f (x)=4x-7 when f (x)=8

Answers

Answer 1
Since both are equivalent to f(x), 4x-7 must equal 8
4x-7=8

Add 7 to both sides
4x= 15

Divide both sides by 4
x=15/4

Final answer: x=15/4

[tex]\bf \left( \cfrac{750}{512} \right)^{\frac{1}{3}}\implies \cfrac{750^{\frac{1}{3}}}{512^{\frac{1}{3}}}\implies \cfrac{\sqrt[3]{750^1}}{\sqrt[3]{512^1}}\quad \begin{cases} 750=2\cdot 3\cdot 5\cdot 5\cdot 5\\ \qquad 2\cdot 3\cdot 5^3\\ \qquad 6\cdot 5^3\\ 512=8\cdot 8\cdot 8\\ \qquad 8^3 \end{cases} \\\\\\ \cfrac{\sqrt[3]{750}}{\sqrt[3]{512}}\implies \cfrac{\sqrt[3]{6\cdot 5^3}}{\sqrt[3]{8^3}}\implies \cfrac{5\sqrt[3]{6}}{8}[/tex]

Answer:

[tex]\frac{5\sqrt[3]{6}}{8}[/tex]

Step-by-step explanation:

We have been given an exponential number. We are supposed to simplify our given number.

[tex](\frac{750}{512})^{\frac{1}{3}[/tex]  

Using fractional exponent rule [tex]x^\frac{m}{n}=\sqrt[n]{x^m}[/tex], w ecan write our given number as:

[tex](\frac{750}{512})^{\frac{1}{3}}=\sqrt[3]{(\frac{750}{512})^1}[/tex]

[tex](\frac{750}{512})^{\frac{1}{3}}=\sqrt[3]{\frac{750}{512}}[/tex]

We can rewrite 512 as [tex]8^3[/tex] and 750 as 125*6.

[tex](\frac{750}{512})^{\frac{1}{3}}=\sqrt[3]{\frac{125*6}{8^3}}[/tex]

We can rewrite 125 as [tex]5^3[/tex]

[tex](\frac{750}{512})^{\frac{1}{3}}=\sqrt[3]{\frac{5^3*6}{8^3}}[/tex]

Using radical rule [tex]\sqrt[n]{a^n}=a[/tex], we will get:

[tex](\frac{750}{512})^{\frac{1}{3}}=\frac{5\sqrt[3]{6}}{8}[/tex]

Therefore, [tex]\frac{5\sqrt[3]{6}}{8}[/tex] is equivalent to our given number.

I have a math question

Answers

For the first question; we have a problem dealing with translations. Our goal is to translate the word problem into an algebraic one. So our numbers are 60, 2, and 5. Our variable, or the letter holding the unknown number's place value,  is N. 

The problem states that 60 is MORE THAN the PRODUCT of 5 and N. Focus on the words I bolded and capitalized. These are your key words that tells you what operations you need to use. Note that 'product' signals the operation of multiplication (Since the answer you get from multiplying numbers is called the 'product'.) and 'more than' signals the operation of addition (Because you are left off with more than you originally had before adding). 

Now that we know that our algebraic expression contains multiplication, addition, letter N and the numbers 2 and 5; we can start plugging the numbers in.

60 = 2 (more than) + (product of) 5N. The answer for the first attachment is B. 

_____________________________________________________________

All we need to do for the AB problem (Question 25 on your material) is solve AB.

Note 1: When a problem has no operation separating two letters or numbers, this means multiplication.

Note 2: A and B are variables. Variables are letters that stand for and hold the place of our unknown quantities. However, the values are not unknown anymore given the fact that the question tells us that A= 42 and B = 2. Thus we substitute A with 42 and B with 2, then work from there. 42 * 2 =84. Answer = A.

____________________________________________________________________

And finally, for question 26, we use PEMDAS. P = parenthesis (), E = exponent x^2, M/D = x or /, A/S means + or subtraction.

