Help with math homework!
Natalka [10]

Answer:

93\frac{24}{27}

<u>Step-by-step:</u>

86 + 7 = 93

<u>The 24 denominator stays the same and just add the numerators:</u>

\frac{14}{24} + \frac{13}{24}

= 93\frac{24}{27}

*also 14 + 13 does not equal 24, its just closest to one of the choices*

Does the bathroom have enough water and shampoo for 888 long-haired members and 777 short-haired members?
Dovator [93]

Complete question :

Members of the swim team want to wash their hair. The bathroom has less than 5600 liters of water and at most 2.5 liters of shampoo. 70L+ 60S < 5600 represents the number of long-haired members L and short-haired members S who can wash their hair with less than 5600 liters of water. 0.02L + 0.01S < or equal to 2.5 represents the number of long-haired members and short-haired members who can wash their hair with at most 2.5 liters of shampoo. Does the bathroom have enough water and shampoo for 8 long-haired members and 7 short -haired members?

Answer:

Yes , there is enough water and shampoo

Step-by-step explanation:

Given that:

Number of long and short hair member who can wash their hair with less than 5600 litres of water.

70L+ 60S < 5600

Number of long and short hair member who can wash their hair with at most 2.5 litres of shampoo

0.02L + 0.01S ≤ 2.5

To check if bathroom has enough water and shampoo for 8 long haired and 7 short haired members.

Water check:

70L+ 60S < 5600

L = 8 ; S = 7

70(8) + 60(7) < 5600

560 + 420 < 5600

980 < 5600

Inequality constraint is satisfied ; There is enough water.

Shampoo check:

0.02L + 0.01S ≤ 2.5

L = 8 ; S = 7

0.02(8) + 0.01(7) ≤ 2.5

0.16 + 0.07 ≤ 2.5

0.23 ≤ 2.5

Inequality constraint is satisfied ; There is enough shampoo

What are the critical points for g(θ) = 20θ − 5 tan θ
jarptica [38.1K]

g(θ) = 20θ − 5 tan θ

To find out critical points we take first derivative and set it =0

g(θ) = 20θ − 5 tan θ

g'(θ) = 20 − 5 sec^2(θ)

Now we set derivative =0

20 − 5 sec^2(θ)=0

Subtract 20 from both sides

− 5 sec^2(θ)=0 -20

Divide both sides by 5

sec^2(θ)= 4

Take square root on both sides

sec(θ)= -2  and sec(θ)= +2

sec can be written as 1/cos

so sec(θ)= -2  can be written as cos(θ)= -1/2

Using unit circle the value of θ is \frac{2\pi}{3} and\frac{4\pi}{3}

sec(θ)= 2  can be written as cos(θ)=1/2

Using unit circle the value of θ is \frac{\pi}{3}and\frac{5\pi}{3}

For general solution we add 2npi

So critical points are

\frac{2\pi}{3} + 2n\pi,\frac{4\pi}{3} + 2n\pi , \frac{\pi}{3} + 2n\pi, \frac{5\pi}{3} + 2n\pi

On a coordinate plane, an exponential function has a horizontal asymptote of y = 0. The function curves up into the first quadra
aleksandr82 [10.1K]

Answer:

The graph will show an initial value that is lower on the y-axis

Step-by-step explanation:

The exponential function has the next general form:

y = ab^x

where <em>a</em> is the initial amount and <em>b</em> is the base.

If the <em>a</em> value in the function is decreased, but remains greater than 0, the y-intercept of the curve decrease.
