1/4 times 8/8 what is the answer to this problem

Which of the following is true about the function y= 4 * 3tothepowerofx

xenn [34]

Only true statement for function f(x) = $4(3^{x})$ is c. if the value of x increases by 1, the value of y will triple.

Step-by-step explanation:

a. the function decreases

f(x) = $4(3^{x})$ , For value of x<1 function decreases and for x>1 function increases . False statement .

c. if the value of x increases by 1, the value of y will triple.

For value of x increases by 1 we have , $f(x) = 4(3^{x+1}) = 4(3^{x})(3) = f(x) (3) = y(3)$ . True statement.

b. the function has a y-intercept of (0, 3)

At y intercept x=0, f(x) = $4(3^{x})$ , $f(0) = 4(3^{0}) = 4$ . Function has a y-intercept of (0,3). False statement.

d. the function contains the point (1, 4)

At x=1, $f(1) = 4(3^{1}) = 12$ . Function contains (1,12) not (1,4) . False statement.

Answer:

100 cm²

Step-by-step explanation:

Area of the larger circle:

A = π(2r)² = 4πr²

The shaded area:

π(2r)² - πr² = 75
3πr² = 75
πr² = 25

Area of the larger circle:

A = 4(25) = 100 cm²

ivann1987 [24]

If you are talking about the area and perimeter of one of the triangular faces...
8 x 1.2 = 9.6
6 x 1.2 = 7.2

Perimeter = 9.6 + 7.2 + 7.2 = 24
Area = Linear Scale Factor²
1.2² = 1.44
7 x 1.44 = 10.08 (units)²

Tickets for a play cost $3 for children and $10 for adults. A group of 25 people paid a total of $201 for tickets to the play. H

lidiya [134]

Answer: There were 7 children

Step-by-step explanation:

Let's use x to represent the children and y to represent the adults.

We know they combine to make a group of 25 people so x+y=25

We also know that they paid $201 and that there is $3 per child and $10 for adults so 3x+10y=201

I will solve by substitution.

Solve for y in the first equation

$x+y=25\\x-x+y=25-x\\y=25-x$

Sub in our value for y into the other equation and solve for x

$3x+10y=201\\3x+10(25-x)=201$

Step 1) Simplify

$3x+250-10x=201\\-7x+250=201$

Step 2) Subtract 250 from both sides

$-7x+250-250=201-250\\-7x=-49$

Step 3) Divide both sides by -7

$\frac{-7x}{-7} =\frac{-49}{-7}\\x=7$

Is (3,-1) a solution of the graphed system of inequalities?

xeze [42]

Yes, (3,-1) is a solution to the graphed system of inequalities.

<h3>What are system of inequalities?</h3>

When mathematical expressions are compared, with non-strict equality, then such mathematical statements are called mathematical inequalties.

A collection of inequalities for which we consider a common solution for all inequalities is called a system of inequalities.

As we can see in the graph that the two lines are interest in the second quadrant at point such as(x, -y).

So, the point will be a solution also because it lies in the shaded region.

Therefore, Yes, (3,-1) is a solution to the graphed system of inequalities.
