I just got it right

The speed in running is 10 mph and speed in biking is 16 mph

Solution:

Given that, Cruz is training to compete in a triathlon

He left his house at 6:00 and ran until 7:30

Time taken for running = 1.5 hours

Then he rode his bike until 9:45

7: 30 to 9: 45 is biking time

Time taken for biking = 2.25 hours

He covered a total distance of 51 miles

Total distance = 51 miles

Let "x" be the speed in running

His speed when biking was 1.6 times his speed when running

Speed in biking = 1.6x

Total distance = distance in running + distance in biking

The distance is given by formula:

[tex]distance = speed \times time[/tex]

Therefore,

[tex]Total\ Distance = x \times 1.5 + 1.6x \times 2.25\\\\51 = 1.5x + 3.6x\\\\5.1x = 51\\\\x = 10[/tex]

Thus speed in running is 10 miles per hour

Speed in biking = 1.6x = 1.6(10) = 16

Thus speed in running is 10 mph and speed in biking is 16 mph

[tex](f+g)(x) \text{ is equal to } x^2+x-8[/tex]

Solution:

Given that the functions are:

[tex]f(x) = x-8\\\\g(x)=x^2[/tex]

We have to find the value of (f + g)(x)

By operations on functions, we know that,

(f + g)(x) = f (x) + g(x)

Thus (f + g)(x) can be found by adding both the given functions

[tex](f + g)(x) = f (x) + g(x)\\\\(f + g)(x) = x - 8 + x^2\\\\(f + g)(x) = x^2+x-8[/tex]

Thus (f + g)(x) is equal to [tex]x^2+x-8[/tex]

Answer:

The number of games Sydney played is 5 and the number of rides she went on is 8.

Step-by-step explanation:

Given:

Sydney is going to a carnival that has games and rides. Each game costs $1.25 and  each ride costs $2.25. Sydney spent $24.25 altogether at the carnival and the number  of rides she went on is 3 more than the number of games she played.

Now, to find the number of games Sydney played and the number of rides she went on.

Let the number of games she played be [tex]x.[/tex]

As given, the number  of rides she went on is 3 more than the number of games she played.

So, the number of rides be [tex]x+3.[/tex]

Each game costs $1.25 and  each ride costs $2.25. Sydney spent $24.25 altogether at the carnival.

According to question:

[tex]1.25x+2.25(x+3)=24.25[/tex]

[tex]1.25x+2.25x+6.75=24.25[/tex]

[tex]3.50x+6.75=24.25[/tex]

Subtracting both sides by 6.75 we get:

[tex]3.50x=17.50[/tex]

Dividing both sides by 3.50 we get:

[tex]x=5.[/tex]

Number of games = 5.

So, number of rides:

[tex]x+3\\=5+3\\=8.[/tex]

Therefore, the number of games Sydney played is 5 and the number of rides she went on is 8.

Answer:

2102

Step-by-step explanation:

Evaluate   -x³+3x²+5x+1   when x = -12

simply substitue x = -12 into the equation

-x³+3x²+5x+1   when x = -12

= - (-12)³ + 3(-12)² + 5(-12)+1

= -(-1728) + 3(144) - 60 + 1

= 1728 + 432 - 60 +1

= 2102

To evaluate the polynomial -x^3 + 3x^2 + 5x + 1 for x = -12, we substitute -12 for x and simplify, resulting in a final value of 2101.

The student is asking to evaluate the polynomial -x^3 + 3x^2 + 5x + 1 when x = -12. To solve this, we substitute -12 for x in the polynomial and simplify:

Therefore, when x = -12, the polynomial evaluates to 2101.

800 dentists recommended Flash toothpaste

Solution:

Given that, magazine as states that 4 out of 7 dentists prefer flash toothpaste

1400 dentists were surveyed

To find: Number of dentists recommended falsh toothpaste

Let "x" be the number of dentists recommended falsh toothpaste

Then, we can say,

4 out of 7 equals x out of 1400

[tex]\rightarrow \frac{4}{7} = x \times 1400\\\\\rightarrow x = \frac{4}{7} \times 1400\\\\\rightarrow x = 800[/tex]

Thus 800 dentists recommended Flash toothpaste

The length of side CD is 11.

