An observer 2.5 miles from the launch pad of a space shuttle measures the angle of elevation to the base of the shuttle to be 25
kotegsom [21]

Answer:

Height of shuttle at that instant  = 1.17 miles

Step-by-step explanation:

Refer the given figure.

C is the position of rocket and B is the position of observer.

Here we need to find AC, that is the height of shuttle at that instant.

Using trigonometric rules on ΔABC, we have

      tan25=\frac{AC}{AB} \\\\tan25=\frac{AC}{2.5}\\\\AC=2.5\times tan25\\\\AC=1.17miles

Height of shuttle at that instant = AC = 1.17 miles

1/2(x+10)= 1/4 (x-8) x= <br> (must be a fraction)
Alex_Xolod [135]

Answer:

x=-9\frac{1}{3}

Step-by-step explanation:

\frac{1}{2}(x+10)=\frac{1}{4}(x-8)

\frac{1}{2}x+5=\frac{1}{4}x-2

\frac{1}{2}x-\frac{1}{4}x=-5-2

\frac{3}{4}x=-7

x=-\frac{28}{3}=-9\frac{1}{3}

Solve 4e^2x-3=12 please help
Anestetic [448]

4*e^{2x} -3 = 12

Step 1:

Here we have -3 in subtraction on the left side, so when we take it to the right we apply opposite operation of subtraction that is addition.

4*e^{2x} = 12+3

4*e^{2x} = 15

Step 2:

Next we have 4 in multiplication on left side, so dividing right side by 4,

e^{2x} = 15/4

e^{2x} = 3.75

Step 3:

taking log on both sides

ln ( e^{2x}) = ln(3.75)

{2x} =ln 3.75

Step 4:

Dividing right side by 2,

x= ln (3.75) /2 = 0.66088

Answer : x = 0.66088..
