The value of the given expression 5² + 2³ is 33
What are expressions?An expression is a sentence with at least two numbers or variables having mathematical operation. Math operations can be addition, subtraction, multiplication, division.
For example, 2x+3
The given expression, 5² + 2³, involves two operations: squaring and cubing.
The first operation, 5², means that we need to multiply 5 by itself, which results in 25.
The second operation, 2³, means that we need to multiply 2 by itself three times, which results in 8.
Therefore, 5² + 2³ is equivalent to 25 + 8, which gives us 33 as the final answer.
In other words, the value of the given expression is 33. This calculation involves basic arithmetic operations and can be easily solved using a calculator or mental math skills.

Solve for m:
13=2m+5
Please explain how you figured this out.
Answers
8 = 2m
m = 4
EXPLANATION:
we have to break the equation down to find m. so, first, we take care of the 5. you can subtract 5 from the right side and what you do to the right, you have to do to the left.
this gives you 8 = 2m
next, we have to get rid of the 2 in order to only have an m. this means we have to divide m and 2. and remember, what you do to one side, you have to do to the other.
so, you do 2m divided by 2, giving you m and 8 divided by 2 giving you m = 4!!

What number would you multiply the second equation by in order to eliminate the x-terms when adding to the first equation? What number would you multiply the first equation by in order to eliminate the y-terms when adding to the second equation?
Answers
Answer:
1. Multiply (2) by 2 to eliminate the x-terms when adding
2. Multiply (2) by 3 to eliminate the y- term
Step-by-step explanation:
Use this system of equations to answer the questions that follow.
4x-9y = 7
-2x+ 3y= 4
what number would you multiply the second equation by in order to eliminate the x-terms when adding the first equation?
4x-9y = 7 (1)
-2x+ 3y= 4 (2)
Multiply (2) by 2 to eliminate the x-terms when adding the first equation
4x-9y = 7
-4x +6y = 8
Adding the equations
4x + (-4x) -9y + 6y = 7 + 8
4x - 4x - 3y = 15
-3y = 15
y = 15/-3
= -5
what number would you multiply the second equation by in order to eliminate the y- term when adding the second equation?
4x-9y = 7 (1)
-2x+ 3y= 4 (2)
Multiply (2) by 3 to eliminate the y- term
4x - 9y = 7
-6x + 9y = 12
Adding the equations
4x + (-6x) -9y + 9y = 7 + 12
4x - 6x = 19
-2x = 19
x = 19/-2
= -9.5
x = -9.5

Answer:
[tex]\displaystyle h=-\frac{1}{6}x^2+2x[/tex]
Step-by-step explanation:
We are given that the height of the tunnel is modeled by:
[tex]h=rx^2+tx[/tex]
Where r and t are constants.
We are also given that the maximum height of the tunnel h is six meters.
And at ground level, the width is 12 meters.
And we want to determine the equation of the parabola.
First, since this is a quadratic, our maximum height h will occur at the vertex of our equation.
Recall that the vertex is given by the formulas:
[tex]\displaystyle \text{Vertex} = \left(-\frac{b}{2a}, f\left(-\frac{b}{2a}\right)\right)[/tex]
In our case, we have the function:
[tex]h=(r)x^2+(t)x[/tex]
Hence, a = r; b = t; and c = 0.
Therefore, the x-coordinate of our vertex is:
[tex]\displaystyle x = -\frac{t}{2r}[/tex]
Therefore, if we substitute this back into our equation, the result should be six since six is the maximum height. Hence:
[tex]\displaystyle (6)=r\left(-\frac{t}{2r}\right)^2+t\left(-\frac{t}{2r}\right)[/tex]
Simplify:
[tex]\displaystyle 6=r\left(\frac{t^2}{4r^2}\right)-\frac{t^2}{2r}[/tex]
Simplify:
[tex]\displaystyle 6=\frac{t^2}{4r}-\frac{t^2}{2r}[/tex]
Subtract:
[tex]\displaystyle 6=\frac{t^2}{4r}-\frac{2t^2}{4r} = -\frac{t^2}{4r}[/tex]
Multiply:
[tex]\displaystyle 24r=-t^2, \, r\neq 0[/tex]
Solve for r:
[tex]\displaystyle r=-\frac{t^2}{24}[/tex]
Next, we are given that the width is 12 meters at ground level.
Hence, when h = 0, the difference of our roots is 12:
We have:
[tex]0=rx^2+tx[/tex]
Factor:
[tex]0=x(rx+t)[/tex]
By the Zero Product Property:
[tex]x=0\text{ or } rx+t=0[/tex]
Hence, the first zero is 0.
Therefore, the second zero must be 12 to ensure that our width is 12.
Let's isolate the second zero. Subtract t from both sides:
[tex]rx=-t[/tex]
Divide both sides by r:
[tex]\displaystyle x=-\frac{t}{r}[/tex]
We know that this zero must be 12. Thus:
[tex]\displaystyle 12=-\frac{t}{r}[/tex]
We have previously solved for r. Substitute:
[tex]\displaystyle 12=-\frac{t}{-\dfrac{t^2}{24}}[/tex]
Simplify:
[tex]\displaystyle 12=\frac{24}{t}[/tex]
Take the reciprocal of both sides:
[tex]\displaystyle \frac{t}{24}=\frac{1}{12}[/tex]
Multiply. Hence, the value of t is:
[tex]t=2[/tex]
Find r. Recall that:
[tex]\displaystyle r=-\frac{t^2}{24}[/tex]
Therefore:
[tex]\displaystyle r=-\frac{(2)^2}{24}=-\frac{4}{24}=-\frac{1}{6}[/tex]
Then in conclusion, our equation will be:
[tex]\displaystyle h=-\frac{1}{6}x^2+2x[/tex]
I am thinking of two numbers. Their sum is 1776 and their difference is 1492. What are the numbers?
Answers
Answer:
1634 and 142
Step-by-step explanation:
y+x=1776
- (y-x=1492)
equals:
2x=284
÷2 ÷2
x=142
y+142=1776
-142 -142
y=1634
First number and second number are 1,634 and 142.
Given that;
Difference of two number = 1,492
Sum of two number = 1,776
Find:
The numbers
Computation:
Assume numbers are 'a, b'
So,
a + b = 1776 ...... eq1
a - b = 1492 ...... eq2
Eq 1 - Eq2
2b = 284
b = 142
a + b = 1776
a + 142 = 1776
a = 1,634

3/4
Step-by-step explanation:
Answer:
The answer is 3/4.
Step-by-step explanation:
1/2+1/4
First we want to get a common denominator so that they can be added together.
1/2 * 2/2 = 2/4
We multiplied 1/2 by 2/2 so that both terms have a denominator of 4. Note that we also multiplied the top and bottom of 1/2 because we have to keep the value of the fraction the same.
Now we just add the fractions together.
2/4 + 1/4 = 3/4
So 3/4 is the answer. It is already in its simplest form meaning it cannot be simplified further.
