What is the value of the function at x = 3?

Enter your answer in the box.

Answer:

The given statement is True

Step-by-step explanation:

WE have to find out that which one has more no of inches

so now we have

100 yards football field

28 meter basketball court

Total no of inches in one yard =  36 inches

Total no of inches in 100 yard = 36 * 100

                                                  = 3600 inches

Now total no of inches in one meter = 39.3701 inches

Total no of inches in 28 meter =  28 * 39.3701

                                                   =1102.3628 inches

So we can see that 1102.3628 is smaller than 3600

So It can also be seen that football field has more inches then a basketball court

So the given statement is True

Answer:

The given statement is true.

Step-by-step explanation:

First we will apply conversions to given terms:

1 yard has = 36 inches

So, 100 yards has = [tex]36\times100=3600[/tex] inches.

1 meter = 100 cm

So, 28 meters has = [tex]28\times100=2800[/tex] cm

So, now upon comparing we can see that 3600 is greater than 2800.

Therefore, the inches in a 100 yard field are greater than the cm in a 28 meter basketball court.

The statement given here is true.

Step-by-step explanation:

It should be a parabola that opens upward and is shifted 2 units downward.

The graph of the quadratic function y = x² - 2 typically looks like.

The graph of the quadratic function y = x² - 2 is a parabola. Specifically, it's a upward-opening parabola because the coefficient of the x² term (which is 1) is positive.

- The vertex of the parabola is at the point (0, -2).

- The parabola opens upward, so it does not intersect or cross the x-axis.

- It reaches its minimum value at the vertex, which is -2.

Answer:

x-intercept = 3 ; y-intercept = -5

Step-by-step explanation:

Lets rearrange the equation into the form y = mx + b:

5x - 3y = 15

-3y = 15 - 5x

Divide by -3:

y = 5x/3 - 5

Here we know that b (-5) is the y-intercept, and we can find the x-intercept by starting at the y-intercept and using the slope till we get the x-intercept. Or you can set y = 0 and solve for x, either way you get x-intercept = 3.

This equation is in standard form, if you put it into slope-intercept form, you will be able to graph it. Once you graph it you will be able to find the intercepts.

5x - 3y = 15

-3y = -5x + 15

y = 5/3x - 5

Answer:

The total cost of one hot dog, one slice of pizza and one ice cream cone at the county fair is $3.

Step-by-step explanation:

Let us assume that the cost of the one hot dogs be x.

Let us assume that the cost of the one ice cream cone be y.

Let us assume that the cost of the one silce of pizza be z.

As given

At the county fair, two hot dogs and an ice cream cone cost $2.50.

Than the equation becomes

2x + y = 2.50

Two slices of pizza and an ice cream cone cost $3.50.

2z + y = 3.50

Than two equations are

2x + y = 2.50 and 2z + y = 3.50

Adding the both above equation.

2x + y +  2z + y = 2.50 + 3.50

2x + 2z + 2y = 6

[tex]x + y + z = \frac{6}{2}[/tex]

x + y + z = 3

Therefore the total cost of one hot dog, one slice of pizza and one ice cream cone at the county fair is $3.

An exponent represents repeated multiplication. For example, ...

... x^3 = x·x·x

... x^2 = x·x

If we divide these, the x's in the denominator cancel an equal number in the numerator:

... (x·x·x)/(x·x) = x

If we represent the repeated multiplication using exponents, we can represent the cancellation by subtraction:

... (x^3)/(x^2) = x^(3-2) = x^1 = x

Once we have this idea in mind that division can be done by subtracting denominator exponents, we can use it regardless of the magnitude or sign of the exponents involved.

Answer:

3 adults and 24 students

Step-by-step explanation:

We can set-up a system of equations to find the number of adults. We know students and adults attended. We will let s be the number of students and a be the number of adults. Since 27 tickets were purchased, then s+a=27.

We also know they were purchased for $60 and adult tickets cost $4 and student tickets cost $2. We can write 2s+4a=60.

We will solve by substituting one equation into the other. We start by solving the first equation for c. s+a=27 becomes s=27-a.

Now we substitute s=27-a into 2s+4a=60. Simplify and isolate the variable a.

2s+4a=60

2(27-a)+4a=60

54-2a+4a=60

54+2a=60

54-54+2a=60-54

2a=6

a=3

This means that 3 adults attended and 24 students attended since 3+24=27.

Step-by-step explanation:

We can use the Exterior Angle of a Triangle theorem to find x. It states that the exterior angle of a triangle is equal to the sum of the two opposite interior angles.

We will start with x+5. It is equal to 79 +____ an angle we don't know yet. But we do know that the angle____ and x equals 180 because they form a straight line. Therefore the unknown angle must be 180-x.

So we will set x+5=79+180-x. We will combine like terms, use inverse operations, and isolate.

x+5=79+180-x

x+5=259-x

x+x+5=259-x+x

2x+5=259

2x+5-5=259-5

2x=254

Final answer:

To find the original price of a pizza before a 20% discount that resulted in a final price of £5.60, divide the final price by 0.8. The original price is calculated to be £7.00.

Explanation:

The question involves determining the original price of a pizza before a 20% discount was applied, given that the reduced price after the discount is £5.60.

To calculate the original price, we can use the formula for finding the original price when the final price and discount rate are known.

