A=πr^2s/360 multiply both sides by 360

360A=sπr^2 divide both sides by πr^2

s=360A/(πr^2)

It's D
but the problem is wrong
at the end shoud have been
Solve the equation for S to find the angle measure given the radius and the area of the SECTOR not the circle
if they give you the radius of the circle then...
the area is redundant since circle area is pi*r^2

A country's population in 1995 was 164 million. in 2001 it was 169 million. estimate the population in 2015 using the exponentia

Vaselesa [24]

1995. 164 million
2001. 169 million
t = 2001 - 1995 = 6
169 = $164 * p^{6}$
$p^{6} = \frac{169}{164}= 1.0304878 \\ p = \sqrt[6]{1.0304878}$
p = 1.00502
t 1 = 2015 - 2001 = 14
f ( t1 ) = $169 * 1.00502^{14}$
f (t1) = 169 * 1.0762 = 181.27
Answer: a country´s population in 2015 will be 181 million.

Dave receives a salary of $200 a week plus a commission of 10% of his weekly sales. An equation y = m x + b represents Dave’s we

vovangra [49]

Answer:

y = 0.1x+200

Step-by-step explanation:

First, let's establish that:

x is independent

y is dependent

Basically, the value of y will depend on what x is.

The problem states that the slope of the line is Dave's comission, so since he makes 10% of comission, we can make the slope as 0.1x (mx)

The problem also states that the y intercept (b) is Dave's base salary, and earlier in the problem it states that his base salary is $200 a week. Therefore, b=200

now, the equation is:

y=0.1x+200

Hope this helps!

If NTM is congruent to OUM, SP is congruent to SQ, S is the center of the circle, and OM = 18, find NT. Round the answer to the

Aleks [24]

OM=18, so OQ=QM=18/2=9.
Given QU=8
from figure OQU is a right angled triangle , so OU^2=OQ^2 + QU^2
OU^2 = 9*9 + 8*8 = 81+72=153;
OU=sqrt(153) = 12.37 =13(approx);
From given statements of congruent NT and OU will also be congruent or identical. So, NT=OU=13
