Answer:

The rule of dilation by a scale factor 4 is:

(x, y)  →  (4x, 4y)

P(4, 2)  →  (4x, 4y) = (4(4), 4(2)) = P'(16, 8)

Therefore, 4 will be the scale factor.

Step-by-step explanation:

Given the point

As the image coordinates of (4, 2) are (16, 8) after the scale factor, we need to determine what could be the scale factor.

It is clear that the coordinates of the image P'(16, 8) are 4 times the coordinates of the original point P(4, 2), which means the point P(4, 2) is dilated by a scale factor of 4.

Thus, the rule of dilation by a scale factor 4 is:

(x, y)  →  (4x, 4y)

P(4, 2)  →  (4x, 4y) = (4(4), 4(2)) = P'(16, 8)

Therefore, 4 will be the scale factor.

Answer:

given us,

slope= 0

(x1y1)= (3,-3)

here

(y-y1) =m(x-x1)

or, (y+3)=0(x-3)

or (y+3)= x-3

or, x+y= -3-3

x+y= -6

Answer:

Ingrid collected 3 times as many Food boxes as she did cans of Food.

Step-by-step explanation:

Ingrid collected 6 cans of food from the food bank.

Ingrid collected 18 boxes of food from the food bank.

In order to determine the relationship

let cans of food = x = 6

So the boxes of food will be 3x = 3*6 = 18

So the relation between Cans of food and boxes of food will be

Ingrid collected 3 times as many boxes as she did cans

Step-by-step explanation:

4. Not enough info, the shape is cut off. Are there 4 sides or 5? If there's a 5th side, is it slanted or parallel to the one labeled 10 ft?

5. The circle has a radius of 7 m, so its area is

π (7 m)² = 49π m²

Subtract from this the area of the white triangle. It has a base length equal to the diameter (i.e. twice the radius) of the circle, and a height equal to the radius, so its area is

1/2 (14 m) (7 m) = 49 m²

So the area of the shaded region is (49π - 49) m², or 49 (π - 1) m².

6. The rectangle has length 14 yd and height equal to the diameter of the circular cutout, 10 yd, so its area is

(14 yd) (10 yd) = 140 yd²

The circular cutout is a semicircle with radius 5 yd, so its area is

1/2 π (5 yd)² = 25π/2 yd²

Then the area of the shaded region is (140 - 25π/2) yd², or 1/2 (280 - 25π) yd².

7. The circle has radius 13 in, so its area is

π (13 in)² = 169π in²

The triangle has height 23 in and length 12 in, so its area is

1/2 (23 in) (12 in) = 138 in²

Then the area of the shaded region is (169π - 138) in².

8. The shaded region is a rectangle with a smaller rectangular cutout. The larger rectangle has height 19 cm and length 18 cm + 16 cm = 34 cm, so its area is

(19 cm) (34 cm) = 646 cm²

The smaller rectangular cutout has length 16 cm and height 19 cm - 16 cm = 3 cm, so its area is

(16 cm) (3 cm) = 48 cm²

Then the area of the shaded region is 646 cm² - 48 cm² = 598 cm².

9. The semicircular piece has radius 3 m, so its area is

1/2 π (3 m)² = 9π/2 m²

The triangle has height equal to the semicircle's diameter, 6 m, and length 9 m, so its area is

1/2 (6 m) (9 m) = 27 m²

Then the area of the shaded region is (9π/2 + 27) m², or 1/2 (9π + 54) m².

Answer:

-11.8, -30.8, and range is {7.2, 1.12, -4.2, -34.6}

Step-by-step explanation:

t(x)= -3.8x-4.2

Evaluate the function for

x=2 is t(x=2)=-3.8*2-4.2= -11.8

x=7 is t(x=7)=-3.8*7-4.2=-30.8

domain are the values of x and are {-3, -1.4, 0, 8}

the range are the values of y or values of t(x)

t(x=-3)= 11.4 -4.2 =7.2

t(x=-1.4)= 5.32 -4.2 =1.12

t(x=0)= -4.2

t(x=8)= -30.4-4.2= -34.6

so the range is {7.2, 1.12, -4.2, -34.6}

Answer:

3 is your answer.

Step-by-step explanation:

Divide 160 by 5 and you get 32. Multiply it by 3 to get to 96 so it ends up as 3.

Answer:

x = 3

Step-by-step explanation:

To find this, let's use a ratio of gallons of gas to miles the car is able to travel.

160 miles / 5 gallons is equal to 96 miles / x gallons, or 160/5 = 96/x.

Cross multiply to get 160x = (5)(96)

Multiply the 96 by the 5 to get 160x = 480

Divide both sides by 160 to get x = 3.

Answer:

2. 12.08

3. 7.74

Step-by-step explanation:

a squared + b squared = c squared

2. 5 squared = 25, 11 squared = 121, 25 + 121 = 146, the squre root of 146 is 12.08

3.19 squared = 361, 421 - 361 = 60 60 squared = 7.74

Answer:

For 2 the answer is 12. For 3 the answer is 28.

Step-by-step explanation:

These may be wrong but hopefully they are correct

My work:

[tex]5^2+11^2=146[/tex]   then [tex]\sqrt{146} = 12.08[/tex]

[tex]\sqrt{421}=20.5[/tex]    [tex]19^2+20.5^2=781.25[/tex]  then  [tex]\sqrt{781.25} =28[/tex]

Answer:

[tex]75 {x}^{ \frac{3}{2} } {y}^{6} {z}^{ \frac{11}{2} } [/tex]

Step-by-step explanation:

First thing is to multiply. We don't need to bother with the root for now.

[tex] \sqrt{15 {x}^{2} {y}^{11} {z}^{4} } \times \sqrt{5xy {z}^{7} } = \\ \sqrt{75 {x}^{3} {y}^{12} {z}^{11} } [/tex]

All I did was multiply the numbers and added the exponents for the variables.

Now all we have to do is divide the exponents in half for the variables, nothing is needed additionally for the 75.

[tex]75 {x}^{ \frac{3}{2} } {y}^{6} {z}^{ \frac{11}{2} }[/tex]

There you go, just a few steps and you have your answer.

You can simplify further by moving the answer for the root infront of the square root so it isn't as sloppy. This would make the simplest for to be

5xyz^5 (3xy)^(1/2)

Answer:

-2

Step-by-step explanation:

12 is the larger number so if you take a bigger number and subtract it from a smaller number you get negative

The value of the difference 10 - 12 is -2.

The difference between 10 and 12 is calculated by subtracting the smaller number from the larger number.

We have to find difference of 10 - 12.

When we subtract 12 from 10, we get a result of -2.

The negative sign indicates that 12 is greater than 10, and the absolute value of 2 represents the numerical difference between the two numbers.

So, the difference between 10 and 12 is -2.

Answer:

0.65 grams

Step-by-step explanation:

0.42 + 0.23 = 0.65

The total weight of both salt and pepper is 0.65 grams.

Decimals are one of the types of numbers, which has a whole number and the fractional part separated by a decimal point. The dot present between the whole number and fractions part is called the decimal point.

Given that, you have 0.42 grams of salt and add 0.23 grams of pepper.

Total weight = 0.42+0.23

= 0.65 grams

Therefore, the total weight of both salt and pepper is 0.65 grams.
