This question is difficult to give a definite answer to because it's an approximation, but I estimate the solutions to be around x = 2.6 and x = -2.6.

When they ask for solutions of the graphed function they are asking for an approximation of where the graph intercepts the x-axis, and we can see it kind of intercepts in the middle of 2 and 3, except slightly closer to 3, which is why I estimated 2.6.

The graph also appears to be symmetrical, which means the solutions will be the same except one would be negative and one would be positive, which means the second solution would be -2.6.

I hope this helps! Let me know if you have any questions :)

Answer:

a, c

Step-by-step explanation:

Let's start with one of each choice. That'll be 3 * 4 * 3 * 3 * 10 = 1080 pizzas. As for the second one, this time the toppings won't be 10 it will be 10 * 9 * 8 because we have 10, and then 9, and then 8 topping choices. This gives us 1080 * 9 * 8 = 77,760. Hope this helps!

Answer:

Step-by-step explanation:

Well, we can multiply the choices that they gave us, which is 3 by 4 by 3 by 3 by 10, which will give 1080 for the first part. Now, if you was to do only 3 toppings, it should be 3 by 4 by 3 by 3 by 3, which would give us 324. I don't know if this is right but I think this is the right answer.

Answer:

$25,695

Step-by-step explanation:

You can calculate the price of the car in 2000 using the formula to calculate the future value:

FV=PV(1+r)^n

FV= future value

PV= Present value: $7,500

i= rate: 5.5%

n= number of years: 2000-1977= 23

FV= 7,500*(1+0.055)^23

FV= 7,500*(1.055)^23

FV= 7,500*3.426

FV= 25,695

According to this, the approximate value of the car at the time of the auction is $25,695.

Answer:

3. Sides: Equilateral

Angles: Acute

4. Sides: Isosceles

Angles: Right

Step-by-step explanation:

3. Sides: Equilateral because in an equilateral triangle all sides are equal.

Angles: Acute because in an acute triangle all angles are acute.

4. Sides: Isosceles because in an isosceles triangle two legs are equal.

Angles: Right because in a right triangle, one angle is right.

So x =4

Answer:

Jeep value after six years is $11,327.9

Step-by-step explanation:

To find the value of depreciation, we use the exponential function below;

V = I(1-r)^t

where V is the future value of the Jeep which we are to calculate

I is the initial value of the jeep which is $28,000

r is the rate of decrease or depreciation which is 14% or simply 14/100 = 0.14

t is time which is 6 years

Plugging these values into the equation, we have;

V = 28,000(1-0.14)^6

V =28,000(0.86)^6

V = 11,327.88

To the nearest cent; V = $11,327.9

Base area=108 square feet

V=BH=(108)(20)=2160 cubic feet.

Answer:

A

Step-by-step explanation:

The Fundamental theorem of algebra tells us that a polynomial of degree n has n roots.

Here the polynomial is a cubic, that is of degree 3

Thus it will have 3 roots, real and/ or imaginary.

Since imaginary roots occur in conjugate pairs

Since the polynomial has 3 real roots there are no imaginary roots, thus

A is the required response.

Answer:

20% candy contains caramel.

Step-by-step explanation:

A bag of mixed candy has chocolate bars = 25%

and other filler candy = 75%

Let the 'c' represents the percentage of candy containing caramel in the bag of mixed candy.

Of the chocolate bars, percentage of candy containing caramel = 50% of 25%

Of the other filler candy, percentage of caramel candy = 10% of 75%

1c = 0.50(0.25) + 0.10(0.75)

   = 0.125 + 0.075

   = 0.2

By converting into percentage = 0.2 × 100 = 20%

20% candy contains caramel.

Step-by-step explanation:

We don't have Adrian's batting data, but we can find Marlon's ratio thorugh dividing the hits by the total bats.

[tex]M=\frac{6}{15}=0.4[/tex]

Therefore, Marlon has a 40% of hits, which means Adrian needs more than 40% to be better.

Answer:

In this case we can propose a rule of three:

$ 18 ---------------> 100%

x --------------------> 25%

Where x represents the discount made to the pillow:

So we have the new price (with the discount) is:

In addition, if 25% is discounted we have to, the price of the pillow is 75% of the original price. That is to say:

Step-by-step explanation:

Answer :

a= $4.50

b= $13.50

Step by step explanation: 1- find 25% of 18 which is 4.50. 2- subtract 18-4.50= 13.50

Answer:

Step-by-step explanation:

For Case -1

[tex]\Rightarrow -4x+3y=-5\quad \ldots(i)[/tex]

[tex]\Rightarrow 4x-5y=3[/tex]

[tex]\Rightarrow 4x=5y+3[/tex]

Put the value of [tex]4x[/tex] in equation [tex](i)[/tex] we get

[tex]\Rightarrow -(5y+3)+3y=-5[/tex]

[tex]\Rightarrow -5y+3y-3=-5[/tex]

[tex]\Rightarrow 2=2y[/tex]

[tex]\Rightarrow y=1[/tex]

and thus [tex]4x=5(1)+3[/tex]

[tex]x=\frac{8}{4}=2[/tex]

Case-2

[tex]10x-6y=12\quad \ldots(i)[/tex]

[tex]2x+3y=12\quad \ldots(ii)[/tex]

Now multiply [tex](ii) by 5 and subtract it from (i)[/tex]

[tex] 10x-6y=12[/tex]

[tex] 10x+15y=+180[/tex]

[tex]\cdots \cdots \cdots[/tex]

[tex]-21y=-168[/tex]

[tex]y=8[/tex]

and [tex]=6[/tex]

Answer:

Step-by-step explanation:

The Salsa jar has a cylindrical shape. We would determine the volume of Salsa that the jar normally contains and the volume left in the jar by applying the formula for determining the volume of a cylinder which is expressed as

Volume = πr²h

Where

r = radius

π = 3.14

For normal volume,

h = 10 cm

r = 5 cm

Volume = π × 5 × 10 = 50π cm³

For volume left,

h = 4cm

Volume = π × 5 × 4 = 20πcm³

Missing volume = 50πcm³ - 20πcm³ = 30π cm³ = 30 × 3.14 = 94.2 cm³

Answer:

5c+2

Step-by-step explanation:

Not sure the steps

The formula for Douglas' winning percentage is 5c + 2.

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

Given, Douglas and Jesse play video games together. Douglas won two more than five times the number of games that Jesse won.

Since "c" represents the number of games Jesse won

Number of games Douglas won = 5c + 2

Therefore, an expression for the number of games Douglas won is 5c + 2.
