For the function f(x) = x^2 range will be { 4 , 16 , 68 , 81 }

Given that:

[tex]\text {Function is } f(x)=x^{2}[/tex]

Domain of the function is {-2, 4, 8, 9}

Need to determine range of the function.

Domain of the function is possible input of the function that is x and range of the function is possible output of the function that is f(x)  

As there are only four input values for x that are -2,4,8,9 we can determine the range by calculating value of f(x) for each of the x

[tex]\begin{array}{l}{\text {At } x=-2:} \\\\ {f(x)=f(-2)=-2^{2}=4}\end{array}[/tex]

[tex]\begin{array}{l}{\text {At } x=4:} \\\\ {f(x)=f(4)=4^{2}=16}\end{array}[/tex]

[tex]\begin{array}{l}{\text {At } x=8:} \\\\ {f(x)=f(8)=8^{2}=64} \\\\ {\text {At } x=9:} \\\\ {f(x)=f(9)=9^{2}=81}\end{array}[/tex]

Thus the range of given function is { 4 , 16 , 68 , 81 }

Answer:

D)24 people

Step-by-step explanation:

Total number of people, x=300

Number of people donated blood with type A, y

[tex]=\frac{28}{100}\times x\\=\frac{28}{100} \times 300\\=84[/tex]

Number of people donated blood with type B, z

[tex]=\frac{20}{100}\times x\\=\frac{20}{100} \times 300\\=60[/tex]

⇒Number of people with Type A blood donated more than those with Type B blood= y-z=84-60= 24

Answer:

D) There are 24 more people who donated Type - A then Type -B.

Step-by-step explanation:

Total number of people who donated the blood in shelter = 300

Percentage of people who donated the type A = 28%

Percentage of people who donated the type B = 20%

Now, 28 %  of 300 = [tex]\frac{28}{100 } \times 300 = 84[/tex]

So, the total number of people who donated the Type - A  = 84 people.

Also, 20 %  of 300 = [tex]\frac{20}{100 } \times 300 = 60[/tex]

So, the total number of people who donated the Type - B  = 60 people.

So, the difference in the people who donated type A and Type B  

= Number of people who donated the {Type - A  - Type - B}

= 84 people -  60 people

= 24 people

or, the difference in the people who donated type A and Type B  = 24

Hence, there are 24 more people who donated Type - A then Type -B.

To solve the expression, rewrite each term with the same denominator and then add them together. The final answer is 2.345.

To solve the expression 1 15/100 +1/50 +1.175, we need to rewrite all the terms with the same denominator. The least common denominator (LCD) of 100 and 50 is 100. Therefore, we can rewrite the expression as follows:

1 15/100 is equivalent to 1.15

1/50 is equivalent to 0.02

Now, we can add the three terms together:
1.15 + 0.02 + 1.175 = 2.345

Answer:

The restaurant sold 175 hotdogs and 525 hamburgers.

Step-by-step explanation:

Let the restaurant sold x hotdogs and y hamburgers.

Given the restaurant sold 350 more hamburgers than hotdogs.

So, we can write x + 350 = y ....... (1)

Again given that the number of total hotdogs and hamburgers sold in the restaurant is 700.

So, x + y = 700 ........ (2)

Solving equations (1) and (2) we get  

2x + 350 =700

⇒ 2x = 350

⇒ x = 175

Then from equation (1) we get,

y = 350 + 175 = 525

Therefore, the restaurant sold 175 hotdogs and 525 hamburgers. (Answer)

The equation of the line containing the given pair of points (4.6 , -8) and (6.6 , 2.2) is y = 5.1 x - 31.46

Step-by-step explanation:

The equation of a line is y = m x + b, where

∵ The line contains the points (4.6 , -8) and (6.6 , 2.2)

∴ [tex]x_{1}[/tex] = 4.6 and [tex]x_{2}[/tex] = 6.6

∴ [tex]y_{1}[/tex] = -8 and [tex]y_{2}[/tex] = 2.2

∵ [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

- Substitute the values above in the rule of m

∴ [tex]m=\frac{2.2-(-8)}{6.6-4.6}=\frac{2.2+8}{2}=\frac{10.2}{2}=5.1[/tex]

∴ The slope of the line is 5.1

∵ The equation of a line is y = m x + b

Substitute m by 5.1

∴ y = 5.1 x + b

To find b substitute x and y by the coordinates of point (4.6 , -8) OR point (6.6 , 2.2)

∵ x = 6.6 and y = 2.2

∴ 2.2 = 5.1(6.6) + b

∴ 2.2 = 33.66 + b

- Subtract 33.66 from both sides

∴ -31.46 = b

∴ y = 5.1 x + (-31.46)

∴ y = 5.1 x - 31.46

The equation of the line containing the given pair of points (4.6 , -8) and (6.6 , 2.2) is y = 5.1 x - 31.46

To find the three consecutive odd integers, we can solve an equation representing the given information.

