Answer:

119 m

Step-by-step explanation:

First find the square 7x7 = 49m

Now the triangle $\frac{5 * 7}{2}$ = 17 .5

17.5 * 4 = 70m

70m + 49m = 119m

Answer:

$x=3.75\ units$

Step-by-step explanation:

we know that

$(AE)(EB)=(CE)(ED)$ ----> by Intersecting Chords Theorem

substitute the given values

$(6)(5)=8x$

solve for x

$x=\frac{30}{8}$

$x=3.75\ units$

Shalnov [3]

Answer:

p value = 0.039

t = - 2.169

Step-by-step explanation:

Applying the null and alternate hypothesis

$H_{0} : U1 = U2$

$H_{\alpha } : U1 \neq U2$

using excel worksheet to calculate for ( t and p )

t = -2.169

p = 0.039

from the results obtained

The conclusion is affected by the significance level because : 0.1 0.01

so when the significance level is = 0.1 the Null hypothesis is rejected and we can say the mean time interval will change while

if the significance level = 0.01 the Null hypothesis is accepted and we can not say the mean time interval has changed because the p -value is greater than 0.01

attached is the excel solution

I don't know how to do this please help explain how to do it aswell as give the answer so i understand

Zinaida [17]

We are given:

The function: y = -16t² + 64

where y is the height from ground, t seconds after falling

Part A:

when the droplet would hit the ground, it's height from the ground will be 0

replacing that in the given function:

0 = -16t² + 64

16t² = 64 [adding 16t² on both sides]

t² = 4 [dividing both sides by 16]

t = 2 seconds [taking square root of both sides]

Part B:

for second droplet,

height from ground = 16 feet

time taken = t seconds

acceleration due to gravity = 10 m/s²

initial velocity = 0 m/s

h = ut + (1/2)at² [second equation of motion]

16 = (0)(t) + (1/2)(10)(t²)

16 = 5t²

t² = 16/5

t = 1.8 seconds (approx)

Therefore, the second droplet takes the least amount time to hit the ground
