What is the equation in vertex form of the quadratic function with a vertex at (-1,-4) that goes through (1,8)?​
notsponge [240]

Answer:

G

Step-by-step explanation:

vertex formula = a(x-h)^2 + k

vertex is (h, k) so (-1, -4) means

y = a(x+1)^2-4

passes through (1, 8) so when x = 1 and y = 8

8 = a(1+1)^2-4 = 4a - 4

4a = 4

a = 1

What is the measure of angle F?
ololo11 [35]

Answer:

Answer = 140

Step-by-step explanation:

360 = 9x + 14x + 4x + 90

360 - 90 = 27x
270 = 27x
x = 270 / 27
x = 10
14 x 10 Angle F

Measure of angle F = 140

Hezekiel runs 1000 m at a rateof 3 minutes per km. how long does he take to run 500 m​
lana66690 [7]

Step-by-step explanation:

1 km = 1000 m

(hence the term "kilo" which means 1000).

so. he runs 1000 m at the rate of 3 minutes per km, that means 3 minutes per 1000 m.

now, we can see the solution already with our eyes.

but let's do it formally :

the rate or ratio between time and distance must be the same for the same speed.

so,

3 min / 1000 m = x min / 500 m

500 m × 3 min / 1000 m = x min

1/2 × 3 min = x min

3/2 = 1.5 min = x min

so, it takes him 1.5 minutes (90 seconds) to run 500 m.

If cot 0= 1.5 find tan 0 a. 1/1.5 b1.5 c.1/3 d.1/4.5= 0.2222
Zepler [3.9K]

Answer:

tan θ = \frac{1}{1.5}

Step-by-step explanation:

We are given that cot θ = 1.5 and cotangent is the cofunction of tangent.

cot θ = \frac{adjacent}{opposite}

tan θ = \frac{opposite}{adjacent}

We can find the answer to tan θ by taking the reciprocal of the answer to cot θ.

cot θ = 1.5

Then, tan θ = \frac{1}{1.5}

Help me with this problem thank youuup.
UkoKoshka [18]

Step-by-step explanation:

it is a linear function, if the change in y is constant in relation to the changes of x.

in other words, if the slope y change/x change is the same for every point.

when we look at the table, we see x changes constantly by +2.

and y changes constantly by -6.

so, the change rate/slope is constantly -6/2 = -3.

and therefore it is a linear function.

the equation looks like (the slope is always the factor of x)

y = -3x + b

b we get by using one of the x,y pairs like 1,4

4 = -3×1 + b = -3 + b

b = 7

so, the full equation is

y = -3x + 7
