You subtract the known angle measurements from 180 because a straight line means the whole undivided angle is 180 degrees and the answer to the subtraction is your missing angle measurement
I hope this helps!!!

Which function is the result of vertically shrinking ƒ(x) = (x + 1)2 by a factor of 1∕6?

Mnenie [13.5K]

Answer:

$y=\frac{1}{6}(x+1)^2$ is the result of vertically shrinking

Step-by-step explanation:

Vertical stretch or shrink

$y=c \cdot f(x)$

a stretch by a factor of c if c>1

a shrink by a factor of c if c<1

c is the factor

We are given that factor = 1/6 <1

So, Vertical shrink

So, $y = \frac{1}{6} \cdot f(x)$

We are given that $f(x) = (x + 1)^2$

So, $y=\frac{1}{6}(x+1)^2$

Option D is true

Hence $y=\frac{1}{6}(x+1)^2$ is the result of vertically shrinking

Answer:

Step-by-step explanation:

xº=yº=90º they are perpendicular to each other.

51º+zº=180 angle in a straight line

zº=180-51

zº=129º

Answer:

x = $\frac{11}{7}$

Step-by-step explanation:

note that 64 = $2^{6}$ and 32 = $2^{5}$ , thus

$(2^{6}) ^{2x-1}$ = $(2^{5}) ^{x+1}$ , that is

$2^{6(2x-1)}$ = $2^{5(x+1)}$

$2^{12x-6}$ = $2^{5x+5}$

Since the bases on both sides are equal, then equate the exponents

12x - 6 = 5x + 5 ( subtract 5x from both sides )

7x - 6 = 5 ( add 6 to both sides )

7x = 11 ( divide both sides by 7 )

x = $\frac{11}{7}$

Cheng likes a modern lawn sculpture made of four identical solid right pyramids with square bases. He decides to create an exact

lara [203]

Answer:

d. $8\text{ ft}^3$

Step-by-step explanation:

We have been given that Cheng measures each edge of each base to be 2 feet. The height of the whole sculpture is 6 feet.

First of all, we will find height of each pyramid by dividing height of whole sculpture by 4 as:

$\frac{6\text{ ft}}{4}=1.5\text{ ft}$

We know that volume of a pyramid is equal to 1/3 of base area times height that is $V=\frac{bh}{3}$ , where b represents area of base.

$V=\frac{(2\text{ ft})^2\times\text{ 1.5 ft}}{3}=4\times 0.5\text{ ft}^3=2\text{ ft}^3$

Since volume of one pyramid is equal to 2 cubic feet, so volume of 4 pyramids will be 4 times 2 cubic feet that is 8 cubic feet.

Therefore, Cheng must purchase 8 cubic feet of material.
