This figure shows circle Z with chords AB and RS . mAR=55° mRB=66° AB=8 m RS=8 m What is mRS?
Alina [70]
M AR = 55°
m RB = 66°
Like AB=8 m =RS →m RS = m AB

m AB = m AR + m RB
m AB = 55° + 66°
m AB = 121°

m RS = m AB
M RS = 121°

Answer: m RS is 121°

Answer:

figure skates will be $1 cheaper.

Explanation:

<u>given equation</u>:

  • to rent figure skates : f(x) = 1.50x + 2
  • to rent hockey skates : h(x) = 2x +1.5

<u>solve for rent of figure skates</u>:

f(x) = 1.50x + 2.00

f(3) = 1.50(3) + 2.00

f(3) = 6.5

<u>solve for rent of hockey skates</u>:

h(x) = 2x + 1.5

h(3) = 2(3) +1.5

h(3) = 7.5

<u>cheaper - figure skates than hockey skates</u>:

$7.5 - $6.5

$1

The population of a culture of cells grows according to the function P(t)= 90t/ t + 1, where t&gt; or =0 is measured in weeks. C
butalik [34]

Answer:

The average rate of change is \frac{18}{5}

Step-by-step explanation:

Given function that shows the population of a culture of cells,

P(t)=\frac{90t}{t+1}------(1)

Where, t represents the number of weeks.

Thus, the average rate of change in the population over the interval [0,24],

m=\frac{P(24)-P(0)}{24-0}

From equation (1),

=\frac{\frac{90\times 24}{24+1}-\frac{90\times 0}{0+1}}{24}

=\frac{\frac{2160}{25}-\frac{0+1}{0}}{24}

=\frac{2160}{25\times 24}

=\frac{2160}{600}

=\frac{18}{5}
