The answer should be C, unless Hunter is willing to earn 90 points exactly, then the answer would be B

What is the area of this triangle?<br><br> A=bh2

Galina-37 [17]

Alright, so you know that the formula for the area of a triangle is a=bh/2

First start out by identifying your base and height.

Base is the side that the shape is "standing on", in this case, that would be 9cm.

Now, the height is the measurement that is perpendicular (90 degrees to the base), which in this case is 12 cm.

Now, plug these values into your formula

(12)(9) /2 = 54 cm squared! hope this helps :)

A cricular arena is lit by 5 lights equally spaced around the perimeter of the arena. What is the measure of each angle formed b

Kitty [74]

Answer:

108°

Step-by-step explanation:

Suppose that circle with center A is a circular arena. Points B, C, D, E and F are 5 lights. These 5 points form regular pentagon (because these 5 lights are equally spaced around the perimeter of the arena).

The sum of all interior angles of pentagon can be calculated using following formula

$(n-2)\cdot 180^{\circ},\\ \\(5-2)\cdot 180^{\circ}=3\cdot 180^{\circ}=540^{\circ}$

All interior angles in regular pentagon are of equal measure, so

$\dfrac{540^{\circ}}{5}=108^{\circ}$

Thus, the measure of each angle formed by the lights on the perimeter is 108°.

#6: Tell whether the function below is 1 point<br> linear or exponential.<br> *<br> f(x) = -1/4x + 5

Pachacha [2.7K]

Answer:

Linear function

Step-by-step explanation:

Given

$f(x) = -\frac{1}{4}x + 5$

Required

Linear or Exponential

A linear equation has the form: $f(x) = mx + c$ ;

An exponential has the form: $f(x) = ab^x$

By comparing both functions to: $f(x) = -\frac{1}{4}x + 5$

The linear function is similar to $f(x) = -\frac{1}{4}x + 5$

<em>Hence, the given function is a linear function.</em>

Is this a function?<br> ignore the graph above the one with the dots lol

Evgen [1.6K]

Answer:

No.

Step-by-step explanation:

Use a vertical line test.

Vertical line test: If you can draw a vertical line and it <u>does not</u> cross two points in the line, then it is a function.

So, we draw a line.

Draw it through 9,0

It intercepts two points so No. This is not a function.

Hope this helps plz hit the crown :D
