Need help with math bell ringer

balandron [24]

Answer:

y = 2

Step-by-step explanation:

Slope that passes through two points, (10, y) and (3, 4) = $m = \frac{y_2 - y_1}{x_2 - x_1}$ .

Where,

$(10, y) = (x_1, y_1)$

$(3, 4) = (x_2, y_2)$

m = -²/7

Plug in the values

$\frac{-2}{7} = \frac{4 - y}{3 - 10}$

$\frac{-2}{7} = \frac{4 - y}{-7}$

Cross multiply

$-2*-7 = 7(4 - y)$

$14 = 28 - 7y$

$7y = 28 - 14$

$7y = 14$

Divide both sides by 7

y = 2

If the sinø=7/12, what is cosø?

777dan777 [17]

Answer:

If the sinø=7/12, cosø is $\frac{\sqrt{95} }{12}$

Step-by-step explanation:

We are given sinФ = 7/12

We need to find cosФ

The basic trigonometric functions of right triangle are:

$sin\theta=\frac{opposite}{hypotenuse}$

$cos\theta=\frac{adjacent}{hypotenuse}$

We need values of adjacent and hypotenuse to find cosФ

Using Pythagoras theorem we can find the value of adjacent

$(Hypotenuse)^2= (Opposite)^2+(Adjacent)^2$

We have Hypotenuse= 12 and Opposite = 7 (because $sin\theta=\frac{opposite}{hypotenuse}$ and we are given $sin\theta=\frac{7}{12}$

Inserting values and finding adjacent:

$(Hypotenuse)^2= (Opposite)^2+(Adjacent)^2\\(12)^2=(7)^2+(Adjacent)^2\\144=49+(Adjacent)^2\\144-49=(Adjacent)^2\\95=(Adjacent)^2\\\sqrt{(Adjacent)^2} =\sqrt{95}\\Adjacent=\sqrt{95}$

So, value of Adjacent is $\sqrt{95}$

Now finding cosФ

$cos\theta=\frac{adjacent}{hypotenuse}$

Adjacent = $\sqrt{95}$ , hypotenuse = 12

$cos\theta=\frac{\sqrt{95} }{12}$

So, If the sinø=7/12, cosø is $\frac{\sqrt{95} }{12}$

(The answer I put is the wrong answer)

ra1l [238]

Answer:

Step-by-step explanation:

Volume = πr²h/3 = πr²9/3 = 3πr²

3πr² = 3πy² + 30πy + 75π

r² = y² + 10y + 25

r² = (y+5)²

r = y+5
