Step-by-step explanation:

[tex]9x^{2}y^{-2}[/tex]

If We replace x by -3 and y by 2 we get  :

[tex]9\left( -3\right)^{2} \left( 2\right)^{-2}[/tex]

Or we have :

[tex]\left( -3\right)^{2} =9\ \text{and} \ \left( 2\right)^{-2} =\frac{1}{2^{2}} =\frac{1}{4}[/tex]

then

[tex]9\left( -3\right)^{2} \left( 2\right)^{-2}=9\times9\times\frac{1}{4} = \frac{81}{4}[/tex]

on the other hand :

[tex]\frac{81}{4} =\frac{80+1}{4} =\frac{80}{4} +\frac{1}{4} =20+\frac{1}{4}=20\frac{1}{4}[/tex]

Answer:

b) 70.6

Step-by-step explanation:

To calculate average you need to add up all the numbers and divide by the quantity of numbers. They are calculating with mph, with ten hours, so there will be ten numbers. First you do 73 x 6 (6 because of 6 hours of 73 mph) which is 438. Then you do 67 x 4 which is 268. you add it up, then find a total of 706. Then you divide it by ten to find the answer 70.6

Answer:

Lower Left!!

Step-by-step explanation:

Because Gina doesn't have the total price, that makes it the unknown or "?" answer, with the price before tax obviously $300.00, and the tax being 8%. Therefore, it's the lower left option.

Step-by-step explanation:

circumference= 3.14m

the radius of the circle

Circumference of a circle = 2πr

Given, circumference = 3.14 meters

Therefore:

2πr = Circumference of a circle

2πr = 3.14

2 × 3.14r = 3.14,[Putting the value of pi (π) = 3.14]

6.28r = 3.14

r = 3.14/6.28

r = 0.5

Answer:

If one counts the blocks on the graph from the school to the stadium and back, there are three blocks one way and three blocks going back.

Altogether 6 blocks.

If Catelyn lives halfway between the park and the school, the amount of blocks is 5.

She lives halfway between.  Hence, what is 5 divided by 2?

2.5 or 2 1/2 blocks.

Step-by-step explanation:

The solutions of the given equation are x = 4 or x = -5.

The solution of a linear equation is defined as the points, in which the lines represent the intersection of two linear equations.

Given is an equation, 3(x – 4)(x + 5) = 0 we need to find the solution of the equation,

So, we can see that the equation is a quadratic equation, so it will have two solutions,

The equation is already in factored form,

So,

3(x – 4)(x + 5) = 0

Solution,

x-4 = 0

x = 4

x+5 = 0

x = -5

Hence, the solutions of the given equation are x = 4 or x = -5.

Remark

Make a very crude diagram of what these points look like. You will find that

That gives you a hint about how to find the Length and width.

Givens

From (-8,-3) and (-3, 3) L = -8 - -3 = - 5

From (-8,6) and  (-8,3) w = 6 - 3 = 3

Solution

The length cannot be minus 5. The way to get around that is to call it and absolute value of (-5) which is 5

So the area = L*W

area = 5 *3

area = 15

Here C is the Temperature in Celsius Degrees and F is temperature in Fahrenheit Degrees.

Time for substitution

I have put 40 instead of F because the value I have in hand is temperature in Farhenheit.

=> (40 -32) 5

Answer:

3. -1/3  ± 2i√5 / 3

Step-by-step explanation:

3x^2 + 2x = -7

Divide through by 3:

x^2 + 2/3 x = -7/3

Completing the square:

x^2 + 2/3 x + (1/3)^2 = -7/3 + (1/3)^2

(x + 1/3)^2 = -7/3 + 1/9

(x + 1/3)^2 = -20/9

x + 1/3 =  ±√(-20) / 3

x + 1/3 = ± 2√-5/3

x  = -1/3  ± 2i√5 / 3

Step-by-step explanation:

it means the shape of the balloon is close to a sphere.

the volume of a sphere is

4×pi×r³

so, it bases on r³.

that means any scaling factor f between 2 similar balloons for the radius has to be multiplied in 3 times (once for every "r").

in our case we know

8.4 = 2.8 × f

f = 8.4 / 2.8 = 3

so,

large volume = small volume × f×f×f =

= small volume × f³ = 92×3³ = 92×27 =

= 2,484 cm³

Answer:

The answer is 12

Step-by-step explanation:

Answer: 12

Step-by-step explanation:

Option B will be the best option.

The coordinates of the final vertices of the two transformations are W" = (-4,1), X" = (-2,1), Y" = (-2,4) and Z" = (-3,2)

The coordinates of the polygon WXYZ are:

W = (-4,-1)

X = (-2,-1)

Y = (-2,-4)

Z = (-3,-2)

When reflected across the y-axis, the rule of transformation is:

(x,y) -> (-x,y)

So, we have:

W' = (4,-1)

X' = (2,-1)

Y' = (2,-4)

Z' = (3,-2)

When rotated by 180 degrees, the rule of transformation is:

(x,y) -> (-x,-y)

So, we have:

W" = (-4,1)

X" = (-2,1)

Y" = (-2,4)

Z" = (-3,2)

Hence, the coordinates of the final vertices of the two transformations are W" = (-4,1), X" = (-2,1), Y" = (-2,4) and Z" = (-3,2)

Therefore,

Since  the resulting function has a leading degree of 1, hence the set or ordered pairs (1,6), (2,9), (3,12), (4,15) satisfies a linear function

The standard equation of a linear function is y = mx + b

where:

m is the slopee

b is the y-intercept

Using the coordinate point (1, 6) and (2, 9)

Find the slope

Slope = 9-6/2-1
Slope = 3/1

Slope = 3

For the y-intercept

Recall that y = mx + b

9 = 3(2) + b

b = 3

Determine the equation

y = 3x + 3

Since the resulting function has a leading degree of 1, hence the set or ordered pairs (1,6), (2,9), (3,12), (4,15) satisfies a linear function.
