For what values of t, if any, is given vector parallel to vector u = (4,-1): (8t, 2t)? and (1,t^2)?

1 answer:

3 0

The vector would have to be a scalar of (4,-1) in order to be parallel to it
so
4 = 8t -1 = 2t

t= 4/8 = 1/2
-1=2t
t= -1/2

A ramp leading into a building makes a 15 degree angle with the ground. The end of the ramp is 10 feet from the base of the buil

stiks02 [169]

Answer:

The length of the ramp is x = AC = 10.35 feet

Step-by-step explanation:

From the ΔABC

AC = x = length of ramp

BC = 10 feet

$\theta = 15$ °

$\cos 15 = \frac{BC}{AC}$

$\cos 15 = \frac{10}{x}$

x = 10.35 feet

Therefore the length of the ramp is x = AC = 10.35 feet

gogolik [260]

Answer:

120

Step-by-step explanation:

Let g = number of girls.

(2/3)g is 2/3 the number of girls

(2/3)g + 35 is 35 more than 2/3 the number of girls. This is the number of boys.

(2/3)g + 35 = 115

(2/3)g = 80

(3/2)(2/3)g = 80(3/2)

g = 120
