Answer:

a. FG ≈ 6.983 cm

b. FH = 13.16 cm

Step-by-step explanation:

Corresponding sides of similar triangles are proportional. This means ...

FG/GH = CD/DE

FG = GH(CD/DE) = (9.4 cm)(2.6/3.5) . . . . . . multiply by GH; fill in values

FG ≈ 6.983 cm

And ...

FH/GH = CE/DE

FH = GH(CE/DE) = (9.4 cm)(4.9/3.5)

FH = 13.16 cm

<em>Additional comment</em>

Corresponding vertices are listed in the same order in the similarity statements. This means, for example, segment FG (which names the first two vertices in the name of ΔFGH) will correspond to segment CD (which names the first two vertices of ΔCDE).

What is the inverse of the function f(x) = 1/4x – 12?

arlik [135]

To find the inverse all you do is swap your x and y then solve it through. for this one you gotta take f(x) and make it y

y = 1/4x - 12

then swap

x = 1/4y - 12

then solve it through

x - 12 = 1/4y

divide by (1/4)

and (x - 12)4 = y should be your answer

F(x) =x2-17x+60 how to find the zeros of the function

sergiy2304 [10]

Answer:

x = 1&16

Step-by-step explanation:

f(x) = 0 then

0 =x^2 - 17x + 16

(x-1)(x-16) =0

x -1 =0 or x-16=0

x =1 & x = 16

A swimming pool at a park measures 9.75 meters by 7.2 meters.

neonofarm [45]

Answer:

Part a) The area of the swimming pool is $70.2\ m^2$

Part b) The total area of the swimming pool and the playground is $105.3\ m^2$

Step-by-step explanation:

Part a) Find the area of the swimming pool

we know that

The area of the swimming pool is

$A=LW$

where

L is the length side

W is the width side

we have

$L=9.75\ m\\W=7.2\ m$

substitute the values

$A=(9.75)(7.2)$

$A=70.2\ m^2$

therefore

The area of the swimming pool is $70.2\ m^2$

Part b) The area of the playground is one and a half times that of the swimming pool. Find the total area of the swimming pool and the playground

we know that

To obtain the area of the playground multiply the area of the swimming pool by one and a half

$\frac{1}{2}(70.2)=35.1\ m^2$

To obtain the total area of the swimming pool and the playground, adds the area of the swimming pool and the area of the playground

$70.2\ m^2+35.1\ m^2=105.3\ m^2$

therefore

The total area of the swimming pool and the playground is $105.3\ m^2$

What is are if a rectangle of length of 5 and width of 3x-5y+6What is the area of a rectangle with a length of 5 and a width of

lawyer [7]

The area of rectangle is 15x - 25y + 30 sqaure units

<em><u>Solution:</u></em>

Given that, a rectangle with a length of 5 and a width of 3x - 5y + 6

To find: Area of rectangle

<em><u>The area of rectangle is given by formula:</u></em>

$Area = length \times width$

From given,

Length = 5

Width = 3x - 5y + 6

<em><u>Substituting the values in formula, we get,</u></em>

$Area = 5 \times (3x - 5y + 6)\\\\\text{Multiply 5 with each term inside the bracket }\\\\Area = 5(3x) -(5)(5y) +5(6)\\\\\text{Simplify the above expression }\\\\Area = 15x -25y + 30$

Thus area of rectangle is 15x - 25y + 30 sqaure units
