex]x[/tex] years after the town had a population of 157,220.

Substitute [tex]x=5[/tex] into this equation to get the projected population after 5 years:

[tex]f(5)=157,220\cdot 0.992^5, \\f(5)=151031.019048,\\f(5)\approx \boxed{151,031}[/tex]

Therefore, in 5 years, the population should be 151,031.
