Answer:

t = 4

Step-by-step explanation:

To solve for t, convert the numbers to improper functions. Then multiply by 16/3 on each side.

t ÷ 5 1/3 = 3/4

t ÷ 16/3 = 3/4

t = 16/3 * 3/4

t = 48/12

t = 4

Answer:

x = 5

Step-by-step explanation:

As you know 32 = 2^5

so

2^x = 32

2^x = 2^5

Since both have same base 2

x = 5

32=2^x

Prime factors of 32

32 = 2 * 16

16 = 2 * 8

8 = 2 * 4

4 = 2 * 2

32 = 2*2*2*2*2

32 = 2^5

x=5

Answer:

option (a)

x - √7x / x - 7

Step-by-step explanation:

Given the expression in the question

  √x / (√x + √7)

 There are 3 steps to follow

Multiply by √x - √7

√x (√x - √7) /  (√x + √7)(√x - √7)

√x .√x - √7.√x / (√x + √7)(√x - √7)

a² - b² = (a+b)(a-b)

√x² - √7x / √x² - √7²

x - √7x / x - 7

Answer:

OPTION B:  [tex]2(3x+5)[/tex]

Step-by-step explanation:

To solve the exercise you can simplify the expression given in the problem, as following:

- Add the like terms:

[tex]3x+3x+5+5\\6x+10[/tex]

- Find the greatest common factor (GCF) of 6 and 10:

[tex]6=2*3\\10=2*5\\\\GCF=2[/tex]

- Factor ir out.

Then, you obtain the following equivalent expression:

[tex]2(3x+5)[/tex]

Answer:

6x + 10

Step-by-step explanation:

Combine like terms:

3x + 3x = 6x, and

5+5 = 10

and so the final sum is 6x + 10

it is a function because each input (x) has a unique output (y) that is not repeated

In order for a relationship between numbers x and y to be considered a function from x to y, you need to have one unique y for every x. This doesn’t mean that each y needs exactly one x; for instance, the function y = x² is a function from x to y and has two y values associated with most x values (x = 2 and x = -2, for instance, both give you y = 4).

Essentially, if we give a function some x value, we want to know exactly what y value we’re getting out of it.

The pictured table gives you two possible values for x = 2; given a 2 as input, we have no idea whether to go to 1 or 7 for our output, so it would not be a function from x to y.

(Interestingly, a function from y to x would satisfy that “one output per input” requirement, so if you wanted to impress your teacher, you could answer “yes, but only from y to x, NOT x to y”)

Answer:

Step-by-step explanation:

What you are trying to do is a nice way to solve this problem. Without knowing any physics, you are using what math you know to get the answer. You are actually very close to being correct, and you are right. You do have to divide by 60.

Here's why and it is the one bit of physics you have to know.

The speed is km/hour. That word hour is the culprit. Your time is in minutes and you have to get it into hours. In physics, the units have to be consistent.

So ...

b1 = 19 minutes which is 19 min [1 hour / 60 minutes] = 19/60 = 0.31667 hour

b2 = 26 minutes which is 26 min [ 1 hour/60 minutes] =  26/60 = 0.4333 hour

h = 40 km/hour

Area = (0.31667 hour + 0.4333 hour)*40 km/hour /2

Area = 0.75 hour * 40 km/hr //2

Area = 15 km

Answer:

(- 3, - 5)

Step-by-step explanation:

A translation of 1 unit left, subtract 1 from x- coordinate

A translation of 3 units down, subtract 3 from y- coordinate

The translation rule is

(x, y) → (x - 1, y - 3), hence

(-2, - 2) → (- 2 - 1, - 2 - 3) → (- 3, - 5)

Answer:

Part a) The weight of the original statue is [tex]9,483\ pounds[/tex]

The ratio of the height of the original statue to the height of the small statue is 8.4

The ratio of the weights or volumes is [tex]8.4^{3}[/tex]

Part b)  [tex]221,184\ pounds[/tex]

Step-by-step explanation:

Part a)

we know that

If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor and the ratio of its volumes or weights is equal to the scale factor elevated to the cube

step 1

Find the scale factor

remember that

[tex]1\ ft=12\ in[/tex]

The original statue is 7 ft tall

Convert to inches

[tex]7\ ft=7*12=84\ in[/tex]

Divide the height of the original statue by the height of the model to find the scale factor

