13. Add 2 on both sides. So you get p/4 =2.8 then multiply by 4 on both sides. This cancels out 4 and leave with p= 11.2

16 first substract 15 from both sides then you will get s/8 =12 then multiply both sides by 8 to leave s by it self 12 times 8 is 96 so s=96

A weight lifter can deadlift 275 pounds. She can increase the weight that she can lift according to the function W(x)=275(1.05)^
suter [353]

Answer:

350.98\ pounds

Step-by-step explanation:

we have

W(x)=275(1.05^{x})

where

W is the weight in pounds

x is the number of training cycles completed

For x=5\ cycles

substitute the value of x in the function

W(5)=275(1.05^{5})=350.98\ pounds

PLEASE HELP.
krek1111 [17]

Answer:

Part a) The radii are segments AC and AD and the tangents are the segments CE and DE

Part b) DE=4\sqrt{10}\ cm

Step-by-step explanation:

Part a)

we know that

A <u>radius</u> is a line from any point on the circumference to the center of the circle

A <u>tangent</u> to a circle is a straight line which touches the circle at only one point. The tangent to a circle is perpendicular to the radius at the point of tangency.

In this problem

The radii are the segments AC and AD

The tangents are the segments CE and DE

Part b)

we know that

radius AC is perpendicular to the tangent CE

radius AD is perpendicular to the tangent DE

CE=DE

Triangle ACE is congruent with triangle ADE

Applying the Pythagoras Theorem

AE^{2}=AC^{2}+CE^{2}

substitute the values and solve for CE

14^{2}=6^{2}+CE^{2}

CE^{2}=14^{2}-6^{2}

CE^{2}=160

CE=\sqrt{160}\ cm

CE=4\sqrt{10}\ cm

remember that

CE=DE

so

DE=4\sqrt{10}\ cm
