4x^2 - 25 < 0 inequality

Answers

Answer 1

Answer:

x∈(−25,25)

SOLUTION STEPS

4x2−25<0

Add 425 to both sides.

x2<425

Calculate the square root of 425 and get 25. Rewrite 425 as (25)2.

x2<(25)2

Inequality holds for ∣x∣<25.

∣x∣<25

Rewrite ∣x∣<25 as x∈(−25,25).

x∈(−25,25)

Answer 2

Answer:  x > 5/4

First, add 25 to both sides

4x² < 25

Then take the square root

4x < 5

Finally, isolate the variable by dividing by 4

x < 5/4

Because you divided, the sign gets flipped

x > 5/4

Based on the graph above, estimate to one decimal place the average rate of change from x=1 to x=3 (Blank).

Explain!

Thanks!

Answers

The average rate of change from x=1 to x=3 is -1

How to find the average rate of change from x=1 to x=3?

On the given graph, we have the following function values

f(1) = 6

f(3) = 4

The average rate of change from x=1 to x=3 is then calculated as

Rate = [f(3) - f(1)]/[3 - 1]

This gives

Rate = [4 - 6]/[3 - 1]

Evaluate

Rate = -1

Hence, the average rate of change from x=1 to x=3 is -1

chan is filling a box with 1 inch cubes. he filled the bottom layer with 5x1 inch cubes long, and 4x1 inch cubes wide. The box is 6 inches tall.

Answers

Answer:

  120 cubes will fill the box

Step-by-step explanation:

You want to know the number of 1-inch cubes it takes to fill a box that is 5 cubes long, 4 cubes wide, and 6 inches tall.

Layer

To cover the bottom of the box, Chan needs to make an array of cubes that has 4 rows with 5 cubes in each row. That layer will have ...

  4 × 5 = 20 . . . . cubes per layer

Volume

Each layer occupies 1 inch of height, and the box is 6 inches high. The volume of the box will be filled with six of these layers. That will take this many cubes:

  (6 layers) × (20 cubes/layer) = 6 × 20 cubes = 120 cubes

Chan will need 120 cubes to fill the box.

The equation is given as

9x - 7 = 3(3x + 2)

Open the bracket in the above equation

So, we have

9x - 7 = 9x + 14

Subtract 9x from both sides of the equation

So, we have

In the lab, Miguel has two solutions that contain alcohol and is mixing them with each other. He uses twice as much Solution A as Solution B. Solution A is 12% alcohol and Solution B is 16% alcohol. How many milliliters of Solution B does he use, if the resulting mixture has 120 milliliters of pure alcohol? Number of milliliters of Solution B: X Ś​

Answers

Miguel uses 300 mL Solution B and 600 mL Solution A.

What is termed as the percentages?A percentage is a relative value that symbolizes the hundredth part of any quantity.One percent (symbolized 1%) is one hundredth part; thereby, 100 percent symbolizes the entire amount as well as 200 percent clarifies twice the given amount.

Let x represent the amount of Solution B used.

2x = the quantity of Solution A used.

Solution A is alcohol = 12%.

Solution B is alcohol = 16%.

Given that 12% = 0.12 and 16% = 0.16, we can calculate the following equation:

2x(0.12) + x(0.16) = 120 (Recall that pure alcohol has a concentration of 100% = 1.00.)

0.24x + 0.16x = 120

0.40x = 120

x = 300 mL

Thus, Miguel  makes use of 300 mL of Solution B and 2(300) = 600 mL of Solution A.

What is the experimental probability that the next person to sign up will have blue eyes?
Write your answer as a fraction or whole number.
P(blue)=

Answers

The experimental probability of next person to have Blue eyes is 3/7.

Probability :

Probability is the branch of mathematics that studies the possible outcomes of given events together with the outcomes' relative likelihoods and distributions.

It is based on the possible chances of something to happen.

Probability (P) = Number of a Favourable outcome {n (E)} / Total number of outcomes {n (S)}  

Simply,  P = n (E) / n (S)

Given, Eye colors of the people

Green = 2

Blue    = 30

Brown = 38

To find the probability of next person to have blue eyes, first we will add the given eye colors

Total number of Eye Colors = 2 + 30 + 38 = 70

Number of Blue Eyes = 30

Then, Probability to have blue eyes P(blue) = Number of Blue Eyes / Total number of Eye Colors

                                                      = 30/70

                                                      = 3/7

So, there is 3/7 chances to next person to have blue eyes.

4b.) 0.0025 = 2.5 x 10 to the exponent -3

5a.) 2 x 10 to the exponent -2 = 0.02

5b.) 16 x 10 to the exponent -4 = 0.0016

Tip:

The number being multiplied has to be less than or equal to 10. Count the places the decimal point moves from the end of the number to the number in the original equation.

Example: 0.05 = 5 x 10 to the exponent -2

0.05 has 2 spaces for the decimal point to move up to 5 going right. We use a negative decimal because 0.05 is less than 5. Here is an example where the exponent is positive:

5000 = 5 x 10 to the exponent 3

5000 has 3 spaces for the decimal point to move down to 5 going left.

Step-by-step explanation: "Lies between" means that it's in the middle. C is in the middle of A and B. A to C would be the same distance of C to B because C seperates the segments into 2 equal halves. AB is the whole segment including C, you could do AC + AC if you substituted it for the lengths and you would still get AB

Answers

The required expression for the given statement is 4x + 1.

What is an expression?

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

The given statement is,

the difference between nine times a number and one more than five times the number

Let x be the number.

Thus, we have

nine times a number = 9x

one more than five times the number = 1 - 5x

Thus, the numerical expression we get is

9x + (1 - 5x)

Expanding we get

9x + 1 - 5x

Solving we get

4x + 1

this is the required expression

Thus, the required expression for the given statement is 4x + 1.