Let the smallest odd integer be x. The next consecutive odd integer will be x + 2, and the largest odd integer will be x + 4.

The problem states that when the larger two integers are added, the result is nine less than three times the smallest integer:

(x + 2) + (x + 4) = 3x - 9

Simplifying the equation, we have:

2x + 6 = 3x - 9

Adding 9 to both sides:

2x + 15 = 3x

Subtracting 2x from both sides:

15 = x

So the smallest odd integer is 15. The consecutive odd integers are 15, 17, and 19.

Final answer:

To find the intercepts of the given line, the equation is rearranged into the slope-intercept form, revealing the y-intercept directly and allowing for easy calculation of the x-intercept by setting y=0. Thus, the x-intercept is 4/3.

Explanation:

To determine the intercepts of the line given by the equation -3x - 4 = -5y - 8, we should find both the x-intercept and y-intercept. The general form of a line is given by y = mx + b, where m is the slope, and b is the y-intercept.

Steps to find the intercepts:

Rearrange the equation to the slope-intercept form y = mx + b by adding 3x to both sides and then adding 8, resulting in -5y = 3x - 4. By further dividing both sides by -5, we get  y = -3/5x + 4/5.

To find the y-intercept (b), set x=0 in the rearranged equation, which gives y = 4/5. Thus, the y-intercept is 4/5.

To find the x-intercept, set y=0 in the rearranged equation, resulting in 0 = -3/5x + 4/5. Multiplying both sides by 5 and then dividing by -3, we find x = 4/3. Thus, the x-intercept is 4/3.

Answer:

The number of dimes = 32

The number of quarters  = 14

Step-by-step explanation:

Here, the total number of coins combined = 46

Let us assume the number of dimes = m

So, the Number of quarter = Total Coins - Number of dimes  = 46 - m

Now,as we know:

1 dime = $0.1

So, m dimes  = m x ($0.1) = $(0.1 m)

1 Quarter  = $0.25

So, ( 46 - m ) Quarters  = (46 - m ) x ( $ 0.25)   = 11.5 - 0.25 m

Also, given the total amount of coins = $ 6.70

⇒ Value of (Dimes + Quarters) = $ 6.70

or, (0.1 m) +  11.5 - 0.25 m  = 6.70

-0.15 m = - 4.8

or, m = 4.8/0.15  =  32

⇒ m = 32

Hence, the number of dimes = m = 32

And the number of quarters  = 46 - m= 46 -32 = 14

Since the multiplicative inverse of a fraction p/q is the fraction that swaps its numerator and denominator, i.e. q/p, we have that the inverse of 2/3 is 3/2.

So, if we multiply both sides of the equation by 3/2, we have

[tex]\dfrac{3}{2}\cdot\dfrac{2}{3}a=16\cdot\dfrac{3}{2}[/tex]

3/2 and 2/3 are multiplicative inverse of each other, and by definition this means that they give 1 when multiplied:

[tex]\dfrac{3}{2}\cdot\dfrac{2}{3}a=1\cdot a=a=16\cdot\dfrac{3}{2}[/tex]

On the right hand side, we have

[tex]16\cdot\dfrac{3}{2}=8\cdot 3=24[/tex]

h(x) = 4x - 10

Step-by-step explanation:

The given is:

We need to find h(x) = f(x) + g(x)

∵ f(x) = -2

∵ g(x) = 4x - 8

∵ h(x) = f(x) + g(x)

- Substitute f(x) and g(x) in h(x), and then add the like terms

∴ h(x) = (-2) + (4x - 8)

- Simplify the right hand side

∴ h(x) = -2 + 4x - 8

- Add like terms in the right hand side

∴ h(x) = 4x + (-2 - 8)

∵ -2 - 8 = -10

∴ h(x) = 4x + (-10)

∴ h(x) = 4x - 10

h(x) = 4x - 10
