Finds the height of a triangle with a base of 35 ft and an area of 262.5 ft2

Mathematics

The answer to this is that the height is equal to 15 feet. This is because to find the area of a triangle the equation is A=1/2bh. So what you have to do is do the opposite. Input the numbers into the equation 262.5= 1/2(35)h. Then multply 1/2 by 35 to get 17.5h. Next you divide each side by 17.5 and you get 15.

Answer:

(-2, 11) and (2, 3)

Step-by-step explanation:

<u>Given system of equations:</u>

1) f(x) = x² - 2x + 3 ⇒ y = x² - 2x + 3

2) f(x) = -2x + 7 ⇒ y = -2x + 7

Solve Using the Substitution Method:

<u>Step 1:</u> Substitute the the first equation into the second.

⇒ x² - 2x + 3 = -2x + 7

<u>Step 2:</u> Solve for x.

x² - 2x + 3 = -2x + 7 [ Add 2x to both sides. ]

x² - 2x + 2x + 3 = -2x + 2x + 7

⇒ x² + 3 = 7 [ Subtract 3 from both sides. ]

x² + 3 - 3 = 7 - 3

⇒ x² = 4 [ Take the square root of both sides. ]

√x² = √4

x = ± 2

⇒ x = -2, x = 2

<u>Step 3:</u> Solve for y.

<em>Substitute the found x-values into one of the given equations.</em>

y = -2x + 7 ⇒ y = -2(-2) + 7 ⇒ y = 4 + 7 ⇒ y = 11

y = -2x + 7 ⇒ y = -2(2) + 7 ⇒ y = -4 + 7 ⇒ y = 3

The solutions to the system of equations are: (-2, 11) and (2, 3).

Identify the domain and range of this graph​
RSB [31]

Answer:

domain is [-3,3] & range is [-3,3]

Step-by-step explanation:

When given a graph of a circle and ask to solve range and domain....

First: <u>find the four points</u> of the circle:

(-3,0);(3,0);(0,-3);(0,3) .   <em> **Best to plot these points on this graph to understand where the points are and what we are looking at.</em>

Second: Look for <u>range(vertical directions/left and right) and domain(horizontal direction/up and down)</u>.

domain: x-values, first coordinate  (-3,0) & (3,0)

range: y-values, second coordinate (0,-3);(0,3)

Third: take what you know and solve domain and range*include bracket to show domain and range

domain is [-3,3] & range is [-3,3]
