Step-by-step explanation:

Answer:

(g ￮ f)(-2) = 32

Step-by-step explanation:

Given

[tex]f(x)=5x+4[/tex]

[tex]g\left(x\right)=x^2-4[/tex]

We have to evaluate (g ￮ f)(-2), so first we will evaluate f(-2) then use this value to evaluate g(x).

Finding f(-2)

[tex]f(x)=5x+4[/tex]

[tex]f(-2) = 5(-2)+4[/tex]

          [tex]= -10 + 4[/tex]

          [tex]= -6[/tex]

Then

[tex]g\left(-6\right)=\left(-6\right)^2-4[/tex]

          [tex]=36-4[/tex]

          [tex]= 32[/tex]

Therefore,

(g ￮ f)(-2) = 32

The equation of the graph is [tex]x = \frac 1{24}y^2[/tex]

Generally, a point is represented as:

(x,y)

The line x = -6 means that:

(-6, y)

So, we calculate the distance between (x,y) and (-6, y) as follows:

[tex]d = \sqrt{(x + 6)^2 + (y - y)^2}[/tex]

This gives

[tex]d = \sqrt{(x + 6)^2 }[/tex]

Next, we calculate the distance between (6,0) and (x, y) as follows:

[tex]d = \sqrt{(x - 6)^2 + (y - 0)^2}[/tex]

This gives

[tex]d = \sqrt{(x - 6)^2 + y^2}[/tex]

Equate both distance expressions

[tex]\sqrt{(x + 6)^2} = \sqrt{(x - 6)^2 + y^2}[/tex]

Square both sides

[tex](x + 6)^2 = (x - 6)^2 + y^2[/tex]

Expand

[tex]x^2 + 12x + 36 = x^2 - 12x + 36 + y^2[/tex]

Evaluate the like terms

[tex]12x = - 12x + y^2[/tex]

Add 12x to both sides

[tex]y^2 = 24x[/tex]

Make x the subject.

[tex]x = \frac 1{24}y^2[/tex]

Hence, the equation of the graph is [tex]x = \frac 1{24}y^2[/tex]

Answer:

B. (U+V)(U-V)

Step-by-step explanation:

Factoring

The given expression is:

[tex]4x^2-9y^6[/tex]

It should be noted that both terms are perfect squares:

[tex](2x)^2=4x^2[/tex]

[tex](3y^3)^2=9y^6[/tex]

Since it's a difference of squares, we need to use the following pattern to factor the required expression:

[tex](U^2-V^2)=(U+V)(U-V)[/tex]

Thus, the answer is

B. (U+V)(U-V)

Step-by-step explanation:

Simplifying

2.1(0.2x + -1.4) = 1.3(0.4x + -3.5)

Reorder the terms:

2.1(-1.4 + 0.2x) = 1.3(0.4x + -3.5)

(-1.4 * 2.1 + 0.2x * 2.1) = 1.3(0.4x + -3.5)

(-2.94 + 0.42x) = 1.3(0.4x + -3.5)

Reorder the terms:

-2.94 + 0.42x = 1.3(-3.5 + 0.4x)

-2.94 + 0.42x = (-3.5 * 1.3 + 0.4x * 1.3)

-2.94 + 0.42x = (-4.55 + 0.52x)

Solving

-2.94 + 0.42x = -4.55 + 0.52x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-0.52x' to each side of the equation.

-2.94 + 0.42x + -0.52x = -4.55 + 0.52x + -0.52x

Combine like terms: 0.42x + -0.52x = -0.1x

-2.94 + -0.1x = -4.55 + 0.52x + -0.52x

Combine like terms: 0.52x + -0.52x = 0.00

-2.94 + -0.1x = -4.55 + 0.00

-2.94 + -0.1x = -4.55

Add '2.94' to each side of the equation.

-2.94 + 2.94 + -0.1x = -4.55 + 2.94

Combine like terms: -2.94 + 2.94 = 0.00

0.00 + -0.1x = -4.55 + 2.94

-0.1x = -4.55 + 2.94

Combine like terms: -4.55 + 2.94 = -1.61

-0.1x = -1.61

Divide each side by '-0.1'.

x = 16.1

x = 16.1

Answer:

The larger number is 40, and the smaller one is 23.

