Answer:

Step-by-step explanation:

A quarter circle is one fourth of a circle. To find the area of a quarter circle, find the area of the whole circle by using the formula A = pi * r^2 and then divide by 4. To find the perimeter of the quarter circle, find the circumference of the whole circle, divide by 4, and then add the radius twice.

Which two points are on the graph of M(a) = - 3/4a-12?

sertanlavr [38]

Answer:

(-16, 0) and (0,-12) are exactly two points on the graph of the given equation.

Step-by-step explanation:

Here, the given expression is : $M(a) = -\frac{3}{4} a-12$

Here, let M(a) = b

⇒The equation becomes $b = -\frac{3}{4} a-12$

Now, check for all the given points for (a,b)

<u>1) FOR (-9,0)</u>

$RHS is -\frac{3}{4} (-9)-12 = -5.25 \neq 0$

Hence, (-9,0) is NOT on the graph.

<u>2) FOR (-16,0)</u>

Here, LHS = b = 0

and $RHS = -\frac{3}{4} (-16)-12 = 12-12 = 0$

Hence, LHS = RHS = 0 So, (-16,0) is on the graph.

<u>3) FOR (0,12)</u>

Here, LHS = b = 12

$RHS is -\frac{3}{4} (0)-12 = -12 \neq 12$

Hence, (0,12) is NOT on the graph.

<u>4) FOR (0,-12)</u>

Here, LHS = b = -12

$RHS is -\frac{3}{4} (0)-12 = -12$

and LHS = RHS = -12

Hence, (0,-12) is on the graph.

Hence, (-16, 0) and (0,-12) are exactly two points on the graph of the given equation.

What is the factored form of the expression?<br><br> 16b^2 – 81

solong [7]

Answer:

(4b-9) (4b+9)

Step-by-step explanation:

16b^2 – 81

This is the difference of squares

(a^2 -c^2) = (a-c) (a+c)

a^2 = 16b^2 so a= 4b

c^2 = 81 so c = 9

(16b^2 – 81) = (4b-9) (4b+9)

In VWX, the measure of

Naddika [18.5K]

Step-by-step explanation:

m<V+m<W+m<X=180° (sum of the interior angles)

m<V+20°+90°=180°

m<V=180-110°=70°

$\cos(70) = \frac{58}{vw}$

$vw = \frac{58}{ \cos(70) }$

$vw = \frac{58}{0.34} = 170.58 = 170.6$
