Answer:

163

Step-by-step explanation:

180 is the sum of all degrees.

subtract 22 from that to get 158

so X-5 = 158

you add a 5 to both sides: X+5-5=158+5

you cancel the fives in the first side of the equation and add 5 to 158 on the other side.

X=158+5

X=163

#5 The MAC is 4 centimeters. Find the circumference of B. Round your answer to the hundredths.

bixtya [17]

Answer:

C ≈ 11.71 cm

Step-by-step explanation:

using the ratio arc AC : circumference C = angle at centre of sector : 360°

$\frac{AC}{C}$ = $\frac{123}{360}$ , that is

$\frac{4}{C}$ = $\frac{123}{360}$ ( cross- multiply )

123 × C = 4 × 360 = 1440 ( divide both sides by 123 )

C = $\frac{1440}{123}$ ≈ 11.71 cm ( to the nearest hundredth )

The total cost of making a daily taco special for a restaurant is represented by the function C (t) = 2.5t + 1 , where t is the

dexar [7]

Answer:

C. The total cost increases by $2.50

Step-by-step explanation:

This is because 1 dollar is constent--- you will always have 1 dollar.

However 2.5 is the change, you have to times a number to get the answer.

EX:

(t) = 2.5t + 1

(4) = 2.5( 4) + 1 ----- plug in 4 for t

= 10 +1

= 11

The is the multiplyer or change is the 2.5t

and when you graph it it will almost always be the slope of the line.

Will mark brainiest for simplest and most coherent answer. What does it mean if an x (input) or y (output) value doesn't make se

Maksim231197 [3]

Answer:

I tried to answer but I still would like to know what doesn't make sense.

Considering the identity:

$\sec^2\theta-\tan^2\theta=1 \implies |\sec\theta|\geq1$

$\forall\;\theta\in\mathbb{R}-\{(2n+1)\frac{\pi}{2}, n\in\mathbb{Z} \}$

The identity is true whenever both sides are defined. It is not supposed to hold the values when we have division by zero, because it is undefined.

If the value doesn't make sense, it is probably not a function, or it is undefined by the given value of $x$ .

Let's go back to the definition of function again:

A function relates a set of inputs and a set of allowable outputs where each input is related to only one output. It basically defines the relation of ordered pairs.

Hope it helped you a bit.
