Lubov Fominskaja [6]

Answer:  A= s^2 <- for a square

A= 1/2*b*h <- for a triangle

A= 4^2= 16

A= 1/2*8*6 (The whole height is 8 yd)

A= 1/2*48

A= 24

24+16= 40 yd^2

"B" is the answer.

I hope this helps!

Given the definitions of f(x) and g(x) below, find the value of g(f(-1)).
Reptile [31]

Answer:

-14

Step-by-step explanation:

f(x) = -4x – 7 \\ plug \: x =  - 1 \\ f( - 1) =  - 4( - 1) - 7 = 4 - 7 =  - 3 \\g(x) = x² + 7x – 2 \\g(f( - 1)) =  {( - 3)}^{2}  + 7( - 3) - 2 \\  = 9 - 21 - 2 \\= - 14

Square ABCD is shown with four congruent images such that ABCD FGHI JKLM NOPQ RSTU.
Anettt [7]

Answer:

  • <em><u>RSTU</u></em>

Explanation:

The question states the <em>congruent</em> images:

  • ABCD ≅ FGHI ≅ JKLM ≅ NOPQ ≅ RSTU

The order of the letters matters.

For instance, ABCD ≅ FGHI means that the vertex A is transformed into vertex F, the vertex B is transformed into the vertex G, the vertex C is transformed into vertex H, and the vertex D is transformed into vertex I.

From the images, the square ABCD is just shifted 9 units down to form the square FGHI. No refelection is needed.

As per the square RSTU only a reflection of square ABCE accross the y-axis makes the vertex A into vertex R, the vertex B into the vertex S, the vertex C into the vertex T, and the vertex D into the vertex U.