According to PEMDAS, we first solve what's parenthesis, which is 77 – 32. Using mental math, 77 – 32 = 45. ( 7 – 3 = 4 and 7 – 2 = 5.). 5/9 * 45 is what we have left. 5 divided by 9 =0.5555555555555556. 0.5555555555555556 * 45 = 25. Answer is D.

Write an algebraic expression that is equivalent to the expression cot(arctan x)

Answers

cosX/sinX [tan-¹X]
cos²x/sin²x = cot²x
recall cot²x = cosec²x - 1

The algebraic expression equivalent to cot(arctan x) is 1 / x, derived by recognizing that cot(θ) is the reciprocal of tan(θ), and tan(θ) = x for θ = tan-1(x)

To find an algebraic expression for cot(arctan x), let's follow a step-by-step transformation using trigonometric identities: cot(arctan x) is denoted as cot(tan-1(x))

First, let
θ = tan-1(x). By definition of the arctan function, we have the relation:tan(θ) = x.Next, we need to find cot(θ). Recall that:cot(θ) = 1 / tan(θ).Since tan(θ) = x, we substitute to get:cot(θ) = 1 / x .Thus, we have cot(tan-1(x)) = 1 / x.

Therefore, the algebraic expression equivalent to cot(tan-1(x)) is 1 / x.

the volume of the sphere is increased by 72.8%. what is the percentage increase in the radius?

Answers

Final answer:

The volume of a sphere increases by 72.8%, which after calculations, results in a 20% increase in the radius of the sphere.

Explanation:

The volume of a sphere is given by the formula V = (4/3)πr³, where r is the radius of the sphere. An increase in volume by 72.8% implies that the new volume V' is equal to 1.728 times the original volume V. To find the percentage increase in the radius, we use the relationship between volume and radius:

V' = (4/3)πr'^3, where r' is the new radius after increase. Since V' = 1.728V, we have:

1.728 (4/3)πr³ = (4/3)π[tex]r'^3[/tex]Therefore, [tex]r'^3[/tex] = 1.728r³.

After taking the cube root of both sides, we obtain:

r' = ∛1.728 * r ≈ 1.200 * r

Thus, the new radius is approximately 120% of the original radius, which means there is a 20% increase in the radius.

Final answer:

To calculate the percentage increase in the radius of the sphere when the volume is increased by 72.8%, we can use the formula for volume and solve for the new radius in terms of the original radius. The percentage increase in radius is then calculated by comparing the new and original radius.

Explanation:

The volume of a sphere is given by the formula V = (4/3)πr³, where r is the radius of the sphere. If the volume of the sphere is increased by 72.8%, we can calculate the new volume by multiplying the original volume by 1 + 0.728. Let's denote the original radius as r1 and the new radius as r2.

The formula for volume can be written as V = (4/3)πr³. Substituting r1 and r2 into the formula, we get:

Original volume: V1 = (4/3)πr1³New volume: V2 = (4/3)πr2³

Since the two volumes are related by the percentage increase (1 + 0.728), we can write the equation:

(1 + 0.728)V1 = V2

Now, let's solve for r2 in terms of r1:

(1 + 0.728)V1 = (4/3)πr2³

r2 = ([(1 + 0.728)V1] * (3/4π))^(1/3)

Finally, we can calculate the percentage increase in the radius by comparing r2 to r1:

Percentage increase in radius = (r2 - r1) / r1 × 100%

Problem 7

This is a 30-60-90 triangle. The short leg is half of the hypotenuse so 12/2 = 6 units long

The long leg, x, is equal to sqrt(3) times the short leg

long leg = (short leg)*sqrt(3)
long leg = (6)*sqrt(3)
long leg = 6*sqrt(3)

Answer: Choice B

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

Problem 8

This is a 45-45-90 triangle. The two legs are congruent. In this case, they are both 7*sqrt(2) units long. 

