AC=2AE ( because diagonal of rhombus bisect each others)

AE=8 cot 53°

AE=6

AC=2 x 6 = 12

Hence, The length of AC is 12

Answer:

The length of <u>AC is 12  </u>

Step-by-step explanation:

we need to find measure of AC

Since, diagonal of rhombus bisect each others at 90°

AC = 2AE

In ΔAEB

Since, cot\theta=\frac{base}{perpendicular}

cot53=\frac{AE}{EB}

Since AE =EB = 8

cot53=\frac{AE}{8}

Multiply both the sides by 8,

AE = 8 cot 53°

AE = 8 * 0.75

AE = 6

so,

AC=2 x AE

AC=2 x 6

AC= 12

Hence, The length of <u>AC is 12  </u>

An object is launched from a platform.
Bess [88]

Answer:

60 feet

Step-by-step explanation:

The height, h (in meters), of the object launched from a platform is represented by the equation

h=h(x)=-5x^2+20x+60

where x is the time (in seconds) passed after the launch.

The time of launch is x=0 (0 seconds passed after the launch)

Substitute x=0 to find the height:

h=h(0)=-5\cdot 0^2+20\cdot 0+60=60\ feet
