Step-by-step explanation:

Suppose that
g(x) = f(x)•h(x),
f(3) = 6,
h(3) = 2,
h'(6)=4,
h'(3)=15 and
f'(3) = 8.
Find g(3).

(A) 32
(C) 106
(B) 8
(D) 60

Answers

Answer:

g(3) = 6*2 = 12

Step-by-step explanation:

In this problem you're given more information than is necessary to solve it.  

g(x) = f(x)*h(x) is the product of functions f and h.

If x has the value 3, then:

f(x) = f(3) = 6, h(x) = h(3) = 2.  Thus, when x = 3 we have g(x) = g(3) = 6*2 = 12

The value of g(3) using g(x) = f(x)·h(x) is 12.

Given that, g(x) = f(x)·h(x).

What is the function?

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

Put x=3 in g(x) = f(x)·h(x), we get

g(3) = f(3)·h(3)

⇒ g(3) =6×2

= 12

Therefore, the value of g(3) using g(x) = f(x)·h(x) is 12.

Write an expression that is equivalent to 1/2a - 4

Answers

The expression that is equivalent to 1/2a - 4 is 1/2 (a - 16)

Given the expression 1/2a - 8, to get the equivalent expression, we will factor out 1/2 from the expression to have:

1/2 (a - 8 (2))

Note that we will need to multiply the second term by the denominator of the fraction to neutralize the fraction.

Simplify to have:

1/2 (x - 8 (2))1/2 (x - 16)

Hence the expression that is equivalent to 1/2a - 4 is 1/2 (a - 16)

The ratio of brown tiles to white tiles in Mrs.Harris kitchen in 4 to 5. There are 180 white tiles in the kitchen. What is the total number of tiles in mrs. Harris kitchen

Answers

Answer:

405

Step-by-step explanation:

Don't be confused about setting up the proportion. White has to go with white which is 4 and brown goes with 5.

The total is 9.

so proportion will look like this.

4/9 = 180/x          Cross Multiply

Before I solve this, notice that the white data is on top of the fraction, and the total is on the bottom of the fraction on either side of the proportion.

4x = 180 * 9

4x = 1620

x = 1620 / 4

x = 4 0 5

Notice that the brown is going to be bigger than the white but not by much

White                            180

Brown       405 - 180 = 225

Total                              405

Write an equation in slope-intercept form of the line shown.

Answers

Answer:

Step-by-step explanation:

y2-y1/x2-x1

1+3

3-1

your slope is 4/2 or 2. keep going down to find what y is when x is 0, which happens to be -5

so now you have a slope and a y intercept you can solve  like y=mx+b where m is your slope and B is your y intercept

y=2x-5 is your answer

it’s y=2x-5 because if you go down to see where the y intercept is which is where the line meets the y axis (the vertical axis) which is on 0,-5 which would be the b i think in y=mx+b

Answers

Answer: it’s 35 mi/h

Step-by-step explanation:  

The constant speed is 35 miles per hour. Therefore, option C is the correct answer.

What is the speed?

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

The slope of rate of change of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

From the graph,

Constant speed = 35 miles/1 hour

= 35 miles per hour

Therefore, option C is the correct answer.

what is 5/6 rounded to the nearest hundredth?

Answer:

0.83

First, we convert the fraction to a decimal number by dividing the numerator by the denominator:

5 / 6 = 0.833

There are two parts to the decimal number above:

Integer Part: 0

Fractional Part: 833

Now, we will make the Fractional Part just two digits (nearest hundredth) by using our rounding rules.*

In this case, Rule I applies, so 5/6 (or 0.833) rounded to the nearest hundredth in decimal format is:

Only one color, but not one size,

What is it?

Answers

Answer:

The first riddle is Age. Some people love their age, some people hate their age. Age can change appearances and thoughts because as you mature you view things differently. If you take care of yourself, you will become die older than most people. Some people are fooled by age, they think someone is older or younger than they really are. Some people don't know someone's age, so it is a mystery. Some people try and hide their age. Age never decreases.

The second riddle is a shadow. A shadow is only one color, but it can be any shape or size. Shadows are stuck at the bottom, but it easily moves. Shadows appear in the sun, but not when it is raining because of the clouds. Shadows do no harm, and they can't feel anything.

Answer and Step-by-step explanation:

A. 4 inches: An object that's 4 inches is about 2.54 centimeters or 25.4 millimeters. An business envelope is typically about 4 inches by 9 inches for example.

Answer:

40.9 ft

Step-by-step explanation:

Perimeter is the sum of lengths of all outer sides of the shape. Since the rectangle has two pairs of parallel lines of the same length... It is safe to assume that the unmarked side length is 10 ft (just like it's parallel counterpart)

Now it is a simple matter of adding all of the outer sides.

8ft + 10 ft + 10 ft + 8.9 ft + 4 ft = 40.9 ft

Margie bought 1 1/2
pounds of tomatoes for $2.00 per pound,
1/4 pound of onions for $1.60 per pound, and 1 pound of apples for $1.65 per pound. How much did she pay for her total purchase?

Answers

Answer:

She spent $5.05 for her total purchase.

Step-by-step explanation:

First, you should convert the fractions into decimals to make it easier, which would make it, 1.5, .25, 1.

Second, multiply 1.5 by 2 because there are 1.5 pounds which are payed for $2.00. Do the others fractions corresponding with the number of pounds and the cost this same way. 1.5 multiplied by 2 is 3. .25 multiplied by 1.60 is 0.4, 1 multiplied by 1.65 is 1.65.

Lastly, Add it all up, 3+0.4+1.65=5.05

Pablo mixes 3 units white paint and 1 unit black paint to make gray paint. What two equations show the relationship between units of white paint, w, and units of black paint, b? Show your work.

Answers

Answer:

[tex]w = \frac{1}{3}b[/tex] and [tex]b = 3w[/tex]

Step-by-step explanation:

Represent white paint with w and black with b

Given

When w = 3; b = 1

Required

Determine the two equations

To get a gray paint, the w and b are needed in the following proportion:

[tex]3 * w = 1 * b[/tex] -----(1)

Solve for b

[tex]3 * w = b[/tex]

Reorder

[tex]b = 3 * w[/tex]

[tex]b = 3w[/tex] ---- This is an equation

To get another equation,

Recall that

[tex]3 * w = 1 * b[/tex]

Solve for w

[tex]3*w = b[/tex]

[tex]3w = b[/tex]

Make w the subject

[tex]w = \frac{1}{3}b[/tex]

Hence, the equations that show the relationship between w and b are:

[tex]w = \frac{1}{3}b[/tex] and [tex]b = 3w[/tex]
