Help please !!:) For y =3x -2x^2 +5x^3 show how to find the value for y when x = 3

victus00 [196]

y = 3x-2x∧2+5x∧3

When we replace x with value 3 we get

y = 3 * 3 - 2 * 3∧2 + 5 * 3∧3 => y = 9-2*9+5*27 => y = 9-18+135 => y = 126

good luck!!!

X= A. 115.5 B. 137 C. 180

zhuklara [117]

Answer:

The correct answer option is C. 180

Step-by-step explanation:

We are given a figure of a circle with two known angles measuring 137 degrees and 94 degrees and we are to find the value of x.

Finding x:

$137 = \frac{1}{2} (\angle x + 94)$

$137 = \frac{1}{2} \angle x + 47$

$\frac{1}{2} \angle x = 137 - 47$

$\frac{1}{2} \angle x = 90
$

$\angle x = 90 \times 2&# 1 0$

x = 180

Helppppp! Which answer choice correctly describes the relationship between two of the lines in the figure?

Delicious77 [7]

I would have to say that it is the 3rd answer choice due to the right angle that is formed between line C and line A.

Solve each calculation. Be sure to report your answer with the correct number of significant figures.

Serjik [45]

Question:

Solve each calculation. Be sure to report your answer with the correct number of significant figures.

5.61000 dg × 1.1010 dg

12.0 m ÷ 3.1415 m

Answer:

1. $5.61000dg * 1.1010dg$ = $6.177 dg^2$

2. $\frac{12}{3.1415} = 3.8198$

Step-by-step explanation:

1. 5.61000 dg × 1.1010 dg

We start by representing each digit using scientific notation

$5.61000 = 561000 * 10^{-5}$

$1.1010 = 11010 * 10^{-4}$

Then, Multiply both numbers

$561000 * 10^{-5} * 11010 * 10^{-4}$

First, rearrange

$561000 * 11010 * 10^{-5} * 10^{-4}$

$6176610000 * 10^{-5} * 10^{-4}$

From law of indices, $10^{-5} * 10^{-4} = 10^{-9}$ ;

So, we have

$6176610000 * 10^{-9}$

$6.176610000$

Because 5.61000 is given in 3 significant figures and 1.1010 is given in 4 significant figures, we approximate the result to 4 significant figures

This gives $6.177$