[tex]\frac{84}{10}=8.4[/tex]

step 2

Find the ratio of its weights

Let

z-----> the scale factor

x-----> the weight of the original statue

y----> the weight of the model

so

[tex]z^{3}=\frac{x}{y}[/tex]

we have

[tex]z=8.4[/tex]

[tex]y=16\ lb[/tex]

substitute

[tex]8.4^{3}=\frac{x}{16}[/tex]

[tex]x=16(8.4^{3})=9,483\ pounds[/tex]

The weight of the original statue is [tex]9,483\ pounds[/tex]

The ratio of the height of the original statue to the height of the small statue is 8.4

The ratio of the weights or volumes is [tex]8.4^{3}[/tex]

Part b) If the original statue were 20 ft tall, how much would it weight?

step 1

Find the scale factor

remember that

[tex]1\ ft=12\ in[/tex]

The original statue is 20 ft tall

Convert to inches

[tex]20\ ft=20*12=240\ in[/tex]

Divide the height of the original statue by the height of the model to find the scale factor

[tex]\frac{240}{10}=24[/tex]

step 2

Find the ratio of its weights

Let

z-----> the scale factor

x-----> the weight of the original statue

y----> the weight of the model

so

[tex]z^{3}=\frac{x}{y}[/tex]

we have

[tex]z=24[/tex]

[tex]y=16\ lb[/tex]

substitute

[tex]24^{3}=\frac{x}{16}[/tex]

[tex]x=16(24^{3})=221,184\ pounds[/tex]

Step-by-step explanation:

to find the axis of symmetry, the formula is X= -b/ 2a

a is the 2 from 2x2

and b is 4 from 4x

then plug them to the formula

-b= -4 because of the negative in -b

and 2a is 2(2)

-4/4 is -1

so x= -1

Answer:

The absolute number of a number a is written as

|a|

And represents the distance between a and 0 on a number line.

An absolute value equation is an equation that contains an absolute value expression. The equation

|x|=a

Has two solutions x = a and x = -a because both numbers are at the distance a from 0.

To solve an absolute value equation as

|x+7|=14

You begin by making it into two separate equations and then solving them separately.

x+7=14

x+7−7=14−7

x=7

or

x+7=−14

x+7−7=−14−7

x=−21

An absolute value equation has no solution if the absolute value expression equals a negative number since an absolute value can never be negative.

The inequality

|x|<2

Represents the distance between x and 0 that is less than 2

picture42

Whereas the inequality

|x|>2

Represents the distance between x and 0 that is greater than 2

picture43

You can write an absolute value inequality as a compound inequality.

$$\left | x \right |<2\: or

−2<x<2

This holds true for all absolute value inequalities.

|ax+b|<c,wherec>0

=−c<ax+b<c

|ax+b|>c,wherec>0

=ax+b<−corax+b>c

You can replace > above with ≥ and < with ≤.

When solving an absolute value inequality it's necessary to first isolate the absolute value expression on one side of the inequality before solving the inequality.

Constraints can be represented by absolute value equations when dealing with inequalities that involve the distance between a variable and a fixed value. Absolute value equations are commonly used to express constraints in mathematical modeling and optimization problems.

Constraints can be represented by absolute value equations when dealing with inequalities that involve the distance between a variable and a fixed value. Absolute value equations are commonly used to express constraints in mathematical modeling and optimization problems. Here's how you can do it:

Representing Constraints with "less than" or "greater than" inequalities:

Suppose you have a variable "x" and a fixed value "a." If you want to impose a constraint that the absolute value of the difference between "x" and "a" is less than some constant "k," you can write it as:

| x - a | < k

For example, if you want to constrain "x" to be within 3 units from 5, you write:

| x - 5 | < 3

Representing Constraints with "less than or equal to" or "greater than or equal to" inequalities:

If you want to impose a constraint that the absolute value of the difference between "x" and "a" is less than or equal to some constant "k," you can write it as:

| x - a | ≤ k

For example, if you want to constrain "x" to be within 2 units from 8, you write:

| x - 8 | ≤ 2

Using absolute value equations allows you to handle situations where the variable needs to be close to a certain value or within a specific range, regardless of whether it is greater or smaller than that value. This flexibility is particularly useful in various mathematical and optimization problems, including linear programming and constrained optimization.