Step-by-step explanation:

Let x be the larger number.

Let x - 17 be the smaller number.

x + (x - 17) = 63

2x - 17 = 63

2x = 80

x = 40

Hence, the smaller number is 40 - 17 = 23.

Answer:

a.4845ways.

b. 14535ways.

c. 3990ways

d. 1140ways

Step-by-step explanation:

Given data:

No of flavors available to customers = 20.

Solution:

This is permutation and combinations problem,

(a) how many ways can the customers choose 4 different ice creams if they are all of different flavors.

20C4

= n!/(n-k)!)k!

= 20!/(20-4)!)4!

= 20!/(16)!)4!

= 4845ways.

b) are not necessarily of different flavors

Let’s say any two same flavors can be chosen.

20C4 * 3!/2!

= 4845 * 3

= 14535ways.

c) contain only 2 or 3 flavors.

= 20C3 * 3!/2!

= 1140 * 3

= 3420

20C2 * 3

= 190 * 3

= 570.

No of 2 or 3 different flavors

= 3420 + 570

= 3990ways.

d) contain 3 different flavors.

20C3

= n!/(n-k)!)k!

= 20!/(20-3)!)3!

= 1140ways.

Answer:

5 ft/yr

Step-by-step explanation:

This is the whole question: A tree initially measured 18 ft tall. Over the next 3 1/2 years, it grew to a final height of 35 1/2 feet. During those 3 1 /2 years, what was the average yearly growth rate of the height of the tree?

The tree grew   35.5 - 18 ft = 17.5 feet in 3.5 years      

This average leads to   17.5 ft / 3.5 yr =  5 ft/yr

The question is incomplete, the complete question is;

A tree measured 18 feet tall. Over the next 3 1/2 years, it grew to final height of 35 1/2 feet. During those 3 1/2 years, what was the average yearly  growth rate of the height of the tree?

Answer:

5 feet per year

Step-by-step explanation:

Given that the initial height of the tree = 18 feet

Final height of the tree = 35.5 feet

Time interval = 3.5 years

Now;

Increase in length of tree = Final height of the tree - initial height of the tree

Increase in length of tree =  35.5 - 18 = 17.5 feet

Rate of growth of tree = increase in height of tree/ time taken

Rate of growth of tree = 17.5 feet/ 3.5 years

Rate of growth of tree = 5 feet per year

Answer:

Each space should be 6.83333 feet wide.

Step-by-step explanation:

a) Data and Calculations:

Lot = 41 feet wide

Dividers = 6 feet wide

For even spacing, 41/6 = 6.83333 feet

b) The quotient is equal to the dividend divided by the divisor.  Since the lot is 41 feet wide, the quotient, when divided by some 6-feet wide dividers, will be equal to 6.83333 or 7 feet wide.  This implies that each divider will occupy a space equivalent to 7 feet or specifically 6.83333 feet wide.

Answer:

315

Step-by-step explanation:

The sum of -265 and -156:

-265 + (-156)

= -265-156

= -421

The sum of 356 and -250:

356 + (-250)

= 356-250

= 106

The sum of both:

Answer:

25%

Step-by-step explanation:

This is like a part over whole problem, where 24 blue pens is the part and 96 pens total is the whole.

24/96 = 0.25 * 100 = 25%

Answer:

Of the 96 pins, 25% of the pins were blue.

Step-by-step explanation:

We are given that Martina ordered 96 pins in total. We are also given that she ordered 24 blue pins.

With this, we can determine how many of the pins were not blue pins by subtracting the amount of blue pins from the number of total pins.

[tex]96 \ \text{total pins} - 24 \ \text{blue pins} = 72 \ \text{orange pins}[/tex]

Now, we can divide the number of blue pins by the number of total pins to determine the fraction of blue pins to total pins.

[tex]\displaystyle \frac{24}{96} = \frac{12}{48} = \frac{6}{24} = \frac{3}{12} = \frac{1}{4}[/tex]

Then, we can convert our fraction to a decimal.

[tex]\displaystyle \frac{1}{4} = 0.25[/tex]

And finally, we can convert our decimal to a percentage by multiplying the determined decimal by 100.

[tex]0.25\times100 = 25\%[/tex]

Therefore, of the 96 pins that Martina ordered, 25% of them were blue.
