Answer 1

Answer:

a) root77

b) 2 root77 / ~17.55 cm^2

Step-by-step explanation:

a) by using Pythagorean Theroem,

a^2 + b^2 = c^2

2^2 + b^2 = 9^2

4 + b^2 = 81

81 - 4 = b^2

77 = b^2

root77 = b

b) 1/2bh is the quation for area thus,

area = 1/2 ( 4 ) ( root77)

area = 2 root77

or area = ~17.55 cm^2

Answer 2
Answer:

h = [tex]\sqrt{77}[/tex]

A =[tex]2\sqrt{77}[/tex]

Step-by-step explanation:

Rules for solving this problem:

Isosceles triangle rules

∠C = ∠ABC = BA

Because of isosceles being made up of two right triangles; using the pythagorean theorem we can deduce that

(1/2 x AC)² = BC² - h² (1/2 x AC)² = BA² - h²

Area of a triangle

A = 1/2 (Base x Height) = 1/2 * bh

Step 1 - Find the height

[tex]h =\sqrt{9^2 - ((1/2)AC)^2} = \sqrt{9^2 - ((1/2)~4)^2} = \sqrt{9^2 - 2^2} = \sqrt{81-4} = \sqrt {77}[/tex]

Step 2 - Find the area

[tex]A = \frac{1}{2}bh = (\frac{1}{2})(4)(\sqrt{77}) = 2 \sqrt{77}[/tex]

-15.6= -3.1+w/5 i didnt even learn this ;-;

Answers

Answer:

w = - 62.5

Step-by-step explanation:

Given

- 15.6 = - 3.1 + [tex]\frac{w}{5}[/tex] ( add 3.1 to both sides )

- 12.5 = [tex]\frac{w}{5}[/tex] ( multiply both sides by 5 to clear the fraction )

- 62.5 = w

Answer:

w= -62.5

Step-by-step explanation:

Simplifiying both sides of the equation, then isolating the variable.

180 minus what = 45

i really need this answer thank you

Answers

Answer: 135

Step-by-step explanation: All you need to do is 180-45=135.

The 180 minus 135 is equal to 45.

To find the value that, when subtracted from 180, gives a result of 45,  set up the following equation:

180 - x = 45

To solve for x,  to isolate it on one side of the equation by subtracting 180 from both sides:

180 - 180 - x = 45 - 180

Simplifying:

-x = -135

Now, to solve for x,  multiply both sides of the equation by -1 to change the sign:

(-1) × (-x) = (-1) × (-135)

x = 135

What is the equation for this line? *

O y = -2x +1
O y = 1/2x + 1
O y = -2x - 1
O y = -1/2x + 1

Answers

Answer:

y = -2x + 1

Step-by-step explanation:

The y-intercept is given by the point that is on the y-axis. (1)

This means that the answer contains a +1

Then you must find  if the slope is positive or negative

In this case the slope is negative because the line goes "downhill" from left to right

Since the slope is negative it means that there will be a negative sign in the beginning of the equation

Next, to find the slope you need to find the rise over run

Since it is a negative slope the rise will be negative and the run will be positive.

To find the slope find two clear points on the graph such as (0,1) and (2,0)

To find the slope, use the slope formula

This would look like: (0-2)/(1-0)

Your slope will be -2x

Piece it all together and you get a final answer of y= -2x+1

The answer is y= -1/2x + 1
