Evaluate 3P4, I didn’t understand this question but if you know it would great if you could explain!!!

How do you do solving two-step equasions

Natali5045456 [20]

Answer:

The goal of solving two-step equations is to isolate the variable (get it by itself) and solve for the value using the following steps:

1. Add or subtract the constant term from both sides of the equation.

2. Multiply or divide the coefficient from both sides of the equation.

Step-by-step explanation:

Solving equations means using inverse (opposite) operations.

subtraction - addition

multiplication - division

In order to get the variable by itself, you need to first get rid of the constant (the number by itself) by adding or subtracting from both sides of the equal sign. Then, you multiply or divide by the coefficient of the variable to solve for the variable.

If tan θ=−52 and θis a quadrant II angle, what is cosθ?

marysya [2.9K]

The value of cos theta is -2/√29

<h3>Trigonometry identity</h3>

A trigonometry identity are expressions expressed as cosine, tangent, sine.

Given the expression below

tan θ =−5/2 = opp/adj

Determine the hypotenuse

hyp² =5^2 + 2^2

hyp² = 25 + 4

hyp = √29

Determine the value of cos theta

cos theta= adj/hyp

cos theta= -2/√29

Hence the value of cos theta is -2/√29

Set up and evaluate an integral for the volume of a right pyramid whose height is 2 and whose base is a square with a side of 1?

rjkz [21]

Answer:

$\mathbf{ \int^2_0 \dfrac{x^2}{4}. dx = \dfrac{2}{3}}$

Step-by-step explanation:

The volume of right pyramid whose base is a square is expressed by the formula:

$V = \int^h_o \dfrac{L^2 *y^2}{h^2}. dy \ or \ V = \int^h_o \dfrac{L^2 *x^2}{h^2}. dx$

Given that:

height h = 2; &

side (l) = 1

Then;

$V = \int^2_0 \dfrac{(1)^2 *x^2}{(2)^2}. dx$

$V = \int^2_0 \dfrac{x^2}{4}. dx$

$V =\dfrac{1}{4} \Big [ \dfrac{x^3}{3} \Big ] ^2_0$

$V =\dfrac{1}{4} \Big [ \dfrac{(2)^3}{3} -0\Big ]$

$V =\dfrac{1}{4} \Big [ \dfrac{8}{3} -0\Big ]$

$\mathbf{V = \dfrac{2}{3}}$

The equation y = 0.002x - 0.30 can be used to determine the approximate cost, y in dollars, of producing x items. How many items

ArbitrLikvidat [17]

Answer:

193650

Step-by-step explanation:

Since the cost must be no more than 387$, you can substitute that number instead of y to get 387 = 0.002x - 0.30. you can add 0.30 to both sides to get 387.3 = 0.002x

Then you can divide both sides by 0.002 to get 387.3/0.002 = 193650
