Answer:

C.3

Step-by-step explanation:

We are given that

f(w) varies inversely with w.

f(w)=0.75 when w=8

We have to find the value of f(w) when w=2

According to question

f(w)\propto\frac{1}{w}

f(w)=\frac{k}{w}

Where k=proportionality constant

Substitute the given values then, we get

0.75=\frac{k}{8}

k=0.75\times 8

k=6

Substitute the value of k then, we get

f(w)=\frac{6}{w}

Substitute the value of w=2

Then, we get

f(w)=\frac{6}{2}=3

f(w)=3

Hence, option C is true.

6. Multiply: i) 3x (5x+8y)
Stella [2.4K]

Answer:

Step-by-step explanation:

3x(5x+8y)=15x^2+24xy

4x(3x^2+5x-7)=12x^3+20x^2-28x

(3x+4y)(2x-7y)=6x^2+8xy-21xy-28y^2=6x^2-13xy-28y^2

(2-3a)(2a^2-3a+7)=4a^2-6a+14-6a^3+9a^2-21a=-6a^3+13a^2-27a+14

Hi! I have a question and I don't understand it's answer. Could you help me?It's in the attachment below.
Paladinen [302]

To solve this question, we just need to evaluate our set of points in the standard form equation of a Hyperbola, and find the coefficients. This will give to us the equation for our Hyperbola. The standard form is

\frac{(x-h)^2}{a^2}-\frac{(y-k)^2}{b^2}=1

Let's start with the easier points, the x-intercepts (5, 0) and (-1, 0).

Since this hyperbola has two x-intercepts, we're dealing with a horizontal hyperbola, and the center is the midpoint between the x-intercepts.

\begin{gathered} \bar{x}=\frac{x_1+x_2}{2}=\frac{-1+5}{2}=2 \\ \bar{y}=\frac{y_1+y_2}{2}=\frac{0+0}{2}=0 \end{gathered}

The center coordinates are (2, 0), then, our equation is

\frac{(x-2)^2}{a^2}-\frac{y^2}{b^2}=1

To find the missing coefficients, we can just substitute the remaining points and solve the system for a and b. Our final equation is

\frac{(x-2)^2}{9^{}}-\frac{y^2}{4}^{}=1

Help pls I need the angle and the answer pls help this is a quiz grade
Alecsey [184]

Answer: h = 113°

Step-by-step explanation:

First, we will find the third angle of the top triangle

Which we can call x

43° + 24° + x = 180°

67° + x = 180°

x = 180° - 67°

x = 113°

Now, we can see that x and h are opposite angles

Which means x = h

113° = h

A bag of Super Whisker cat food, at $12.85, is one third the price of a bag of Power Meow cat food. Write and solve a division e
allsm [11]

Answer:

Price of power meow cat food = $38.55

Step-by-step explanation:

Price of whisker cat food = $12.85

Price of power meow cat food = x

Whisker cat food = ⅓ * power meow cat food

12.85 = ⅓ x

X = 3 * 12.85

X = $38.55

Price of power meow cat food is $38.55