#SPJ2

Answer:

angle = 35 degrees

Step-by-step explanation:

The rocket traveled

5 miles in the       x direction

3.5 miles in the    y direction

The rocket was launched with a slope of

m =y/x = 3.5 miles / 5 miles   = 0.7

The slope is equal to the tangent of the angle of elevation

tan (angle) = m

angle  =  tan^-1 (0.7)

angle = 34.99 ≈ 35 degrees

To determine the angle of elevation, we use the tangent function: the angle θ is the arctan of the altitude over the horizontal distance, which is approximately 35 degrees.

The angle of elevation that the rocket was launched at can be determined using trigonometric functions. Specifically, we can use the tangent function, which relates the angle of a right triangle to the ratio of the opposite side (altitude in this case) over the adjacent side (horizontal distance).

The formula is:

tan(\(\theta\)) = \(\frac{{opposite}}{{adjacent}}\).

So, the angle \(\theta\) is:

\(\theta = tan^{-1}\left(\frac{{3.5 \text{{ miles}}}}{{5 \text{{ miles}}}}\right)\).

Using a calculator, we find that:

\(\theta\approx 35.0^\circ).

The rocket was thus launched at an angle of approximately 35 degrees.

An equation f(4)=16 means that when the input value is 4, the output value is 16.

An equation in the form f(4)=16 means that when the input value of the function f is 4, the output value is 16.

For example, if f represents the function that multiplies an input by 4, then f(4)=16 because 4 multiplied by 4 equals 16.

In terms of input and output values, f(4)=16 means that when the input value is 4, the function will return an output value of 16.

Answer:

Answer:

The one that stands out as incorrect is B

Step-by-Step Explanation:

I'll assume that by 12, you meant 1/2 because if the scale factor is 12, then none of the choices are correct. B is the only one that stands out because while in the x, 10 does turn into 5 after being multiplied by 1/2, the 2 in the y remained the same instead of being turned into 1.

Answer:

This figure is dilated by a factor of 12, with the origin as center.  

Which statement is NOT correct?

A)R(2, 8) → R'(1, 4)

B)Q(10, 2) → Q'(5, 2)

C)P(2, -4) → P'(1, -2)

 D)S(-10, 2) → S'(-5, 1)

​

Step-by-step explanation:

As you can see in A,C and D, the x-coordinate and the y-coordinate is divided by 2.

E.g.  2 / 2 =1     8/2=4    so ⇒R'(1, 4)  

but in B, the first x-coordinate is divided by 2 but the y-coordinate is divided by 1.

Answer:

y-intercept at (0,5) and asymptote at y = 4.

Step-by-step explanation:

This graph has a base 3/4 that is less than 1. This means it will start high and end low.

It has also been shifted up 4 units by adding 4. This means the asymptote moves to from y = 0 to y =4. The y-intercept of the parent function will also move from (0,1) to (0,5).

Step By Step Explanation:

Statistical: A survey, branch or mathematics consisting of data collection, organization, analysis, interpretation and presentation.

A statistical question deals with social problems, people, or something that must be studied and data gained. Statistical questions must have data sets and data gained. They also must have answers that vary from side to side or opinion to opinion, in order to be qualified as a 'statistical question'.

Answer:

Step-by-step explanation:

We know:

If a ≤ b ≤ c are the sides of a triangle, then a + b > c.

We have a = x, b = 2x and c = 15 cm.

Therefore x ≤ 15 and 2x ≤ 15 ⇒ x ≤ 7.5

Therefore we have the inequality:

x + 2x > 15

3x > 15          divide both sides by 3

x > 5 and x ≤ 7.5

Finally x = 6

Answer: 7 + i

Step by step:

Remove parentheses.

5 + 3i + 2 - 2i

Add 5 and 2

7 + 3i - 2i

Subtract 2i and 3i

7 + i

The sum of the complex numbers (5+3i) and (2-2i) is 7+i. You add the real parts to get 7 and the imaginary parts to get i, then combine them.

Adding two complex numbers: (5+3i)+(2-2i). To perform this addition, we simply add the real parts and the imaginary parts separately. The real parts are 5 and 2, and when we add them together we get 7. The imaginary parts are 3i and -2i, which sum up to 1i (or just i). Hence, the result of the addition of these two complex numbers is 7+i.

To further clarify with an example similar to the student's question: (3+4i) + (−2+7i) = (3 - 2) + (4 + 7)i = 1 + 11i. The process is straightforward—add the real numbers, add the imaginary numbers, and combine them into one complex number.
