Step-by-step explanation:
Plug it in
f(x)=2^x+3
f(2)=2^2+3
f(2)=4+3
f(2)=7
If this helps please mark as brainliest
Answer:
f(2) = 7
Step-by-step explanation:
The answer is found by plugging in the value of f(2) in to the equation for f(x):
f(2) = 2^(2) + 3
First calculate the exponents.
f(2) = 4 + 3
Then simplify.
f(2) = 7

Answer:
#5 - C
#7 - A
Step-by-step explanation:
If two items are similar, it means that the angles and figure itself have not changed, just the size. The two objects are prototional to each other.
In order to find the length of one side, we have to find what the size difference is, if that makes sense. We have to figure out the number that the smaller size is multiplied by in order to get the bigger number (or the other way around).
#5:
Side LK and side DE are preportional. We can divide 35 by 10 to figure out the proportion size. 35/10=3.5. Then we can take that and use it to find the other side. MK and FD are proportional. We can now take 22 and multiply it by 3.5 to get the new side length. 22x3.5=77
#7:
Same thing. 12/8=1.5, which is the proportional size change. We can now take the already exisiting number and multiply it. 5x1.5=7.5

Part 1
Answer: (x+5)(x+10) - 50 = 126Other answers are possible.
-------------
Explanation:
The old width was 5, but then it increases to x+5. The old length was 10, but now it's x+10.
The area of any rectangle is length times width.
So the area of the larger rectangle is (x+5)(x+10). Subtract off the old area of 5*10 = 50 and we get (x+5)(x+10) - 50 as the area of the L shape. Set this equal to 126 to finish setting up the equation. This is one possible answer out of many others. This is because we could expand out the (x+5)(x+10) into x^2+10x+5x+50 or simplify that to x^2+15x+50, as two possible options.
==========================================================
Part 2
Answer: x = 6-------------
Explanation:
Solve the equation we set up in the previous part
(x+5)(x+10) - 50 = 126
x^2+10x+5x+50-50 = 126
x^2+15x = 126
x^2+15x-126 = 0
Apply the quadratic formula from here
[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-(15)\pm\sqrt{(15)^2-4(1)(-126)}}{2(1)}\\\\x = \frac{-15\pm\sqrt{729}}{2}\\\\x = \frac{-15\pm27}{2}\\\\x = \frac{-15+27}{2} \ \text{ or } \ x = \frac{-15-27}{2}\\\\x = \frac{12}{2} \ \text{ or } \ x = \frac{-42}{2}\\\\x = 6 \ \text{ or } \ x = -21\\\\[/tex]
Another method you could use is factoring, so you could say:
x^2+15x-126 = 0
(x-6)(x+21) = 0
x-6 = 0 or x+21 = 0
x = 6 or x = -21
The issue with this is that it may take a while to do this trial and error approach.
Whichever method you used, you'll end up with two solutions. One of those solutions doesn't make sense though. We can't have a negative length or distance value, so we ignore x = -21.
The only practical solution is x = 6
If x = 6, then the old height goes from 5 to x+5 = 6+5 = 11
If x = 6, then the old length goes from 10 to x+10 = 6+10 = 16
The new larger rectangle is 11*16 = 176 sq ft, in which we subtract off the 50 sq ft to get 176-50 = 126 sq ft, and this matches with the 126 given to us. Therefore, the answer is confirmed.

Solve the following system. y = 2x2 - 3x - 4 and y + x = 8. Enter the solution with the smaller x value first. The solutions are ( , ) and ( , )
The solutions of the nonlinear system of equations are the points (x₁, y₁) = (- 2, 10) and (x₂, y₂) = (3, 5).
How to solve a system of algebraic equationsWe find in this place a non-linear system formed by a quadratic equation and a linear equation, which can be solved by algebra properties. The complete procedure is shown below:
y = 2 · x² - 3 · x - 4 (1)
y + x = 8 (2)
By (2) in (1):
2 · x² - 3 · x - 4 + x = 8
2 · x² - 2 · x - 12 = 0
2 · (x² - x - 6) = 0
2 · (x - 3) · (x + 2) = 0
x = 3 ∨ x = - 2
y = 8 - 3 ∨ y = 8 - (- 2)
y = 5 ∨ y = 10
The solutions of the nonlinear system of equations are the points (x₁, y₁) = (- 2, 10) and (x₂, y₂) = (3, 5).

What is a rectangle?A rectangle is a 2-D shape with length and width.
The length and width are different.
If the length and width are not different then it is a square.
The area of a rectangle is given as:
Area = Length x width
We have,
The area of the first fabric scrap is:
A = width x length
A = (2x)(5x)
A = 10x²
The area of the entire quilt is 5 feet wider and 3 feet longer than the first fabric scrap.
Therefore, the width of the quilt is (2x + 5) feet and the length is (5x + 3) feet.
So, the area of the quilt.
A = width x length
A = (2x + 5)(5x + 3)
A = 10x² + 16x + 15
Therefore,
The function that gives the area, f(x), of the quilt in square feet is
f(x) = 10x² + 16x + 15

g(7) = [tex]\frac{7}{8}[/tex] × 7 - [tex]\frac{1}{2}[/tex]

Find the surface area of the composite figure.
Answer:
470
Step-by-step explanation:
there are several surface areas.
1. the 4 side walls of the big block = 4*12*7 = 336
2. top and bottom of the big block = 2* 7*7 = 98
3. subtract the small rectangular area from the top area covered by the small block = 2*7 = 14
4. the 3 (visible) side walls of the small block on top =
3* 2*7 = 42
5. the small top and bottom areas of the small block =
2* 2*2 = 8

Find the length side of W
Answer:
17.99
Step-by-step explanation:
Trig Ratios:
Sin = Opposite over Hypotenuse
Cos = Adjacent over Hypotenuse
Tan = Opposite over Tangent
We can use trig ratio sine as we are given an angle ( 40° )and the hypotenuse (28) and we need to find its opposite side (w)
Recall that sin = opposite over hypotenuse
That being said we want to create an equation to solve for w
[tex]sin(40)=\frac{w}{28}[/tex]
Now we solve for w
Step 1 multiply each side by 28
[tex]\frac{w}{28} *28=w\\sin(40)*28=28sin(20) = 17.99[/tex]
we're left with w = 17.99

a) there are 12 face cards and 52 in the deck
b) half the cards are red, the other half black
c) one queen in each of four suits
d) the deck is broken up into 4 equal suits (hearts, diamonds, spades, clubs) so there are 13 of each.
e) like the answer in part C, there is one of each card in each of the four suits. that gives us four aces and four tens.
