Identify the vertex of g(x) = (x+10)^2+2

RoseWind [281]

Answer:

(-10, 2)

Step-by-step explanation:

Compare:

g(x) = (x+10)^2+2

f(x) = (x - h)^2 + k

Matching these up, term by term, we see that h = -10 and k = 2. (h, k) represents the vertex of the parabola f(x) = (x - h)^2 + k.

We conclude that the vertex of this parabola is (-10, 2).

Need to find the direction angle for each vector. #10 and #12 please!

crimeas [40]

Answer:

10) - 45 degrees

12) 0 degrees

Step-by-step explanation:

10)

Find the x and y components that define the vector that joins C with D:

x-component: -4 - (-8) = - 4 + 8 = 4

y-component: 4 - 8 = -4

use the tangent function to find the angle $\theta$ :

$tan(\theta)=\frac{y-comp}{x-comp}=\frac{-4}{4} = -1\\\theta = -45^o$

12)

Find the x and y components that define the vector that joins A with B:

x-component: 7 - 4 = 3

y-component: - 1 - (-1) = -1 + 1 = 0

use the tangent function to find the angle $\theta$ :

$tan(\theta)=\frac{y-comp}{x-comp}=\frac{0}{3} = 0\\\theta = 0^o$

Is this a true statement? 0.3711 > 0.3801

disa [49]

NO. It's FALSE.

$0.\ 3\ 7\ 1\ 1\\||\ ||\wedge\\0.\ 3\ 8$

therefore 0.3801 > 0.3711

Find the sine of ∠U. A)48/55 B)48/73 C)55/48 D)55/73

charle [14.2K]

Answer:

D) 55/73

Step-by-step explanation:

The question is on trigonometry. Sine of an angle is obtained using the SOH of SOHCAHTOA formula of trigonometry. SOH is an acronym for sine, opposite and hypotenuse. Sine of an angle is obtained from the ratio of opposite and hypotenuse of a given triangle. Thus, SOH

is denoted as stated below.

$sine \: \beta = \frac{opposite}{hypotenuse}$

Hence, given the above triangle,

$sine \: of \: angle \: u = \frac{ |bc| }{ |ab| } = \frac{55}{73}$

Therefore, the sine of angle u = 55/73 (D)
