WILL GIVE BRAINLIEST AND THANKS. find the value of x
Answer:
x = 48
Step-by-step explanation:
To solve this problem, one must assume that the segment with a length of (7) bisects the segment with a length of (x).
It is given that the segment with a length of (7) is perpendicular (forms a right angle with) the segment that has a length of (x). This is indicated by the box around one of the angles, signifiying that it is a right angle, or (90) degree angle. Therefore, the triangle with sides measuring (25) and (7) is a right triangle. Thus, one can use the Pythagorean theorem to solve for the base length. Then multiply it by (2) to find the total length of (x).
The Pythagorean theorem states the following:
[tex]a^2+b^2=c^2[/tex]
Where (a) and (b) are the legs, or sides adjacent to the right angle, and (c) is the hypotenuse or side opposite the right angle.
[tex]a^2+(7)^2=(25)^2[/tex]
Simplify,
[tex]a^2+49=625[/tex]
Inverse operations,
[tex]a^2=576\\\\a=24[/tex]
Multiply this value by (2) to find the total side length of the segment (x),
2(a)
Substitute,
2(24)
Simplify,
48

What is the area of figure ABCD?
A
104 square inches
B
120 square inches
C
136 square inches
D
168 square inches
Answer:
That's a Trapezium
Area =½( A + B)x H
A and B are the top and bottom of the shape.
H is the height.
Substituting...
Area = ½(13+17)8
=120 Square Inches
Answer:
B. 120 in.²
Step-by-step explanation:
13 × 8 = 104 in.²
17 - 13 = 4
4 × 8 = 32
32 ÷ 2 = 16
16 in.² + 104 in.²
120 in.²

Definition of a Derivative: [tex]\displaystyle f'(x)= \lim_{h \to 0} \frac{f(x + h) - f(x)}{h}[/tex]
Step-by-step explanation:
Step 1: Define
Identify
[tex]\displaystyle\displaystyle g(x) = \lim_{h \to 0} \frac{f(x + h) - f(x)}{h}[/tex]
[tex]\displaystyle f(x) = \frac{3}{5x^4 + 3}[/tex]
[tex]\displaystyle g(0)[/tex]
Step 2: Differentiate
Substitute in x [Function g(x)]: [tex]\displaystyle\displaystyle g(0) = \lim_{h \to 0} \frac{f(0 + h) - f(0)}{h}[/tex]Substitute in function f(x) [Function g(x)]: [tex]\displaystyle\displaystyle g(0) = \lim_{h \to 0} \frac{\frac{3}{5(0 + h)^4 + 3} - \frac{3}{5(0)^4 + 3}}{h}[/tex]Simplify: [tex]\displaystyle\displaystyle g(0) = \lim_{h \to 0} \frac{\frac{3}{5h^4 + 3} - 1}{h}[/tex]Rewrite: [tex]\displaystyle\displaystyle g(0) = \lim_{h \to 0} \frac{3}{h(5h^4 + 3)} - \frac{1}{h}[/tex]Rewrite: [tex]\displaystyle\displaystyle g(0) = \lim_{h \to 0} \frac{3}{h(5h^4 + 3)} - \frac{5h^4 + 3}{h(5h^4 + 3)}[/tex][Subtraction] Combine like terms: [tex]\displaystyle\displaystyle g(0) = \lim_{h \to 0} \frac{3 - 5h^4 + 3}{h(5h^4 + 3)}[/tex][Addition] Simplify: [tex]\displaystyle\displaystyle g(0) = \lim_{h \to 0} \frac{-5h^4 + 6}{h(5h^4 + 3)}[/tex][Distributive Property] Distribute h: [tex]\displaystyle\displaystyle g(0) = \lim_{h \to 0} \frac{-5h^4 + 6}{5h^5 + 3h}[/tex]Evaluate limit [Power Method]: [tex]\displaystyle\displaystyle g(0) = 0[/tex]Since the bottom polynomial has a higher degree than the top polynomial, the bottom polynomial will increase faster.
∴ If the bottom is approaching a bigger value, the fraction gets smaller and smaller, approaching 0.

What is the midpoint between( -4,-5 )and( 6,2)
Answer:
(1, -1.5)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the x values and divide by 2
(-4+6)/2 = 2/2 = 1
To find the y coordinate of the midpoint, add the y values and divide by 2
(-5+2)/2 = -3/2 = -1.5

Which value of x will make the following statement false?
*<5.3
A. 16
B. 5.3
C. 0
D. -8.95
Answer:
A [and B]
Step-by-step explanation:
If x < 5.3 then anything higher than 5.3 makes the statement false.
16 is too high and therefore is the most obvious fallacy.
5.3 would actually make x=5.3 and therefore x wouldn't be less than 5.3 making it also false but this really depends on what your teacher is looking for.
0 is true.
-8.95 is true.

