This can be solve using trigonometric function. since the given side is the adjecent of the angle which is length of the shadow and the unknown is the side opposite the angle, which is the height of chad.

Tan (a) = opposite / adjacent

Opposite = tan(23) * 14.3 ft

Opposite = 6.1 ft is the hieght of Chad

Answer:

6.1

please give me brainliest!!

Step-by-step explanation:

Imagine right triangle with first leg to be the Chad length and second leg to be the Chad's shadow. Second leg has length 14.3 ft and since the straight-line distance from the top of Chad’s head to the end of the shadow creates a 23° angle with the ground, you could consider the trigonmetric function

tan23 = chad's length/chads shadow length

tan23 = chad's length/14.3

chad's length = 14.3 * tan23 = 6.1

The domain for f(x) and g(x) is the set of all real numbers. Let f(x) = 3x + 5 and g(x) = x2. Find g(x) − f(x).
kifflom [539]

Answer:

3x^2 + 8  

Step-by-step explanation:

Given functions,

f(x) = 3x + 8 ----(1)

g(x) = x^2 -----(2)

Since,

(fog)(x) =  f( g(x) )      ( Composition of functions )

=f(x^2)             ( From equation (2) )

=3x^2 + 8          ( From equation (1) )

Hence,

(fog)(x)=3x^2 + 8

Match the following guess solutions yp for the method of undetermined coefficients with the second-order nonhomogeneous linear e
qaws [65]

Answer:

Step-by-step explanation:

For each of the yp(x) we can deduce the characteristic polynomial of the differential equation

A.

yp(x)=Ax^2+Bx+C\\m^2=0\\y''=0

B.

yp(x)=Ae^{2x}\\(m-2)m=0\\m^2-2m=0\\y''-2y=0

C.

yp(x)=Acos2x+Bsin2x\\m_1=2i\\m_2=-2i\\y''+4=0

D.

yp(x)=(Ax+B)cos2x+(Cx+D)sin2x\\yp(x)=xcos4x

hope this helps!!

A golf association sets performance standards for golf balls. For​ example, the initial velocity of the ball may not exceed 250
Oksanka [162]

Answer:

In this context 38% represents that if the mean speed of ball is 250 ft/sec, then there is 34% chance of obtaining a similar or more extreme value related to test statistics.

Step-by-step explanation:

We are given that the initial velocity of the ball may not exceed 250 feet per second when measured by an apparatus approved by the association.

Based on the mean speed in the​ sample, the association comes up with a​ P-value of 0.38.

Let \mu = <u><em>mean speed of the ball</em></u>

So, Null Hypothesis, H_0 : \mu = 250 ​ft/sec

Alternate Hypothesis, H_A : \mu > 250 ft/sec

Now, the P-value given to us is 0.38.

P-value basically tells us the exact percentage where our test statistics lie. Also, it is the probability of obtaining the value that is more extreme, given that null hypothesis is true,

So, in this context 38% represents that if the mean speed of ball is 250 ft/sec, then there is 34% chance of obtaining a similar or more extreme value related to test statistics.
