Graph the image of the figure after a dilation with a scale factor of 1/2 centered at (-1, 3) use the plolygon tool to graph the triangle by connecting all its vertices.

i need this answer really fast and will give as many points as you want idc.

Answers

Answer:

See below.

Step-by-step explanation:

The coordinates of the original triangle are at

(-5, 3), (-5, 7), and (1, 7).

Since the scale factor is one-half, you are shrinking the triangle.

The coordinates of the dilated triangle will be half-way from those points to (-1, 3).

Thus, they will be at

(-3, 3), (-3,5), and (0,5).

In the image below, the green triangle is the original.

The red triangle is the dilated figure, and the black dashed lines are the dilation rays from (-1, 3).

List the names and corresponding speeds from least to greatest in miles per hour. Julie 62 miles per hour manalo 311,520 feet per hour and leshawn 1,448 meters per minute

Answers

Answer:

$\text{Ieshawn's speed}=\frac{53.98 km}{\text{Hour}}$ , $\text{Manalo's speed}=\frac{\text{59 miles}}{\text{hour}}$ , $\text{Julie's speed}=\frac{\text{62 miles}}{\text{hour}}$ .

Step-by-step explanation:

We have been given 3 different speeds. We are asked to list the names and corresponding speeds from least to greatest in miles per hour.

$\text{Julie's speed}=\frac{\text{62 miles}}{\text{hour}}$

$\text{Manalo's speed}=\frac{\text{311,520 feet}}{\text{hour}}$

$\text{Manalo's speed}=\frac{\text{311,520 feet}}{\text{hour}}* \frac{\text{1 mile}}{\text{5280 feet}}$

$\text{Manalo's speed}=\frac{\text{59 miles}}{\text{hour}}$

$\text{Ieshawn's speed}=\frac{\text{1,448 meters}}{\text{minute}}$

$\text{Ieshawn's speed}=\frac{\text{1,448 meters}}{\text{minute}}* \frac{\text{60 minutes}}{\text{Hour}}* \frac{\text{1 mile}}{\text{1609.34 meters}}$

$\text{Ieshawn's speed}=\frac{1,448 *60}{\text{Hour}}* \frac{\text{1 miles}}{1609.34}$

$\text{Ieshawn's speed}=\frac{86880 miles}{1609.34\text{Hour}}$

$\text{Ieshawn's speed}=\frac{53.98 miles}{\text{Hour}}$

Speeds from least to greatest in miles per hour:

$\text{Ieshawn's speed}=\frac{53.98 km}{\text{Hour}}$ , $\text{Manalo's speed}=\frac{\text{59 miles}}{\text{hour}}$ , $\text{Julie's speed}=\frac{\text{62 miles}}{\text{hour}}$ .

If the product of two positive fractions a and b is 15/56, find three pairs for possible values for a and b

Answers

Answer

Find out the three pairs for possible values for a and b .

To prove

As given

$The\ product\ of\ two\ positive\ fractions\ a\ and\ b\ is\ (15)/(56) .$

i.e it is written in the form.

$a* b = (15)/(56)$

When

$a = (3)/(2) , b = (5)/(28)$

Than

$(3* 5)/(2* 28) = (15)/(56)$

When

$a = (3)/(4) , b = (5)/(14)$

Than

$(3* 5)/(4* 14) = (15)/(56)$

When

$a = (1)/(2) , b = (15)/(28)$

Than

$(1* 15)/(2* 28) = (15)/(56)$

Hence proved

all you have to do is find pairs of factor for both 15 and 56
e.g. 1,15 3,5
1.56 2, 28 4, 14

so three possibilities could be
1/1 x 15/56
3/4 x 5/14
1/2 x 15/28

The Prime Factorization of 3,5,10 is:

3 = 1 x 3
5 = 1 x 5
10 = 2 x 5

Lets Multiply it:
We already have a 5, so we can only use one of the fives.

1 x 1 x 2 x 3 x 5 = 30

the answer is 30

find the smallest zero of f(x+5). x=?

Answers

Hope this helps :)

Answer:

k=13

x= -10

Step-by-step explanation:

f(x)=x²+3x-10

f(x+5)=

=(x+5)(x+5)+3(x+5)-10

=x²+10x+25+3x+15-10

=x²+13x+30

0=x²+13x+30

0=(x+3)(x+10)

x= -3 or -10

-10< -3

smallest zero is -10
