Sam Houston's Arms

OLga [1]

Answer:

The length of the statue's arm is 26.22 ft.

Step-by-step explanation:

Let the length of the statue's arm be 'x'.

Given:

Height of statue is, $H=67\ ft$

Height of male is, $h=5\ ft\ 9\ in=5\ ft+\frac{9}{12}\ ft=5+0.75=5.75\ ft$

Length of the male's arm is, $l=27\ in=\frac{27}{12}=2.25\ ft$

Now, as the size of Sam Houston's statue is proportional to that of an adult male, therefore, their heights and arm lengths will also be in proportion. So,

$\frac{H}{h}=\frac{x}{l}\\x=\frac{H}{h}\times l$

Now, plug in the given values and solve for 'x'.

$x=\frac{67}{5.75}\times 2.25\\x=26.22\ ft$

Therefore, the length of the statue's arm is 26.22 ft

given that sin theta= 1/4, 0 is less than theta but less than pi/2, what is the exact value of cos theta

lapo4ka [179]

Answer:

$\cos{\theta} = \frac{\sqrt{15}}{4}$

Step-by-step explanation:

For any angle $\theta$ , we have that:

$(\sin{\theta})^{2} + (\cos{\theta})^{2} = 1$

Quadrant:

$0 \leq \theta \leq \frac{\pi}{2}$ means that $\theta$ is in the first quadrant. This means that both the sine and the cosine have positive values.

Find the cosine:

$(\sin{\theta})^{2} + (\cos{\theta})^{2} = 1$

$(\frac{1}{4})^{2} + (\cos{\theta})^{2} = 1$

$\frac{1}{16} + (\cos{\theta})^{2} = 1$

$(\cos{\theta})^{2} = 1 - \frac{1}{16}$

$(\cos{\theta})^{2} = \frac{16-1}{16}$

$(\cos{\theta})^{2} = \frac{15}{16}$

$\cos{\theta} = \pm \sqrt{\frac{15}{16}}$

Since the angle is in the first quadrant, the cosine is positive.

$\cos{\theta} = \frac{\sqrt{15}}{4}$

Check out if I'm right Plz explain..if u have a different answer

Ronch [10]

Answer:

A C

Step-by-step explanation:

A

A is true.The numerator does have 3 terms. The constant term (the 3 at the end) is still a term and counts as a term.

B

A constant term does not count as a coefficient so b is not right, just as you have indicated by not underlining it.

C

C is true. In fact, 2 is the leading coefficent of the denominator.

D

Either A is true or D is, but I don't think they both are. You need a modifier to claim that D is true. If the statement said the numerator has at least 2 terms then both A and D would be true. Without the at least, you have to pick one and the one I choose is A

E

This is the tough one. Very sticky. You would think it is true, but it isn't. A constant term is not a coefficient. Coefficients only count when they are with "x"s.

Please help me solve this

In-s [12.5K]

Step-by-step explanation:

Erase the dot points you already have. We are supposed to substitute those values in the right side of problem 1 into the function as x.

For example if x=-4

$- ( - 4) + 5 = 9$

If x=-2

$- ( - 2) + 5 = 7$

If x=0

$0 + 5 = 5$

$- 2 + 5 = 3$

$- 4 + 5 = 1$

So our point should be

-4,9

-2,7

0,5

-2,3

-4,1.

The range is all possible y values in a function. Since this is discrete and we are given the domain, our range will just be the y value of the points you graphed.

(9,7,5,3,1)
