PLS HELP simplify (2b^3)^2

Mathematics
1 answer:
dexar [7]3 years ago
7 0

Answer: 4b^6

Remember if theres a bracket you multiply the power instead of adding

For example if it was 2b^3 x 2b^2 then the answer would be 4b^5 instead according to indices law, read up on it if you havent yet itll help a bunch! :)

How do I figure out the area and perimeter of these shapes and how do you figure out the unknown side? Q9
nydimaria [60]
To work out the area or perimeter of any compound shape, split the shape so that you are left with regular shapes e.g. for 9b split the shape and you will get two rectangles

Then you can easily work the area/perimeter of the shapes you made and add them up

Hope this helps :)

Solve for x I need help on this question
AlexFokin [52]

Answer:

x\approx7.8

Step-by-step explanation:

In relation to the given angle, we are given the triangle's opposite side and hypotenuse. Therefore, we use the sine function to set up a proportion and solve for the opposite side:

sin(\theta)=\frac{opposite}{hypotenuse}

sin(23^\circ)=\frac{x}{20}

20sin(23^\circ)=x

x=20sin(23^\circ)

x\approx7.8

Therefore, the length of the opposite side is about 7.8 units

Write an equation of the line shown. Then use the equation to find the value of x when y = 150​
Ymorist [56]

Answer:

y = 10x + 30

x = 12

Step-by-step explanation:

The slope-intercept form formula, y = mx + b, can be used to write an equation for the line.

Where,

m = slope = \frac{y_2 - y_1}{x_2 - x_1}

b = y-intercept, which is the point at which the line intercepts the y-axis. At this point, x = 0.

Let's find the slope (m) using the coordinates of the two points given, (0, 30), (3, 60).

m = \frac{y_2 - y_1}{x_2 - x_1}

Let,

(0, 30) = (x_1, y_1)

(3, 60) = (x_2, y_2)

m = \frac{60 - 30}{3 - 0}

m = \frac{30}{3}

m = 10

y-intercept of the line, b = 30

Equation for the line would be:

y = 10x + 30

Using the equation, find x when y = 150.

Simply substitute the value for y in the equation to find x.

150 = 10x + 30

Subtract 30 from both sides

150 - 30 = 10x + 30 - 30

120 = 10x

Divide both sides by 10

\frac{120}{10} = \frac{10x}{10}

12 = x

x = 12
