Evaluate (f-g)(2)=?

Let f(x)=2x^2+8
g(x)=x-3

Answers

Answer 1

Answer:

[tex]\huge\boxed{(f-g)(2)=17}[/tex]

Step-by-step explanation:

[tex](f-g)(x)=f(x)-g(x)\\\\f(x)=2x^2+8;\ g(x)=x-3\\\\(f-g)(2)=f(2)-g(2)\\\\f(2)\ [g(2)]-\text{substitute}\ x=2\ \text{to}\ f(x)\ [g(x)]\\\\f(2)=2(2^2)+8=2(4)+8=8+8=16\\g(2)=2-3=-1\\\\(f-g)(2)=16-(-1)=16+1=17[/tex]

The Navy Pier Ferris Wheel in Chicago has a circumference that is ​56% of the circumference of the first Ferris wheel built in 1893. The Circumfrence of the Navy Peir wheel is 439.6 ft. What is the radius of the first ferris wheel?

Answers

Hey there! I'm happy to help!

439.6 is 56% of the first Ferris wheel. The word is means equals, so we can set up the following equation. We will call the original wheel w.

439.6=0.56w

We divide both sides by 0.56

w=785

We divide by 3.14 to find the diameter.

785/3.14=250

Radius is half of the diameter.

250/2=125

The radius of the first Ferris wheel is 125 ft.

Have a wonderful day! :D

Step-by-step explanation:

439.6=0.56w

We divide both sides by 0.56

w=785

We divide by 3.14 to find the diameter.

785/3.14=250

Radius is half of the diameter.

250/2=125

The radius of the first Ferris wheel is 125

125ft.

Sosa received $90 in gift cards to Coffee Crazee and each drink she purchases costs $4.75. Sosa also received $75 in gift cards to Fran's Frappes and each drink she purchases cost $3.25. How many drinks will Sosa have to purchase in order to have the same amount remaining on the gift cards from both shops? * 33

Answers

Answer:

90 -4.75x = 75 -3.25x

90-75= 4.75x-3.25x

x= 10

Step-by-step explanation:

Answer:

10 drinks

Step-by-step explanation:

We can set up an equation to find the amount of drinks needed, x.

[tex]90-4.75x = 75-3.25x[/tex]

Now let’s solve for x by isolating it on one side of the equation.

Subtract 75 from both sides:

[tex]15 - 4.75x = -3.25x[/tex]

Add 3.25x to both sides:

[tex]15-1.5x=0[/tex]

Add 1.5x to both sides:

[tex]15 = 1.5x[/tex]

Divide both sides by 1.5:

[tex]x = 10[/tex]

. Given HI=2x,HI=2x, HJ=4x,HJ=4x, and IJ=4x-10,IJ=4x−10, determine the numerical length of \overline{IJ}.
IJ
.

Answers

Answer:

IJ = 20

Step-by-step explanation:

Point I is on the lines segment HJ. So,

HJ = HI + IJ

Putting all the given values, we get :

4x=2x+4x-10

Taking like terms together, we get :

-2x=-10

x=5

Put the value of x in IJ = 4x-10

IJ = 4(5)-10

IJ = 20

Hence, the value of IJ is 20.

Find the volume of the sphere. Use 3.14 for it. Round to the tenths if necessary. Don't forget to include your
label in the answer. Use ^ to show an exponent.

Answers

Hey there! I'm happy to help!

First let's find the radius. The radius is half of the diameter.

9/2=4.5

Here's how to find the volume of any sphere.

You cube the radius.

4.5³=91.125

You multiply by 3.14

91.125(3.14)=286.1325

And finally we multiply by 4/3.

286.1325(4/3)=381.51

We round to the nearest tenth, giving us a volume of 381.5 in^3.

∠A and \angle B∠B are vertical angles. If m\angle A=(3x+3)^{\circ}∠A=(3x+3) ∘ and m\angle B=(4x-8)^{\circ}∠B=(4x−8) ∘ , then find the value of x.

Answers

Answer:

The value of x is 11 degrees

Step-by-step explanation:

Here, given that two angles are vertical angles, we are interested in calculating the value of x. We simply want to use an important property of vertical angles to get the value of x as given in the question.

When we talk of vertical angles, they are angles which lies on opposite side to each other when we have two intersecting line.

By property, vertically opposite angles are equal.

Thus, in this case, we are to equate the angles we are having since they are both vertical angles;

Thus,

Mathematically;

angle A = angle B

3x + 3 = 4x -8

Collect like terms;

4x-3x = 3 + 8

x = 11 degrees