Let's denote the original price as OP. Since a 20% discount was applied, the pizza sold for 80% of its original price. The equation representing this situation is:

0.8 × OP = £5.60

Now, we divide the reduced price by 0.8 to find the original price:

OP = £5.60 / 0.8

OP = £7.00

Thus, the original price of the pizza was £7.00 before the 20% discount was applied.

Answer:

angle of elevation to the sun is 15.52°

Step-by-step explanation:

basketball goal 10 ft high casts a shadow 36 ft long

This forms a right angle triangle. the diagram is attached below

We need to find out angle A

We know opposite side = 10ft and adjacent side = 36 ft

We use tan formula

[tex]tan(A) = \frac{opposite}{adjacent}[/tex]

[tex]tan(A) = \frac{10}{36}[/tex]

To find A we move tan to the other side, it becomes tan^-1

[tex]A =tan^{-1}(\frac{10}{36})[/tex]

A = 15.52

So angle of elevation to the sun is 15.52°

c. even likely degree 4

Step-by-step explanation:

A polynomial graph has several features we look for to determine the equations.

In this graph, there are four real zeros: -2,-1,1,2

We can write them in intercept or factored form as (x-2), (x-1), (x+1) and (x+2).

Because the graph crosses the x-axis at -2, it's multiplicity is odd likely 1. This is the same for each of the zeros or x-intercepts.

The graph a W shape and facing upwards so it has a positive leading coefficient with an even degree.

This means the function has a degree of 4 or higher with the degree being even.

The lengths of the sides of triangle DEF are DE = 0.75 cm, EF = 1.125 cm, and DF = 1.5 cm.

Triangles ABC and DEF are similar, which means their corresponding angles are equal. In similar triangles, the ratio of the lengths of corresponding sides is constant. To find the lengths of the sides of DEF, we can use the ratio of the corresponding sides of ABC and DEF.

Let x be the length of DE in triangle DEF. Since DE corresponds to AB, we have the ratio x/2 = 1.5/4, which simplifies to x = 0.75 cm. Similarly, for EF corresponding to BC, y/3 = 1.5/4, giving y = 1.125 cm. Finally, for DF corresponding to CA, z/4 = 1.5/4, yielding z = 1.5 cm.

Therefore, the lengths of the sides of triangle DEF are DE = 0.75 cm, EF = 1.125 cm, and DF = 1.5 cm. This result is consistent with the idea that in similar triangles, the ratio of corresponding sides remains constant.

The calculation involved setting up and solving simple proportions based on the given lengths of the sides of triangle ABC and using them to find the lengths of the sides of triangle DEF.

Answer:

total cost = $ 81

Step-by-step explanation:

It is given that the fixed cost is $ 39

and the cost per minute is $0.07

Let us assume the number of minutes used be x

we have

total cost = cost per minute × number of minutes used  + fixed cost

we plug the given values, so we have

[tex]total cost = 0.07 x+39[/tex]

we need to find the total cost for 10 hours used

x= 10 hours = 10(60) minutes = 600 minutes

so we have total cost for x= 600 minutes

[tex]total cost = 0.07(600)+39[/tex]

[tex]total cost =42+39 = 81[/tex]

hence the total cost = $ 81

Answer: 33 and 28

Step-by-step explanation:

so, all we know is ? + ? = 61

if the larger number is 5 more than the smaller number, we can assume that..

33 + 28 = 61

The mean distance ran by all four of them is 30.

Given is that sum of two numbers is 61 . The larger number is 5 more than the smaller number.

We can write the equations as -

x + y = 61                                               .... Eq{ 1 }

y = x + 5                                                  .... Eq{ 2 }

Now, we can write -

x + y = 61

x + x + 5 = 61

2x = 56

x = 28

and

y = 33

Therefore, the mean distance ran by all four of them is 30.

Height is 18 inches.

Base is 36 inches.

Step-by-step explanation:

Let the base of the triangular table top be x inches.

The height will be [tex]\frac{1}{2}[/tex]x inches.

The area of the triangular table top is 324 inches²

Area of a triangle = [tex]\frac{1}{2}[/tex] × Base × Height

342 inches² = [tex]\frac{1}{2}[/tex] × x × [tex]\frac{1}{2}[/tex]x

[tex]\frac{x^2}{4}[/tex] = 324

Finding the square root on both sides gives;

[tex]\frac{x}{2}[/tex] = 18

Therefore x (the base) = 36 inches

And [tex]\frac{1}{2}[/tex] (the height) = 18 inches.

Final answer:

The height of the triangular table top is 18 inches, and the base is 36 inches, using the formula for the area of a triangle and given that the base is twice the height with an area of 324 square inches.

Explanation:

The question requires finding the height and base of a triangular table top given that the area is 324 square inches and the base is twice as long as the height. To find these dimensions, we can use the formula for the area of a triangle, which is Area (A) = [tex]\frac{1}{2}[/tex] × base (b) × height (h). Given that the base is twice the height, we can express the base as 2h.

Now, we can set up the equation using the given area: 324 = [tex]\frac{1}{2}[/tex] × 2h × h. Simplifying gives us 324 = h², so the height (h) would be the square root of 324, which is 18 inches. The base (2h) is therefore 36 inches. So, the dimensions of the tabletop are a base of 36 inches and a height of 18 inches.

Answer:

yes; you can just remember that all the angles on a triangle equal 180 so just add the two angles, subtract from 180 to get your last angle degrees.
