As shown in the graph, ΔGHI ≅ ΔG'H'I', since this is a vertical shift, and ΔG'H'I' ≅ ΔG''H''I'', since this is a horizontal shif

t.
We can also show that triangles GHI and G''H''I'' are congruent directly, by using the translation
A) (x, y) → (x + 3, y - 4).
B) (x, y) → (x - 3, y + 1).
C) (x, y) → (x + 2, y + 2).
D) (x, y) → (x + 4, y - 5).

Please help me find the slope of the graph thank you a, b, c, d (picture)
alisha [4.7K]

Answer:

D: -75 the balloon is descending at a rate of 75ft per minute

Step-by-step explanation:

To find the slope of any graph, take two points on the graph and subtract them y/x so to get this answer is used the points (0,450) and (2,300) and subtracted the y-values over the x-values

450-300=150

0-2=-2

150/-2 = -75

that is the slope and since it is negative and the slope itself is a diagonal line going towards the x-axis you know it’s descending.

Hope this helps :)

If (a-bi)^2 = 13 - 12i, what is the product of a and b?
VARVARA [1.3K]

Answer:

\large \boxed{\sf \ \ \ a\cdot b= 6 \ \ \ }

Step-by-step explanation:

Hello,

(a-bi)^2 = 13 - 12i\\\\ a^2+(bi)^2-2abi = 13-12i\\\\a^2-b^2-2abi=13-12i

Imaginary term must be the same so

-2ab=-12

2ab = 12

ab = 12/2 = 6

So the product of a and b is 6

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

1. when the expression x^3+ 2kx+2 is divided by x+2, the remainder is less than the remainder when the expression is divided by
nalin [4]

Answer:

let the polynomial be

f(x)=x³+2kx+2

is divided by

g(x)=x+2

hence

(x+2) is a factor of f(x)

so comparing with x-a we get a=-2

so

f(a)=0

f(-2)=(-2)³+2*-2*k+2

0=-8-4K+2

4k=-6

K=-6/4

k=-3/2

again

when divided by x+1

g(x)=x+1

hence

x+1 is a factor

so a=-1

f(-1)=-(1)³+2*-1*k+2

0=-1-2k+2

0=1-2k

k=1/2
