In this problem, we're given an angle and two sides. Therefore, we should use a trigonometric function to solve for x.
Remember! SOH-CAH-TOA
We are given a 26 degree angle, looking from which we have the adjacent side and the hypotenuse. As such, we should use the cosine function.
cos(26) = x / 69

Which of the following expressions is equivalent to ab² + 6ab + 7a³-14a?
a. (b + 7)(b + 6)(a²-2)
b. b(b + 6)+7(a2-2)
c. a[b(b + 6)+7(a²-2)]
d. a[(b + 7)(b + 6)(a²-2)]
Answer:
c. a[b(b + 6)+7(a²-2)]
Step-by-step explanation:
look at the pic
The equivalent expression of the expression ab² + 6ab + 7a³ - 14a is
C. a [b (b + 6) + 7 (a² - 2)]
Option C is the correct answer.
We have,
To find the expression that is equivalent to ab² + 6ab + 7a³ - 14a, we can factor out common terms from the given expression.
The common terms in the expression are "a" and "(b + 7)".
Step 1:
Factor out "a" from the expression:
ab² + 6ab + 7a³ - 14a = a(b² + 6b + 7a² - 14)
Step 2:
Factor the quadratic expression inside the parenthesis:
b² + 6b can be factored as b(b + 6)
7a² - 14 can be factored as 7(a² - 2)
Step 3:
Putting it all together, the equivalent expression is:
a [b (b + 6) + 7 (a² - 2)]
Now let's check which option matches this expression:
a. (b + 7)(b + 6)(a² - 2) - Not equivalent
b. b(b + 6) + 7(a^2 - 2) - Not equivalent
c. a[b(b + 6) + 7(a² - 2)] - Equivalent
d. a[(b + 6)(b + 7a² - 14)] -Not equivalent

Find the dimensions and volume of the right circular cylinder of maximum volume inscribed in a sphere with a radius of 25 cm.
The dimensions of the circular cylinder of maximum volume inscribed in sphere is r = 20.4 cm , h = 28.86 cm.
What is a sphere ?A sphere is a three dimensional round shaped figure , It has no vertices and the distance form the centre to any point on the sphere is same.
It is given that
A right circular cylinder is inscribed in a sphere
The circular cylinder has the maximum volume
Radius of the sphere is 25 cm.
Dimensions of the cylinder = ?
As it is a right cylinder.
The Pythagoras theorem can be applied
r² + (h/2)² = 25²
r² = 625 - h²/4
volume of the cylinder
= πh(625 - h²/4)
= π(625 h - h³/4)
As the volume is maximum ,
so the derivative of the expression = 0
π(625 - 3h²/4) = 0
so h = 50 /√ 3
so r² = 625 - 2500 / (3 *4 )
r = 20.4 cm
h = 28.86 cm
Therefore the dimensions of the circular cylinder of maximum volume inscribed in a sphere is r = 20.4 cm , h = 28.86 cm.

find x and y !
pls help giving 50 points !!
Answer:
y = 20°
x = 35°
Explanation:
Equation's:
1) 2y + x + 105° = 180°
2) 3x + x + 2y = 180°
Make y subject in equation 2
3x + x + 2y = 180
4x + 2y = 180
2y = 180 - 4x
y = 90 - 2x
Insert this into equation 1
2(90 - 2x) + x + 105° = 180°
180 - 4x + x + 105 = 180
-3x = -105
x = 35°
Find value of y
y = 90 - 2x
y = 90 - 2(35)

The average waiting time to be seated for dinner at a popular restaurant is 23.8 minutes with a standard deviation of 6 minutes. What is the probability that 20 people will wait less than 21 minutes? Leave your answer exactly as it is taken from the table.
The probability that 20 customers will wait less than 21 minutes to be seated is
Using the normal distribution, it is found that there is a 0.3192 = 31.92% probability that 20 customers will wait an average of less than 21 minutes to be seated.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].The parameters for this problem are given as follows:
[tex]\mu = 23.8, \sigma = 6, n = 20, s = \frac{6}{\sqrt{20}} = 1.3416[/tex]
The probability that 20 customers will wait an average of less than 21 minutes to be seated is the p-value of Z when X = 21, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem:
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{21 - 23.8}{6}[/tex]
Z = -0.47
Z = -0.47 has a p-value of 0.3192.

Answer:
[tex]1024x^{40}[/tex]
Step-by-step explanation:
So the first step is to add like terms since you can simplify the numerator by adding the two values sine they have the same variable and degree.
Add like terms:
[tex][\frac{8x^9}{2x}]^5[/tex]
Divide by 2x (divide coefficient by 2, subtract coefficient degrees)
[tex][4x^8]^5[/tex]
Multiply exponents and raise 4 to the power of 5
[tex]1024x^{40}[/tex]
The reason you multiply exponents is because you can think about it like this:
(4 * x * x * x * x * x * x * x * x) (this has one 4 and 8 x's because x is raised to the power of 8. Now if you do that 5 times which is what the exponent is doing you're going to have 40 x's and 8 4's. So it's essentially
(4 * x * x * x * x * x * x * x * x) * (4 * x * x * x * x * x * x * x * x) * (4 * x * x * x * x * x * x * x * x) * (4 * x * x * x * x * x * x * x * x) * (4 * x * x * x * x * x * x * x * x). If you group like terms you'll get (4 * 4 * 4 * 4 * 4) * (x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x). Which simplifies to 4^5 * x ^ (8 * 5) which further simplifies to the answer 1024x^40
Answer:
1024x^40
Step-by-step explanation:
Apply exponent rule: (a/b)^c = a^c / b^c = (5x^9 + 3x^9)^5 / (2x)^5
Simplify:
(5x^9 + 3x^9)^5: 32768x^45
= 32768x^45 / (2x)^5
Simplify:
(2x)^5: 32x^5
= 32768x^45 / 32x^5
Divide the numbers: 32768 / 32 = 1024
= 1024x^45 / x^5
Apply exponent rule: x^a / x^b = x^a - b
x^45 / x^5 = x^45 - 5
= 1024x^45 - 5
Subtract the numbers: 45 - 5 = 40

What is the slope of the following linear equation y + 2x = 5 ?
Answer:
slope = -2
Step-by-step explanation:
The general structure of an equation in slope-intercept form is:
y = mx + b
In this form, "m" represents the slope and "b" represents the y-intercept. Since the given equation is not in the exact slope-intercept form, we need to rearrange it to identify the slope.
y + 2x = 5 <----- Given equation
y = -2x + 5 <----- Subtract 2x from both sides
Now, we can see that in the "m" position, there is a value of -2. This makes the slope = -2.
