Answer:
c. 45°
Step-by-step explanation:
The figure is rotated about 45° counterclockwise, so the angle is +45°.
Answer:
\(45\)
Step-by-step explanation:
In this case, we take as reference points A and point A'. The point A' is "right under" point P if we draw a line between them. So we can draw another horizontal line that passes through point P that is perpendicular to the line that we first drew. This would give a pair of reference axis to which we will measure the angle of rotation.
Note first that to map point A to point A', we necessarily need to move the triangle in a counterclockwise manner. This, by definition, means that we are doing a rotation by a positive angle. This discards the first two possible options
Now, using the lines that joins the point P and A as reference. We can see that the angle between this line and the black horizontal line and the angle between this line and the black vertical lines is the same. This means that the line PA is splitting the angle between this two lines in exactly the same measure. Since the angle between the black line is 90°, if x is the measure of the angle between line PA and the vertical black line, we would get that:
\(x + x = 2x = 90\)
So, dividing both sides by 2, we get;
\(x = \frac{90}{2} = 45\)
so,The angle of rotation is 45°

Answer:
B. -414,720 x⁷y⁶
Step-by-step explanation:
To find the 4th term of the expansion of (2x - 3y²)¹⁰, we can use the binomial theorem.
The binomial theorem states that for an expression of the form (a + b)ⁿ:
\(\displaystyle (a+b)^n=\binom{n}{0}a^{n-0}b^0+\binom{n}{1}a^{n-1}b^1+...+\binom{n}{r}a^{n-r}b^r+...+\binom{n}{n}a^{n-n}b^n\\\\\\\textsf{where }\displaystyle \rm \binom{n}{r} \: = \:^{n}C_{r} = \frac{n!}{r!(n-r)!}\)
For the expression (2x - 3y²)¹⁰:
a = 2xb = -3y²n = 10Therefore, each term in the expression can be calculated using:
\(\displaystyle \boxed{\binom{n}{r}(2x)^{10-r}(-3y^2)^r}\quad \textsf{where $r = 0$ is the first term.}\)
The 4th term is when r = 3. Therefore:
\(\begin{aligned}\displaystyle &\;\;\;\;\:\binom{10}{3}(2x)^{10-3}(-3y^2)^3\\\\&=\frac{10!}{3!(10-3)!}(2x)^7(-3y^2)^3\\\\&=\frac{10!}{3!\:7!}\cdot2^7x^7(-3)^3y^6\\\\&=120\cdot 128x^7 \cdot (-27)y^6\\\\&=-414720\:x^7y^6\\\\ \end{aligned}\)
So the 4th term of the given expansion is:
\(\boxed{-414720\:x^7y^6}\)

What is the second derivative of -x^3
The second derivative of the function is -6x
What is derivative of a function?Derivative of a function f(x) signifies the rate of change of the function f(x) with respect to x at a point lying in its domain. For a function to be differentiable at any point x = a in its domain, it must be continuous at that particular point but vice-versa is necessarily not always true.
The derivative of a function f(x) is given as; d/dx(fx)
f(x) = -x³
d/dx = 3(-x)³⁻¹
d/dx = -3x²
For the second derivative, we would derivate the function the second time.
d²/dx² = d/dx(-3x²)
d²/dx² = 2 * (-3x)
d²/dx² = -6x

The doubling time after 4 and 7 years is 400 months and 700 months respectively
How to determine the doubling timeThe formula for finding doubling time is given as;
Doubling time = \(t \frac{In 2}{In 1 + \frac{r}{100} }\)
Where t = time = 4 and 7 years
r = rate
For 4 years, we have
Doubling time = \(4 * \frac{In 2}{In ( 1 + \frac{0.7}{100}) }\)
⇒ \(4 * \frac{In 2}{In 1. 0074}\)
⇒ \(4 * \frac{0. 6931}{0. 0074}\)
⇒ \(4\) × \(93. 66\)
⇒ 374. 65
⇒ 400 months in the nearest hundredth
For 7 years
⇒ \(7\) × \(93. 66\)
⇒ \(655. 62\)
⇒ 700 months in the nearest hundredth
Thus, the doubling time after 4 and 7 years is 400 months and 700 months respectively

The temperature in a hotel is 21 °C.
The temperature in the hotel is 26,7°C warmer than at the top of the mountain.
The temperature at the top of the mountain is 3.2°C colder than at the bottom of the mountain.
Work out the temperature at the bottom of the mountain.
The temperature at the bottom of the mountain is 50.9 °C.
Let's work through the given information step by step to find the temperature at the bottom of the mountain.
The temperature in the hotel is 21 °C.
The temperature in the hotel is 26.7 °C warmer than at the top of the mountain.
Let's denote the temperature at the top of the mountain as T_top.
So, the temperature in the hotel can be expressed as T_top + 26.7 °C.
The temperature at the top of the mountain is 3.2 °C colder than at the bottom of the mountain.
Let's denote the temperature at the bottom of the mountain as T_bottom.
So, the temperature at the top of the mountain can be expressed as T_bottom - 3.2 °C.
Now, let's combine the information we have:
T_top + 26.7 °C = T_bottom - 3.2 °C
To find the temperature at the bottom of the mountain (T_bottom), we need to isolate it on one side of the equation. Let's do the calculations:
T_bottom = T_top + 26.7 °C + 3.2 °C
T_bottom = T_top + 29.9 °C
Since we know that the temperature in the hotel is 21 °C, we can substitute T_top with 21 °C:
T_bottom = 21 °C + 29.9 °C
T_bottom = 50.9 °C
Therefore, the temperature at the bottom of the mountain is 50.9 °C.
