Answer:

50 degrees

Step-by-step explanation:

We know that an inscribed angle in a circle is 1/2 the arc that it inscribes. So, therefore the arc is inscribed by the 25 degrees is 50. Assuming that the center of the circle is O, the center angle will be the arc measure. Knowing this, angle a is 50 degrees. If you're curious about all these theorems, they can be proved using similar triangles.

fyi, using the same logic, angle b is 25 degrees

Point Q is the midpoint between points P and R on a number line. If the coordinate of point Q is 6 and the coordinate of point P

nekit [7.7K]

Answer:

$R = 17$

Step-by-step explanation:

Given

$P = -5$

$Q = 6$

Midpoint: Q

Required

Determine R

Since Q is the midpoint, then

$Q = \frac{1}{2}(P + R)$

Substitute values for P and Q

$6 = \frac{1}{2}(-5 + R)$

Multiply both sides by 2

$12 = -5 + R$

Add 5 to both sides

$12 + 5 = -5 + 5 + R$

$17 = R$

$R = 17$

The population of a town was 5000 in 2010. The population grows at a rate of 1.4% annually.

kolbaska11 [484]

Answer:

a) P = 5000(1.014)^y

b) 5,908

Step-by-step explanation:

Here, we want to write an exponential growth model;

a)The model will be represented as;

P = 5000( 1.014)^y

where P is the population at a particular year after 2010

y is the number of years after 2010

b.) For 2022;

y = 2022-2010 = 12

P = 5000(1.014)^12

P = 5,908 approximately

0.2 is 10 times as much of... well you must do the opposite of what it says... well, times means to multiply and the opposite of multiplying is dividing, 0.2 divided by 10 is 0.02

So... 0.2 is 10 times as much as 0.02

Now, 0.2 is 1/10 of... well this question shows to divide and we must do the opposite, which is... multiplying 0.2 times 10 is 2

So... 0.2 is 1/10 of 2
