Question 1 (10 points)
Irina18 [472]

Answer:

Q1 d, Q2 c, Q3 d

Step-by-step explanation:

Q1

g(x)=-3x+1

g(x)=16 means that

-3x+1=16 subtract 1 from both sides

-3x=16-1 combine like terms and divide both sides by -3

x=-15/3=-5

Q2

g(x)=3x²+4x-1

g(2) means that x=2 so substitute

g(2)=3*2²+4*2-1=12+8-1=19

Q3

domain are the x values

range are the y values

german

Answer:

17 units

Step-by-step explanation:

Distance between points (a,b)\,,\,(c,d) is given by \sqrt{(c-a)^2+(d-b)^2}

The trail starts at P(−2, 2) and goes to Q(5, 2).

Take (a,b)=(-2,2)\,,\,(c,d)=(5,2)

PQ=\sqrt{(5+2)^2+(2-2)^2}=\sqrt{7^2}=7 units

It goes from Q to R(5, −5)

Take (a,b)=(5,2)\,,\,(c,d)=(5,-5)

QR=\sqrt{(5-5)^2+(-5-2)^2}=\sqrt{(-7)^2}=7 units

It goes from R to S.

Take (a,b)=(5,-5)\,,\,(c,d)=(8,-5)

RS=\sqrt{(8-5)^2+(-5+5)^2}=\sqrt{3^2}=3 units

PQ+QR+RS=7+7+3=17 units

What is the height of a cone whose volume is 16 cubic units and whose radius is 3 units?
erica [24]

Answer:

Square the radius, and then divide the radius squared into the tripled volume. For this example, the radius is 2. The square of 2 is 4, and 300 divided by 4 is 75. Divide the amount calculated in Step 2 by pi, which is an unending math constant that begins 3.14, to calculate the cone's height.

Step-by-step explanation:
