Answer:
Option B, There are no real solutions
Step-by-step explanation:
Step 1: Square root both sides
[tex]x^2 = -49[/tex]
[tex]\sqrt{x^2} = \sqrt{-49}[/tex]
Since we are trying to square root a negative it would cause imaginary solutions so in conclusion we have no real solutions.

Answer:
[tex]\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}[/tex]
Topic - Arithmetic Progression ( AP )Given - a general term for a sequence.To find - the 150th term of the given sequenceso let's start ~
General term , [tex] A_{n} [/tex] = 3n + 10
let's consider certain values of n to get some information with us which will help us solve the problem further !
let's first consider , n = 1 ! then ,
[tex]3n + 10 = 3(1) + 10 \\ \dashrightarrow \: 13[/tex]
now , let's consider n = 2
[tex]3n + 10 = 3(2) + 10 = 6 + 10 \\ \dashrightarrow \: 16[/tex]
then , let's consider n = 3
[tex]3n + 10 = 3(3) + 10 = 9 + 10 \\ \dashrightarrow \: 19[/tex]
hence ,
now we've with us an AP which is as follows -
[tex]13 \: , \: 16 \: , \: 19 \: ......[/tex]
from this Arithmetic Progression ,
we can know that
a = first term = 13
d = common difference = 16 - 13 = 19 - 16 = 3
now ,
[tex]A _{n} = a + (n - 1)d \\ \implies \: A _{150} = 13 + (149)(3) \\ \implies \: A _{150} = 13 + 447 \\ \pink{\implies \: A _{150} = 460}[/tex]

Given that cos(theta) = 8/17 and that theta lies in Quadrant IV, what is the exact value of sin 2(theta)?
Answer: [tex]-\frac{240}{289}[/tex]
=========================================================
Explanation:
Use the pythagorean trig identity [tex]\sin^2(\theta)+\cos^2(\theta) = 1[/tex] and plug in the fact that [tex]\cos(\theta) = \frac{8}{17}\\\\[/tex]
Isolating sine leads to [tex]\sin(\theta) = -\frac{15}{17}\\\\[/tex]. I'm skipping the steps here, but let me know if you need to see them.
The result is negative because we're in quadrant 4, when y < 0 so it's when sine is negative.
Therefore,
[tex]\sin(2\theta) = 2\sin(\theta)\cos(\theta)\\\\\sin(2\theta) = 2*\left(-\frac{15}{17}\right)*\left(\frac{8}{17}\right)\\\\\sin(2\theta) = -\frac{240}{289}\\\\[/tex]

comedy category were for Cat-urday Night Fever.
How many people voted for Cat-urday Night Fever as the best
comedy film shown at the festival?
The number of people who voted for Cat-urday Night Fever as the best comedy film is given by the equation A = 182 people
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of people who voted for the comedy film be = A
Now , the equation will be
The total number of people = 280 people
The percentage of people who voted for the best comedy film = 65 %
So , number of people who voted for the comedy film A = percentage of people who voted for the best comedy film x total number of people
Substituting the values in the equation , we get
Number of people who voted for the comedy film A = ( 65 / 100 ) x 280
On simplifying the equation , we get
Number of people who voted for the comedy film A = 0.65 x 280
Number of people who voted for the comedy film A = 182 people
Therefore , the value of A is 182 people
Hence , the number of people is 182 people

In your answer, give the volume of the cone rounded to the nearest tenth, and then
explain how you calculated it. (Note: type out all of your work AND type out your
explanation for FULL credit.)
Answer:
39.5 in^3
Step-by-step explanation:
lol someone had the same question
The formula for a cone is (pi)(r^2)(h/3)
Since we have to use 3.14 for pi, we plug 3.14 in for pi:
(3.14)(r^2)(h/3)
The radius is 2 and the height is 8, so we plug in those numbers:
(3.14)(2^2)(8/3)
Simplify:
(3.14)(4)(2.666...)
Multiply:
(12.56)(2.666...) -> 39.49333...
Finally, we round 39.49333... to the tenths place:
39.5

According to the question, there are 37000 plants per hectare, the total corn plan required is 475,665.75 corn plants
Determining the area of a trapezium?The trapezium is a 2 -dimensional plane shape with the area calculated as shown below:
The formula for calculating the area of a trapezoid is expressed as:
Area = 0.5(a + b)h
Given the following parameters
a = 500 ftSubstitute the given parameters
Area = 1/2 (500 + 900) * 800
Area = 1/2 (1400) * 800
Area = 560000 square feet
Since 1 acre is equivalent to 43560 square feet, hence the total acre required is expressed as:
Total acre = 560000/43560
Total acre = 12.856 acres
Also since there are 37000 plants per hectare, the total corn plan required is 475,665.75 corn plants

For each value of y, determine whether it is a solution to -2y+75-5.
Is it a solution?
Answer:
• No
• Yes
• Yes
• No
Step-by-step explanation:
To determine if the 4 given values of y are solutions to the inequality, start by solving the inequality. Solving an inequality is just like that of an equation, except that the direction of the sign changes when the inequality is divided by a negative number.
-2y +7≤ -5
Subtract 7 on both sides:
-2y≤ -5 -7
-2y≤ -12
Divide by -2 on both sides:
y≥ 6
This means that the solution can be 6 or greater than 6.
-10 and 3 are smaller than 6 and are not a solutions, while 7 and 6 satisfies the inequality and are therefore solutions.
_______
Alternatively, we can also substitute each value of y into the inequality and check if the value is less than or equal to -5.
Here's an example to check if -10 is a solution.
-2y +7≤ -5
When y= -10,
-2y +7
= -2(-10) +7
= 20 +7
= 27
Since 27 is greater than 5, it is not a solution to the inequality.

Adult tickets
Child tickets Total tickets
4

32
Answer:
Total amount of tickets is 48
Step-by-step explanation:
Step 1: Determine the amount of tickets they solid in all
We see that the movie theater has a ratio of 4 adult tickets for every children ticket which means that wen a child purchases a ticket there are 2 adult tickets that come along.
32 adult tickets / (2 adult tickets per child)
16 children tickets
Total tickets: 32 adult tickets + 16 children tickets = 48 tickets
Answer: Total amount of tickets is 48

Find the slope-intercept equation
Please help me
Answer:
[tex]y = -\frac{1}{3}x + 5[/tex]
Step-by-step explanation:
To being, slope intercept form is the infamous y = mx + b form. In which, m is equal to the slope and b is equal to the y-intercept. (1) To solve this, begin by finding two points of the line. One easy point to find is when x = 0 as it intersects with the y-axis. Two points are: (0,5) and (-3,6). (2) Next, use the slope formula to solve for the slope. The slope formula is [tex]\frac{y2-y1}{x2-x1}[/tex]. Plug in the y and x values; [tex]\frac{6-5}{-3-0}[/tex]. Simpliify the fraction; [tex]\frac{1}{-3}[/tex] --> [tex]-\frac{1}{3}[/tex]. Therefore -1/3 is our slope. (3) To solve for b, the y-intercept, set up the slope-intercept equation with the newfound slope (y = -1/3x + b) and plug in a point for the y and x values. Doing this will isolate the b so you can solve for it.
6 = -1/3(-3) + b
6 = 1 + b
-1 -1
5 = b
Therefore the y-intercept (b) is 5. (4) The final step is to combine the information into the slope-intercept form; y = -1/3x + 5. Good luck!
