Answer: D

Step-by-step explanation:

To find the perimeter of the square, you want to first find the length of each side. Since the figure is a square, we know that each side is equal to each other. We can set the expressions equal to each other to find x.

\frac{3}{4}x-1=\frac{1}{2}x+7           [subtract both sides by 1/2x]

\frac{1}{4}x-1=7                    [add both sides by 1]

\frac{1}{4}x=8                           [multiply both sides by 4]

x=32

Now that we know x, we can plug it into each expression to find teh length of each side.

\frac{3}{4}(32)-1                       [multiply]

24-1                           [subtract]

23

Now that we know each side is equal to 23, we can add all the sides together to find the perimeter.

23+23+23+23=92        or          23×4=92

Since we know that the perimeter is 92 units, the answer is D.

Let f(x) = 2x - 1, g(x) = x²- 2 x+ 1. find (f• g ) (x)​
Nana76 [90]

Answer:

f•g(x) = f(x)•g(x)

f•g(x) = (2x-1) (x²-2x+1)

= 2x³-4x²+2x-x²+2x-1

= 2x³-5x²+4x-1

What is the tenth term of the geometric sequence that has a common ratio of `1/3` and 36 as its fifth term?
katrin [286]

\bf \begin{array}{llll} term&value\\ \cline{1-2} a_5&36\\ a_6&36\left( \frac{1}{3} \right)\\ a_7&36\left( \frac{1}{3} \right)\left( \frac{1}{3} \right)\\ a_8&36\left( \frac{1}{3} \right)\left( \frac{1}{3} \right)\left( \frac{1}{3} \right)\\ a_9&36\left( \frac{1}{3} \right)\left( \frac{1}{3} \right)\left( \frac{1}{3} \right)\left( \frac{1}{3} \right)\\ a_{10}&36\left( \frac{1}{3} \right)\left( \frac{1}{3} \right)\left( \frac{1}{3} \right)\left( \frac{1}{3} \right)\left( \frac{1}{3} \right) \end{array}

\bf a_{10}=36\left( \frac{1}{3} \right)^5\implies a_{10}=36\cdot \cfrac{1^5}{3^5}\implies a_{10}=\cfrac{36}{243}\implies a_{10}=\cfrac{4}{27}

For triangle Abc side a=18 angle C=90 and side b=24 find side c to the nearest whole number
ollegr [7]
...
Using the Pythagorean theorem, a² + b² = c², we can solve for 'c'.
We know the length of sides 'a' and 'b', and this is all we really need to know. The angle value of angle 'c' is irrelevant to finding the length of side 'c' (which I'm assuming is the hypotenuse).
18² + 24² = c².
324 +  576 = c².
900 = c². Now find the square root of 900 to get the value of 'c'.
30 = c. <= And there is your answer.

What is the vertex of the graph of y + 2x + 3 = –(x + 2)2 + 1? (–3, –33) (–3, 3) (3, –24) (3, 21)
Arte-miy333 [17]
ANSWER

(-3,3)

EXPLANATION

The given function is

y + 2x + 3 = - (x + 2) ^{2} + 1

Expand

y + 2x + 3 = - x ^{2} - 4x - 4 + 1

Rewrite in the form:

y =a {x}^{2} + bx + c

This implies that,

y = - x ^{2} - 4x - 2 x - 4 + 1 - 3

y = - {x}^{2} - 6x - 6

Complete the square to get,

y = - ( {x}^{2} + 6x) - 6

y = - ( {x}^{2} + 6x + {(3)}^{2} ) - - {(3)}^{2} - 6

y = - {(x + 3)}^{2} +9 - 6

y = - {(x + 3)}^{2} +3

The function is now in the form:

y = a {(x - h)}^{2} +k

where (h,k) =(-3,3) is the vertex
