In Exercise, solve the equation for k. <br> 22 = 32e-0.02k
lesya692 [45]

Answer:

18.6

Step-by-step explanation:

We are given that

22=32e^{-0.02k}

We have to find the value of k.

Divide by 32 on both sides then we get

\frac{22}{32}=e^{-0.02k}

\frac{11}{16}=e^{-0.02k}

Taking ln on both sides then we get

ln\frac{11}{16}=-0.02k

lne=1

ln11-ln16=-0.02k

log\frac{m}{n}=logm-logn

2.398-2.77=-0.02k

-0.372=-0.02k

k=\frac{-0.372}{-0.02}=18.6

Hence, the value of k=18.6

In ΔLMN, the measure of ∠N=90°, the measure of ∠M=70°, and NL = 74 feet. Find the length of MN to the nearest tenth of a foot.
Zina [86]

Answer:26.9 feet

Step-by-step explanation:

SOH-CAH-TOA

\tan M = \frac{\text{opposite}}{\text{adjacent}}=\frac{74}{x}

tanM=

adjacent

opposite

​

=

x

74

​

\tan 70=\frac{74}{x}

tan70=

x

74

​

x\tan 70=74

xtan70=74

Cross multiply.

\frac{x\tan 70}{\tan 70}=\frac{74}{\tan 70}

tan70

xtan70

​

=

tan70

74

​

Divide each side by tan 70.

x=\frac{74}{\tan 70}=26.9338\approx 26.9\text{ feet}

x=

tan70

74

​

=26.9338≈26.9 feet

Type into calculator and roundto the nearest tenth of a foot.

Can someone please help me? i hope you can see this omg
Gemiola [76]

Step-by-step explanation:

length = (2x + 3) units

width = (x - 7) units

Area = 2( length × width)

Area = 2( (2x + 3) × (x - 7) )

Area = 2( 2x² - 14x + 3x - 21)

Area = 2 ( 2x² -11x - 21)

Area = 4x² - 22x - 42

Solve for the perimeter and keep it in pi
galben [10]

Answer:

24+6pi

Step-by-step explanation:

the sides on the left and right added up are

12+12=24.

the formula for perimeter of a circle is 2πr.

3 is the radius, making the equation

2π3 which is 6 pi.

for the top semicircle, the perimeter would be 6 pi divided by 2 because its a semicircle.

the bottom cut out half would also be 3 pi.

in total, we would have 24+3pi+3pi which would lead you to 24+6pi.