To find the length of side CD, we can use the distance formula, which is as follows:

distance = √((x2 - x1)^2 + (y2 - y1)^2)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

In this case, the coordinates of the two points are (-4, -5) and (-4, 6). Substituting these coordinates into the distance formula, we get:

distance = √(((-4) - (-4))^2 + ((6) - (-5))^2)

distance = √(0^2 + 11^2)

distance = √121

distance = 11

Therefore, the length of side CD is 11.

Answer:

The range is the resulting y-values we get after substituting all the possible x-values.

For the given function : [tex]f(x) = \frac{3}{4x} -4[/tex]

See the attached figure.

The zeros of the denominator at x = 0

The domain is: (-∞,0)∪(0,∞)

The range of the function is the domain of the inverse function of f(x)

y = 3/(4x) - 4

y + 4 = 3/(4x)

4x = 3/(y+4)

[tex]x=\frac{3}{4(y+4)}[/tex]

The zeros of the inverse function:

4(y+4) = 0

y + 4 = 0

y = -4

∴ The range is (-∞,-4)∪(-4,∞)

So, the answer is {y | y > –4} ∪ {y | y < – 4}

=========================================

Note: If the given function is : [tex]f(x) = \frac{3}{4} x-4[/tex]

It will be first degree polynomial function.

Both of the domain and the range = all real numbers R

Answer:

C

Step-by-step explanation:

Answer:

C.

Step-by-step explanation:

Consider the numerator;

When (x - 3)(x - 4) = 0

x = 3 or x = 4.

When x > 3 and < 4 (x - 3)(x- 4)  will be negative and the denominator  (x - 5(x + 6)^2 will be negative so the function will be positive.

So 3  < x < 4 is a part of the answer.

When x > 5 the denominator will be positive  and so will be the numerator.

So x > 5 also is a solution.

When x < 3 the numerator will be positive and the denominator will be negative so the function will be negative.

Answer:

The minimum value for  [tex]f(x) = 0.15(x + 1)^2 - 3[/tex] is [tex]-3[/tex].

Step-by-step explanation:

Given function is [tex]f(x) = 0.15(x + 1)^2 - 3[/tex]

We need to find the maximum value or the minimum value for the function.

Now, differentiate [tex]f(x) = 0.15(x + 1)^2 - 3[/tex]  w.r.t [tex]x[/tex].

[tex]f'(x) =\frac{d}{dx}(0.15(x + 1)^2 - 3)\\f'(x)=\frac{d}{dx}(0.15(x+1)^2-\frac{d}{dx}(3)\\[/tex]

[tex]f'(x)=2\times 0.15(x+1)\frac{d}{dx}(x+1)-0\\f'(x)=0.3(x+1)(1)\\f'(x)=0.3(x+1)[/tex]

Now, we will equate [tex]f'(x)=0[/tex] to find critical point.

[tex]0.3(x+1)=0\\x=-1[/tex]

Plug this critical point in to the function [tex]f(x) = 0.15(x + 1)^2 - 3[/tex]  we get,

[tex]f(-1) = 0.15(-1 + 1)^2 - 3\\f(-1)=-3[/tex]

Also, [tex]f''(x)=0.3[/tex] which is positive, We have minimum value.

So, the minimum value for  [tex]f(x) = 0.15(x + 1)^2 - 3[/tex] is [tex]-3[/tex].

Answer:

Step-by-step explanation:

m is the slope

y=mx+b

y is equation

m is slope (movement)

b is base

In the equation y=-2x+7, the rate of change (slope) is -2, denoting that for every unit increase in x, y decreases by 2. The +7 represents the y-intercept, the value of y when x equals zero. This concept is fundamental in understanding linear equations, where the rate of change is constant.

In the equation y=-2x+7, the rate of change is represented by the coefficient of the x variable, which in this case is -2. This signifies that for each unit increase in x, the value of y decreases by 2. In the context of graphing, this slope (or rate of change) would mean for every step to the right (increase in x), you would take two steps down (decrease in y). For example, if x were to increase from 1 to 2, y would decrease from 5 (plugging x=1 into the equation gives y=5) to 3 (plugging x=2 into the equation gives y=3).

The rate of change is a crucial concept in algebra and lies at the heart of most mathematical models. It plays a vital role in calculus, physics, and engineering, amongst other disciplines. The second number in the equation, '+7', signifies the y-intercept, which is the value of y when x equals zero. This equation represents a straight line, as all linear equations do, and the rate of change (or the slope) is constant across this line.
