Solve the exponential function

f(0) equals 0. When x is 0 in the given function, the result of f(x) is also 0.

To find the value of f(x) when x=0 for the function f(x) = -1x, substitute 0 for x:

f(0) = -1(0) = 0.

Therefore, f(0) equals 0. When x is 0 in the given function, the result of f(x) is also 0.

Answer:

"The values for y are square roots of negative numbers"

Step-by-step explanation:

The steps shown are correct. But at the end we can see that we have to "take the negative square roots".

This means we have to take the square root of -1. In the real number system, we CANNOT take the square root of any negative number. Hence, there is NO SOLUTION to the system.

2nd answer choice, "The values for y are square roots of negative numbers", is right.

Answer:

x = 15; m<(3x) = 45; m<(2x + 15) = 45

Step-by-step explanation:

The measures of the angles measuring 3x and 2x + 15 add up to 90 degrees.

3x + 2x + 15 = 90

5x + 15 = 90

5x = 75

x = 15

m<(3x) = 3 * 15 = 45

m<(2x + 15) = 2 * 15 + 15 = 30 + 15 = 45

This question clearly states that it is a 'find the volume' question.

Given dimensions of the object are :

Length of the object = [tex]40\frac{1}{2}[/tex] inches or 40.5 inches

Depth of the object = 10 inches

Height of the object is = 8 inches

So, the volume becomes = [tex]40.5\times10\times8[/tex] = 3240 cubic inch

Hence, the amount of cement needed is 3240 cubic inches.

To fill the form, you use the formula for the volume of a rectangular prism (length x width x height) to find that 3240 cubic inches of cement is needed.

The student is asking about the volume of cement needed to fill a form with specified dimensions. To calculate the volume, we need to use the formula for the volume of a rectangular prism, which is length x width x height. In this case, we need to convert the mixed number into an improper fraction before multiplying, or we could convert it to a decimal.

First, convert the length from 40 1/2 inches to 40.5 inches. Then, use the formula:

Volume = length x width x height

Volume = 40.5 in x 10 in x 8 in

Volume = 405 in x 8 in

Volume = 3240 cubic inches

Therefore, to fill the form, 3240 cubic inches of cement is needed.

Social Studies rate, S = 30/ 1.5 = 20pages/hr

Novel rate, N = 150/2 = 75pages/hr

Novel rate as a % of Social Studies rate...

N/S × 100% = 75/20 × 100% = 375%

percent of Ellie’s social studies reading rate is her Novel reading rate is 375%.

What are mathematics operations?

A mathematical operation is a function that converts a set of zero or more input values (also called "b" or "arguments") into a defined output value. The number of operands determines the operation's arity. Most commonly studied operations are binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive and multiplicative inverses.

• Zero-arity operations, or nullary operations, are constants, and mixed products are arity three operations, or ternary operations.

Here, it is given that :

Ellie read 30 pages of her social studies book in 1.5 hours at a constant rate, let first find Ellie's social studies reading rate :

rate = 30 pages/1.5 hours = 20 pages/ hr.

Now, to find out the unit rate, divide the total number of pages reading novel by the total time spent.

rate = 150 pages/ 2 hours = 75 pages/ hr.

To find out the percentage divide Ellie's novel reading rate by  Ellie's social studies reading rate and multiply by 100

percent of Ellie’s social studies reading rate is her Novel reading rate = 75/20 x 100 = 375%.

Therefore, percent of Ellie’s social studies reading rate is her Novel reading rate is 375%.

Johnny currently owns fewer than 200 records.

Let's denote:
- \( x \) as the number of records Johnny currently owns.

Given:
- Gina has 400 records.
- Johnny would still have fewer than Gina has if he were to double the number of records he owns.

We can set up the following inequality:

[tex]\[ 2x < 400 \][/tex]

To find the maximum value of \( x \), we solve for it:

[tex]\[ x < \frac{400}{2} \]\[ x < 200 \][/tex]

So, Johnny currently owns fewer than 200 records.

Answer:

Step-by-step explanation:

Let "e" represent the number of pounds of Earl Grey tea required for the mix. Then (600-e) is the number of pounds of Orange Pekoe tea required. The total cost of the mix is ...

  6·e + 4·(600 -e) = 4.50·600

  2e = 600·(4.50 -4.00) . . . . . simplify, subtract 4·600

  e = 300/2 = 150 . . . . . . . . . . divide by the coefficient of x

Required are 150 pounds of Earl Grey and 450 pounds of Orange Pekoe.