Hypotenuse = (leg)*sqrt(2)
Hypotenuse = (7*sqrt(2))*sqrt(2)
Hypotenuse = 7*(sqrt(2)*sqrt(2))
Hypotenuse = 7*sqrt(2*2)
Hypotenuse = 7*sqrt(4)
Hypotenuse = 7*2
Hypotenuse = 14

So the value of x is 14

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

Problem 9

Use the SAS area of a triangle rule

Area of triangle = 0.5*(side1)*(side2)*sin(included angle)
A = 0.5*(8)*(12)*sin(65)
A = 48*sin(65)
A = 43.5027737777591
A = 43.5

Answer: 43.5

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

Problem 10

Angle C is the included angle (aka the angle between the given sides). Like with problem 9, we use the SAS area rule

Area = 0.5*(side1)*(side2)*sin(included angle)
Area = 0.5*12*1.5*sin(63)
Area = 9*sin(63)
Area = 8.01905871769531
Area = 8.02

Answer: 8.02

Given Info:
DM = 17 yards
GM = 15 yards
angle M = 81 degrees

What we want to find: 
distance from D to G, aka the length of DG
Call this value x for now

Use the law of cosines to find x
(DG)^2 = (DM)^2 + (GM)^2 - 2*(DM)*(GM)*cos(M)
x^2 = 17^2 + 15^2 - 2*17*15*cos(81)
x^2 = 289 + 225 - 510*cos(81)
x^2 = 514 - 510*cos(81)
x^2 = 514 - 79.7815771705178
x^2 = 434.218422829482
sqrt(x^2) = sqrt(434.218422829482)
x = 20.8379083122439

Rounded to the nearest yard, the distance from Garret to Dino is roughly 21 yards.

What is Trigonometry?

Trigonometry is a discipline of mathematics that studies the relationship between the sides of a triangle (right triangle) and their angles. There are six trigonometric functions that define the relationship between sides and angles.

1. Using Trigonometry

sin 60 = P/H

√3/2 = x/ 12

x = 12√3 / 2

x= 6√3

2. Using Trigonometry

sin 60 = P/H

1/√2 = 7√2 / x

x/√2 = 7√2

x = 14 unit

3. Using sine law

sin 75 /11 = sin 54 / x

0.965 / 11 = 0.809 / x

0.0877 = 0.809 / x

x = 9.224 miles

which number is a solution of the inequality 12 < y(8-y)

Answers

The solution to the inequality 12 < y(8 - y) is y such that 2 < y < 6.

The solution of the inequality 12 < y(8 - y), you can start by simplifying the expression on the right side: y(8 - y)
Distribute the y on the right side: 8y - [tex]y^2[/tex]
Now, substitute this expression back into the original inequality: [tex]12 < 8y - y^2[/tex]
Rearrange the terms to form a quadratic inequality: [tex]y^2 - 8y + 12 > 0[/tex]

Now, factor the quadratic expression: (y - 2)(y - 6) > 0
To solve for y, set each factor equal to zero and find the critical points: y - 2 = 0 or y - 6 = 0
Solving these equations gives y = 2 and y = 6.

Now, create intervals using these critical points and test a value in each interval:
1. Test y = 1: (1 - 2)(1 - 6) = (-1)(-5) = 5 > 0
2. Test y = 3: (3 - 2)(3 - 6) = (1)(-3) = -3 < 0
3. Test y = 7: (7 - 2)(7 - 6) = (5)(1) = 5 > 0
The solution is y such that 2 < y < 6

Find the average rate of change for f(x) = x2 + 9x + 18 from x = −8 to x = −2.
A)−1
B)−3
C)1
D)3

Answers

In order to find the average rate of change, we must take the values at x=-8 and x= -2, and determine what the slope would be if a line was drawn between the two points. 
f(-8) = -8² +9(-8) + 18
f(-8) = 10

f(-2) = -2² + 9(-2) + 18
f(-2) =4 -18 +18
f(-2) = 4

f(-8) =10 and f(-2)=4

if a line was drawn between the two points (-8,10) and (-2,4) the slope (rise/run) would be -6/6, since the line would go down 6 units from 10 to 4, and over 6 units from x=-8 to x=-2.

The average rate of change, therefore, is -6/6, or
