The solution of the quadratic equation (x + 4)^2 = 25 is x = -9 and x = 1
The correct answer is option (C)
What is quadratic equation?"It is a polynomial with degree 2. The general form of quadratic equation is ax²+ b x + c =0, where a, b, c are real numbers with a ≠ 0."
For given example,
We need to find the solution of the quadratic equation (x + 4)^2 = 25.
⇒ (x + 4)^2 = 25
⇒ x² + 2(4)(x) + (4)² = 25
⇒ x² + 8x + 16 = 25
⇒ x² + 8x - 9 = 0
⇒ x² + 9x - x - 9 = 0
⇒ x(x + 9) - 1(x + 9) = 0
⇒ (x + 9)(x - 1) = 0
⇒ x + 9 = 0 and x - 1 = 0
⇒ x = -9 and x = 1
The correct answer is option (C)

Answer:
m(DE) = 90°
Step-by-step explanation:
Since both circles are equal, therefore, their radius would be equal too.
m<S = 180 - right angle (angles on a straight line)
m<S = 180 - 90 = 90°
m<R = m<S (congruent triangles)
m<R = 90°
m<R = m(DE) (central angle = intercepted arc based on the central angle theorem)
Substitute
90° = m(DE)
m(DE) = 90°

What is the slope of AB?
Can anyone help me ??
Answer:
1/2
Step-by-step explanation:
Point A is (2, 3)
Point B is (6, 5)
To get the slope of a line, first select any two points on that line.
Then, take the difference of the y values, and divide it by the difference of the x values. This is also known as the change in y over the change in x, or rise over run.
[tex]\frac{3-5}{2-6} =\frac{-2}{-4} =\frac{1}{2}[/tex]

A cylinder has a height of 7 yards and a radius of 14 yards. What is its volume? Use ≈ 3.14 and round your answer to the nearest hundredth.
The answer to the nearest hundredth, the volume of the cylinder is approximately 4309.28 cubic yards.
To calculate the volume of a cylinder, we can use the formula V = πr²h, where V is the volume, r is the radius, and h is the height.
Radius (r) = 14 yards
Height (h) = 7 yards
Approximation of π = 3.14
Substituting these values into the formula, we have:
[tex]V = 3.14 \times(14^{2} )\times 7[/tex]
First, let's calculate the value of (14²):
[tex]14^{2} = 14 \times 14 = 196[/tex]
Now, substitute the values back into the formula:
[tex]V = 3.14 \times 196 \times 7[/tex]
Next, perform the calculations:
[tex]V = 3.14 \times 1372[/tex]
V ≈ 4309.28

As altitude within the troposphere increases, the amount of water vapor in the atmosphere generally: PLEASE HELP ME!!!
A. decreases, only
B. increases, only
C. remains the same
D. decreases, then increases
As altitude within the troposphere increases, the amount of water vapor in the atmosphere generally decreases.
What happens in the troposphere as you increase in altitude?The bottom of the troposphere, close to ground level, has the warmest air. As one ascends into the troposphere, the air becomes cooler. Because of this, tall mountains' peaks might still have snow on them in the summer. Along with decreasing with altitude, so do air pressure and air density.
As, The troposphere's temperature and water vapour content drop sharply with altitude.
This is because it absorbs solar energy and thermal radiation from the planet's surface, water vapour plays a significant role in controlling the temperature of the atmosphere.
99% of the water vapour in the atmosphere is found in the troposphere.
Thus, the water vapor decreases.

Spinner A and Spinner B have 4 color choices each: grey, orange, blue and yellow. What is the probability of getting a Blue and Grey combination from the area model below?
Answer:
The probability of getting a Blue and Gray combination is 6.25%.
Step-by-step explanation:
Given that Spinner A and Spinner B have 4 color choices each: gray, orange, blue and yellow, to determine what is the probability of getting a Blue and Gray combination from the area model below, the following calculation must be performed:
Blue / Total: 1/4
Gray / Total: 1/4
1/4 = 0.25
0.25 x 0.25 = X
0.0625 = X
0.0625 x 100 = 6.25
Therefore, the probability of getting a Blue and Gray combination is 6.25%.

To construct a compound pulley with an ideal mechanical advantage of 6 you would arrange several fixed and movable pulleys so that a total of ... rope segments were pulling up on the load
Please give correct answer!
Answer:
6.
Step-by-step explanation:
A simple machine can be defined as a type of machine with no moving parts but can be used to perform work.
Basically, a simple machine allows for the transformation of energy into work. The six simple machines are; lever, wedge, inclined plane, screw, wheel and axle, and pulley.
A pulley is typically made up of a wheel and rope which allows force to be multiplied such as in a drawing well.
In order to construct a compound pulley with an ideal mechanical advantage of 6 you would arrange several fixed and movable pulleys so that a total of 6 rope segments were pulling up on the load.
Hence, you need 6 pulley wheels and 6 rope segments to construct a compound pulley with an ideal mechanical advantage of 6.
To find the ideal mechanical advantage;
Mathematically, IMA is given by the formula;
[tex] IMA = \frac {distance \; over \; which \; the \; effort \; is \; applied}{distance \; the \; load \; travels} [/tex]
NB: The ideal mechanical advantage has no units.
