Answer:

its ok I will give you a hand here

Let's solve your equation step-by-step.

(x+2)(x+2)=3x

Step 1: Simplify both sides of the equation.

x2+4x+4=3x

Step 2: Subtract 3x from both sides.

x2+4x+4−3x=3x−3x

x2+x+4=0

For this equation: a=1, b=1, c=4

1x2+1x+4=0

Step 3: Use quadratic formula with a=1, b=1, c=4.

Step-by-step explanation:

So, the equation of the axis of the segment AB is (A) y = 1/2 - x/2.

What is slope?

In mathematics, slope refers to the steepness or incline of a line on a graph. It is a measure of how much the dependent variable changes for every unit change in the independent variable.

The slope of the line passing through points A and B can be calculated as follows:

slope = (change in y) / (change in x) = (1-0) / (1-0) = 1/1 = 1

The equation of a line in slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept.

To find the y-intercept, we can use point A (0,0) and substitute the slope value.

y = mx + b

0 = 1(0) + b

b = 0

Therefore, the equation of the line passing through points A and B is:

y = 1x + 0

Simplifying, we get:

y = x

So, the answer is (A) y = 1/2 - x/2. However, this is not one of the given answer choices. We can also write the equation in point-slope form as y - y1 = m(x - x1) using point A, which gives:

y - 0 = 1(x - 0)

y = x

This confirms our earlier answer.

Bryan invested $1600 in the first account (earning 11% interest) and $4900 (6500 - 1600) in the second account (earning 7% interest).

Let's assume that Bryan invested an amount of x dollars in the first account, which earns 11% interest, and (6500 - x) dollars in the second account, which earns 7% interest.

The interest earned from the first account can be calculated as 0.11x, and the interest earned from the second account can be calculated as 0.07(6500 - x).

According to the problem, the total interest earned after one year is $519. So we can set up the equation:

0.11x + 0.07(6500 - x) = 519

Simplifying the equation:

0.11x + 455 - 0.07x = 519

0.04x + 455 = 519

0.04x = 64

x = 64 / 0.04

x = 1600

Therefore, Bryan invested $1600 in the first account (earning 11% interest) and $4900 (6500 - 1600) in the second account (earning 7% interest).

Answer:

\(\dfrac{dV}{dt}=502.65\ mm^3/s\)

Step-by-step explanation:

The volume of a sphere is given by :

\(V=\dfrac{4}{3}\pi r^3\)

The rate of change of volume means,

\(\dfrac{dV}{dt}=\dfrac{d}{dt}(\dfrac{4}{3}\pi r^3)\\\\\dfrac{dV}{dt}=\dfrac{4}{3}\pi \times 3r\times \dfrac{dr}{dt}\)

We have, \(\dfrac{dr}{dt}=2\ mm/s\ and\ r=40\ mm\)

So,

\(\dfrac{dV}{dt}=\dfrac{4}{3}\pi \times 3\times 20\times 2\\\\=502.65\ mm^3/s\)

So, the volume is increasing at the rate of \(502.65\ mm^3/s\).

Answer:

Step-by-step explanation:

To simulate the outcome of guessing the answers to a 25-question test with three answer choices, you can use a binomial distribution model. The binomial distribution models the probability of getting a certain number of successes (correct answers) in a fixed number of trials (test questions), given a fixed probability of success (probability of guessing the correct answer).

Here's how you could use a binomial distribution model to simulate the outcome of guessing on a 25-question test:

Define the parameters:

n: the number of trials (test questions), which is 25 in this case

p: the probability of success (guessing the correct answer), which is 1/3 or 0.33 in this case

x: the number of successes (number of correct answers)

Use a random number generator to simulate each trial (question) as a Bernoulli trial, which has a probability of success of p. If the random number generator generates a number between 0 and 0.33, count it as a success (correct answer), otherwise count it as a failure (incorrect answer).

Repeat step 2 for each trial (question) in the test.

Repeat steps 2 and 3 a large number of times (e.g., 10,000) to get a distribution of the number of correct answers for the 25-question test.

Use the distribution of correct answers to calculate the probability of getting a certain number of correct answers (e.g., the probability of getting 10 or more correct answers).

By simulating the guessing process using a binomial distribution model, you can estimate the probability of getting a certain number of correct answers on a 25-question test by guessing.

The simplified expression in mathematical form is -45.36.

What is an expression?

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

The expression given is -

(-15 + (-1.6 + 9.34) / 6) × (3² - 5.7)

Simplifying the terms inside the parentheses first, we get -

(-15 + 7.74 / 6) × (9 - 5.7)

Next, we simplify 7.74 / 6 by dividing the numerator by the denominator -

(-15 + 1.29) × (9 - 5.7)

We add -15 and 1.29 inside the first set of parentheses -

(-13.71) × (9 - 5.7)

We subtract 5.7 from 9 inside the second set of parentheses -

(-13.71) × 3.3

Multiplying these two terms, we get -

-45.363 ≈ -45.36

Therefore, the value is obtained as -45.36.

The measure of side length EF in the right triangle is 24.

The Pythagorean theorem states that the "square on the hypotenuse of a right-angled triangle is equal in area to the sum of the squares on the other two sides.

It is expressed as;

c²  = a² + b²

From the diagram:

Hypotenuse DE = c = 26

Leg DF = a = 10

Leg EF = b = ?

Plug in the values and solve for b:

c²  = a² + b²

26²  = 10² + b²

676  = 100 + b²

b² = 676  - 100

b² = 576

b = +√576 ( we take the positive value since we are dealing with dimensions)

b = 24

Therefore, the length EF is 24.

Option C)24 is the correct answer.

It is not possible to find a combination using addition and multiplication of the given single-digit numbers that totals exactly 100 while keeping the same order.

To combine the single-digit numbers 1, 2, 3, 4, 5, 6, 7, 8, and 9 using only addition and multiplication so that they total 100 while keeping the same order, we can form the following expression:

1 + 2 + 3 + 4 + 5 + 6 + 78 + 9

In this expression, we group the numbers 7 and 8 together to form 78. Then, we add all the other numbers from 1 to 6 and the number 9. Adding them up, we get:

1 + 2 + 3 + 4 + 5 + 6 + 78 + 9 = 108

Unfortunately, the sum obtained from this expression is 108, not 100 as required.

It is not possible to obtain a sum of exactly 100 by combining the single-digit numbers 1 to 9 in the given order using only addition and multiplication. This is because the largest single-digit number, 9, is relatively small compared to the desired total of 100.

Adding all the single-digit numbers in order without any multiplication would result in a sum of 45, which is significantly lower than 100. Multiplication can only further decrease the sum, making it even more difficult to reach 100.
