The answer is -2/3 because you turn 3 1/3 into a improper fraction, 10/3, and then multiply that by -1/5 giving you the answer of -2/3.

Answer:

Answers are below

Step-by-step explanation:

Step 1: Graph the function

Step 2: Identify the type of function. This can be done by looking the exponents

Step 3: Since the exponent is 3, the function is not linear, but instead a cubic function.

I graphed this equation below.

Cloud [144]

Answer:

Step-by-step explanation:

Picture 1

In right triangle ABC,

Side AB is the opposite side of angle C.

Picture 2

In triangle MKL,

tan(∠M) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

= $\frac{KL}{KM}$

= $\frac{15}{8}$

Option (1) is the answer.

Picture 3

In ΔXYZ,

sin(∠Z) = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

= $\frac{XY}{XZ}$

For the length of XY we will apply Pythagoras theorem in ΔXYZ,

XZ² = XY² + YZ²

XY² = XZ² - YZ²

= (40)² - (32)²

XY = √576

= 24

sin(Z) = $\frac{24}{40}$

sin(Z) = $\frac{3}{5}$

Picture 4

In right triangle DEF,

Cos(D) = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

= $\frac{EF}{DF}$

= $\frac{75}{72}$

= $\frac{25}{24}$

Picture 5

In ΔABC,

tan(63°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

tan(63°) = $\frac{BC}{AB}$

AB = $\frac{BC}{\text{tan}(63)}$

AB = $\frac{8}{\text{tan}(63)}$

AB = 4.0762 ≈ 4 m

Option (3) will be the answer.

A factory produces 42,000 computer monitors per day. The manager of the factory claims that fewer than 660 defective computer mo

Oksana_A [137]

Answer:

<h2> The manager's claim is likely to be true.</h2>

Step-by-step explanation:

We are given that the factory produces 42,000 computer monitors per day

And the claim is of this amount produces fewer than 660 are defective.

a random sample shows that of 240 monitors 2 are defective

to verify the factory managers claim we need to know how many 240s are there in 42000

=42000/240= 175

Since each 240 will give 2 defective monitors

175 will give= 175*2= 350

350 is less than 660 hence the managers claim is correct

F(x) = x2 + 1 g(x) = 5 – x<br><br> (f + g)(x) =

Gnom [1K]

Answer:

$(f + g)(x) = {x}^{2} - x + 6$

Step-by-step explanation:

We have

$f(x) = {x}^{2} + 1$

and

$g(x) = 5 - x$

We want to find (f+g)(x).

By the algebraic properties of polynomial functions,

$(f + g)(x) = f(x) + g(x)$

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

This simplifies to

$(f + g)(x) = {x}^{2} - x + 6$

We can't simplify further, hence the simplest form
