For the vectors u and v with magnitudes u = 88 and v = 99, find the angle θ between u and v which makes u and v = 77.

WARRIOR [948]

Answer:

Step-by-step explanation:

Using the vector formula $u.v = |u||v|cos\theta$

|u| = magnitude of vector u

|v| = magnitude of vector v

u.v is the dot product of vector u and v

Given |u| = 88, |v| = 99 and u.v = 77, to get $\theta$ we will substitute the given values into the equation above;

$77 = 88*99cos\theta\\cos\theta = \frac{77}{88*99} \\cos\theta = \frac{77}{8712} \\cos\theta = 0.008838\\\theta = cos^{-1} 0.008838\\\theta = 89.5^{0}$

Peter spent half the money on his gift card and coffee and he loaded another $10 on the gift card how much was on the gift card

cestrela7 [59]

Answer:

$80 was on the gift card to begin with

Step-by-step explanation:

Let the initial money be x

Peter spent (1/2)*x

Peter added 10

Before adding more money on the gift card Peter had x -(1/2)x left on the gift card which is (1/2)x

After loading more money Peter had (1/2)x + 10

(1/2)x = 40 (money spent by Peter)

x/2 = 40

x = 80

Are the functions inverse of each other? f(x)=5x^2+3, g(x)sqrt x-3/5

luda_lava [24]

Answer:

No.

Step-by-step explanation:

Plugging in g(x) into f(x), you don't get x. g(x) would need to be = $\sqrt{x\frac{-3}{5} }$
