Answer:

A. -21

Step-by-step explanation:

-3[5 - (-8 + 6)] =

Start with the innermost parentheses.

= -3[5 - (-2)]

Change the subtraction in the parentheses to an addition and do it.

= -3[5 + 2]

= -3[7]

= - 21

A small manufacturer constructs refrigerators. the fixed monthly cost is $200,000, and it costs $450 to produce one refrigerator

Horizontal asymptote of c(x) is 450.

<h3>What is Horizontal asymptote?</h3>

A horizontal asymptote is a line that guides the graph of a function for x-values but is not itself a part of the graph. "far," either "far" to the right or "far" to the left. Eventually, whether the graph is large enough or little, it may intersect.

<h3>According to the information:</h3>

Since we have given that

Cost to produce one refrigerator = $450

Fixed monthly cost = $200,000

Thus, the following formula represents the average cost to produce x refrigerators:

C(x) = (200000 + 450x)/x

Horizontal asymptote of c(x) would be

= 450x/x

= 450

Hence, Horizontal asymptote of c(x) is 450

Oscar cuts grass for $20 a lawn. He is saving to purchase an Mp3 player that costs $249.99. He will also have to pay 6% saless t

Anna35 [415]

He would have to mow 14 lawns. To find the answer you would multiply 249.99 by 6%, then add the answer and round and you would get 264.99. 20 x 14 equals $280, so if he mowed 14 lawns and get $20 per lawn, he would buy the Mp3 and still have 15.01 leftover.

Hope this helps!

I need help with these two trigonometry problems.

Sloan [31]

Answer:

$B \approx 32.1\°; A \approx 39.0\°$

Step-by-step explanation:

Sine theorem: in any triangle, the ratio between a side and the sine of the opposite angle is constant

$\frac{sin\ \alpha}a = \frac{sin\ \beta}b =\frac{sin\ \gamma}c$

In our case, for the left triangle,

$\frac {sin\ 103\°}{11} =\frac{sin\ B} 6 \rightarrow sin\ B = \frac6{11} sin\ 103\°$

Time to grab a calculator and crunch numbers. Double check your calculator is in degrees and not in radians (plug in sin 30°, if you're getting 0.5 you're good) and you will get

$sin\ B \approx 0.53 \rightarrow B \approx 32.1\°$

Same difference with the right triangle. With the same calculations

$sin\ A = \frac{26}{41} sin 83\° \approx 0.68 \rightarrow A \approx 39.0\°$

Let f(x)=4x^2-2<br> f(t+1)

dusya [7]

Answer:

$f(x) = 4 {x}^{2} - 2 \\ f(t + 1) = 4 {(t + 1)}^{2} - 2 \\ = 4( t + 1)(t + 1) - 2 \\ = 4( {t}^{2} + 2t + 1) - 2 \\ = 4 {t}^{2} + 8t + 4 - 2 \\ = 4 {t}^{2} + 8t + 2$
