The ratio of the longer side of a rectangle to its shorter side is 4 to 3. If the shorter side of the rectangle is 21ft, what is

Eduardwww [97]

Answer:

28 ft

Step-by-step explanation:

Let longer side of rectangle be $L$ and the shorter side be $S$ , thus we can write the ratio:

$\frac{L}{S}=\frac{4}{3}$

<em>Now putting 21 into S, we solve for L:</em>

$\frac{L}{21}=\frac{4}{3}\\3L=4*21\\3L=84\\L=\frac{84}{3}=28$

Hence, length of longer side is 28 ft.

Answer:

-17

Step-by-step explanation:

first find g(5) = -2(5)+5 = -5

then f(-5) = 4(-5)+3 = -17

Peaks are the highest points of a graph, there are four peaks, which are on the line that corresponds with July, which would be summer.

The answers to question 1. are four, four, summer.

January is the lowest point of the graph which are between 0 and 10, so the average temperature for January would be around 5 degrees.

The highest peaks ( July) are around the 70 degree line.

The answer s for question 2 are 5 and 70 degrees.

If sin phi sin theta = 0.2 and sin phi cos theta = -0.3 and sin phi > 0 what is theta ? Repeat for sin phi < 0.

Rina8888 [55]

Answer:

θ = -33.69°

Step-by-step explanation:

For Φ>0 and Φ<0 (in general Φ≠nπ where n is an integer), sin(Φ) ≠ 0

Dividing both equations:

$\frac{sin(\phi) sin(\theta)}{sin(\phi)cos(\theta)} = tan(\theta) = 0.2/(-0.3)=-2/3\\$

Therefore:

arctan(θ) = -2/3

θ = -33.69°

The answer does not depend on the sign of Φ, in fact we just need that the sine does not become zero, which occurs when Φ is equal to an integer times π (radians) or 180 (degrees)

Have a nice day!