Rotate triangle P 90° clockwise about the point (2, -1).
Please screenshot this and send me the answers cuz I really need help :(
Answer: (2,0), (2,1), and (6,1)
Step-by-step explanation: I just used the desmos graphing calculator to find the answer to your problem. I don't know any formulas to solve it so I just rotated the points by hand. I also made sure they were still equidistant from the point (2,-1) because if their distances from other points changed during the rotation, then the triangle would not be equal to the first triangle and the image would've been distorted.
I hope this helps! Have a nice day.

Madeleine owes $36,000 to a private lender. The debt grows with 12% annual interest that compounds every week. How much will Madeleine owe in one year?
Answer:
A= $40584.28
Step-by-step explanation:
P = 36000
r = 12% = 0.12
n = 52 weeks
t = 1
[tex]A = P(1 + \frac{r}{n})^{nt}\\[/tex]
[tex]=36000(1 + \frac{0.12}{52})^{52 \times 1}\\\\=36000 (1.002307)^{52}\\\\=36000 \times 1.12734\\\\=40584.28[/tex]

Shaan walks 2.5 meters per second. His brother Dhvan walks 1 meter
per second. Dhvan wants to have a race. Shaan knows that he walks faster,
but he wants to give his brother a head start of 45 meters, so it doesn't
seem that he is allowing him to win. How many meters long should the
race be in order for Dhvan to win?
Answer:
The race must be up to 29 meters for Dhvan to win.
Step-by-step explanation:
Since Shaan walks 2.5 meters per second, while his brother Dhvan walks 1 meter per second, and Dhvan wants to have a race, and Shaan knows that he walks faster, but he wants to give his brother a head start of 45 meters, so it doesn't seem that he is allowing him to win, to determine how many meters long should the race be in order for Dhvan to win the following calculation must be performed:
45 / (2.5 - 1) = X
45 / 1.5 = X
30 = X
Therefore, the race must be up to 29 meters for Dhvan to win.

A triangle has a perimeter of 9x² + 7x - 2.
One side of the triangle measures 6x + 7. Another side of the triangle measures 8x?.
What is the measure of the third side of the triangle?
Answer:
9x² - 7x - 9
Step-by-step explanation:
Two sides
(6x + 7) + 8x = 14x + 7
total perimeter - two sides = Third side
9x² + 7x - 2
- (14x + 7)
––––––––––

What percent chose to make a craft?
Answer:
42% chose to make a craft
Step-by-step explanation:
To find the percentage of something, divide the numerator(21) by the denominator(50) and then multiply by 100
21/50 = 0.42
0.42*100 = 42
Add the percentage sign, and that's your answer.
Help urgent
I need this done quick
Answer:
It is supplementary.
Step-by-step explanation:
Supplementary angles are angles that have two angles adding up to 180°. You can tell by just finding the straight line that equals 180° then seeing a line that separates the whole measurement into two angles, but together making a 180° angle still. Hope this helps! :D
Meanings of the other Options:
Alternate Interior Angles - Angles formed when two parallel or non-parallel lines are intersected by a transversal. The angles are positioned at the inner corners of the intersections and lie on opposite sides of the transversal.
Corresponding Angles - Angles that are in the same relative position at an intersection of a transversal and at least two lines. If the two lines are parallel, then the corresponding angles are congruent.
Alternate Exterior Angles - Angles are the pair of angles that lie on the outer side of the two parallel lines but on either side of the transversal line. Exterior angles lie on opposite sides of the transversal but outside the two parallel lines.
Parallel Lines - Two lines that never intersect. Like an equal sign for example (=).
Transversal - A line the cuts through a parallel line. Like a non-equal sign for example (≠).

Hi there!

Knowing that one cube has side-lengths of 1/2, we can calculate the dimensions for the prism:
Length: 1/2 × 5 = 2.5 cm
Height: 1/2 × 3 = 1.5 cm
Width: 1/2 × 2 = 1 cm
Use this formula to solve for the volume:
V = l × w × h
Thus:
V = 2.5 × 1.5 × 1 = 3.75 cm³
Convert to fraction:
75/100 = 3/4
Thus, the volume in mixed-numbers is 3 3/4 cm³.