The amount of Earl Grey and Pekoe tea required for the new blend is :

Price of new blend per pound = $4.50

Price per pound of Earl tea = $6

Price per pound of Pekoe tea = $4

Let :

Pound of Earl tea = a

Pound of Pekoe tea = b

Converting the information to Mathematical expressions :

From (1):

a = 600 - b

Put a = 600 in (2)

6(600 - b) + 4b = 2700

3600 - 6b + 4b = 2700

Collect like terms :

-6b + 4b = 2700 - 3600

-2b = -900

b = 900 ÷ 2

b = 450

Recall :

a = 600 - b

a = 600 - 450

a = 150

Answer:

[tex]\large\boxed{15x+42-8y+20-4x=11x-8y+62}[/tex]

Step-by-step explanation:

[tex]15x+42-8y+20-4x\\\\\text{combine like terms}\\\\=(15x-4x)-8y+(42+20)\\\\=11x-8y+62[/tex]

You add like terms together.

Ex. You would add 15x and(-4x) together, giving you 11x

So to simplify it, you need to do 15x-4x, 42+20, and 8y would be left by itself since there are no like terms for 8y.

So the simplified version would be: 11x+62+8y

Answer:

D

Step-by-step explanation:

We will solve the equation by using quadratic formula.

x=  (-b ± √(b^2-4ac))/2a

The standard form of quadratic equation is:

ax^2+bx+c=0

So by comparing with the standard form, we get:

a=1

b= -4

c=18

Putting the values in the formula

x=  (-(-4)± √((-4)^2-4(1)(18)))/2(1)  

x =  (4± √(16-72))/2

x =  (4± √(-56))/2

The minus sign in square root will introduce the imaginary symbol.  

x =  (4± √(14*4*(-1)))/2

The minus 1 can be replace by the imaginary i => i^2 = -1

x =  (4± √(14*2^2*i^2 ))/2

The terms with squares can be brought out of the square root

So,

x =  (4± 2i√14)/2

Taking 2 as common

x =  (2(2± i√(14)))/2

x = 2± i√14

Step-by-step explanation:

we know that

The area of rectangle is equal to

[tex]A=LW[/tex]

we have

[tex]A=56\ cm^{2}[/tex]

so

[tex]56=LW[/tex] ------> equation A

[tex]L=x+2[/tex] -----> equation B

[tex]W=2x-5[/tex] -----> equation C

Substitute equation B and equation C in equation A

[tex]56=(x+2)(2x-5)[/tex]

solve for x

[tex]56=(x+2)(2x-5)\\56=2x^{2}-5x+4x-10\\2x^{2}-x-66=0[/tex]

The formula to solve a quadratic equation of the form [tex]ax^{2} +bx+c=0[/tex] is equal to

[tex]x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}[/tex]  

in this problem we have

[tex]2x^{2}-x-66=0[/tex]  

so

[tex]a=2\\b=-1\\c=-66[/tex]

substitute in the formula

[tex]x=\frac{1(+/-)\sqrt{-1^{2}-4(2)(-66)}} {2(2)}[/tex]

[tex]x=\frac{1(+/-)\sqrt{529}} {4}[/tex]

Answer:

NO

Step-by-step explanation:

To find if they are equivalent, we need to simplify them first.

Using the distributive property we get:

6(4x-5) = 24x - 30

In this case we need to combine like terms.

3 + 22x - 33 - 2x =  20x - 30

So now we can compare.

24x - 30 ≠ 20x - 30

So we can conclude that the two expressions are not equal because 24x - 30 and 20x - 30 are obviously not equal.

Answer:

Not equivalent

Step-by-step explanation:

We are given an expression [tex] 6 ( 4 x - 5 ) [/tex] and we are to check if it is equal to [tex] 3 + 22 x - 33 - 2 x [/tex] or not.

Evaluation the given expression first:

[tex] 6 ( 4 x - 5 ) = 24 x - 30 [/tex]

While adding the terms in [tex] 3 + 22 x - 33 - 2 x [/tex], we get:

[tex] 22 x - 2 x - 33 + 3 = 20 x - 30 [/tex]

[tex] 24 x - 30 \neq 20 x - 30 [/tex]

Therefore, [tex] 6 ( 4 x - 5 ) [/tex] is not equivalent to [tex] 3 + 22 x - 33 - 2 x [/tex].

Final answer:

The density of the laptop is calculated by dividing the mass (2,300 grams) by the volume (2,850 cubic centimeters), resulting in a density of 0.807 g/cm³, which is approximately 46/57.

Explanation:

To find the density of the laptop in grams per cubic centimeter (g/cm³), we use the formula density = mass/volume. The mass of the laptop is given as 2,300 grams and the volume is given as 2,850 cubic centimeters. By substituting into the formula:

Density = Mass / Volume = 2,300g / 2,850cm³ = 0.807 g/cm³.

When expressed as a fraction in simplest form, this is approximately 46/57 (since 0.807 ≈ 46/57). Hence, the answer is D. 46/57.
