Step-by-step explanation:
Solving the equation,
x(3x² + 2x + 5) = 3x³ + 5x
or, 3x³ + 2x² + 5x = 3x³ + 5x
This is false.
Corrected equation will be
x(3x² + 2x + 5) = 3x³ + 2x² + 5x

Write a report to the president of the company explaining the meaning of the solutions
Step-by-step explanation:
x is less than -10
x is greater than or equal to 25
Answer:
The negative part of the solution set is ignored, because you cannot produce a negative number of phones.
The company has at least an 80% success rate if the next 25 or more phones that are assembled work.
Because the company has already made 10 phones and 7 are not working, if the next 25 phones work, the 35th phone puts the company at its goal of 80% or more.

HELP ME ASAP WHAT IS THIS ANSWER
Answer:
These kind of problems are super difficult Anna, don't feel bad for not getting this. there is a bunch of "implied" ideas here... i'll go over them below, maybe it will seem a bit easier. if not, ask some more questions in the comments of this problem , I'll see the comments and answer your question
Step-by-step explanation:
the 1st implied idea is that there is 360 ° in a circle
next you have to know, that the angle x is also matched on the interior of the circle where the line of the angle x, first touches the circle. if that is confusing , don't worry i'll make a rough drawing to show you.
so we can know that the arc from the point where the angle x makes the tanget.. or just touches the circle to where it's other leg crosses the circle the 1st time, that's angle is equal to the arc that is left over from the total circle. see this is very "implied" nobody said.. by the way... it's 360 ° minus the other arcs.. well.. I just did.. but you had to come up with that on your own, before I said that.
x = left over arc
360 = 200 + 40 + x
120 = x

Given the points (4,-3) and (0, -1), which other point lies on the line?
A person places $1150 in an investment account earning an annual rate of 5.3%, compounded continuously. Using the formula V = Pe^{rt}V=Pe rt , where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest, determine the amount of money, to the nearest cent, in the account after 10 years.
The amount of money that would be in the investment account with continous compounding would be $12,125.94.
What is the future value of the investment account?The formula for calculating future value when there is continuous compounding is :
A x e^r x N
Where:
A= amount e = 2.7182818 N = number of years r = interest rate1150 x (e^0.053) x 10 = $12,125.94

Find the measure of the indicated angle that makes lines u and v parallel.
Please i really need help
Answer:
1. 135°
2. 114°
3. 118°
4. 81°
Step-by-step explanation:
Let "x" represent the measure of the indicated angle in each problem.
1. x = 135° (corresponding angles theorem)
2. x = 180° - 66° (same-side interior angles theorem)
x = 114°
3. x = 118° (alternate interior angles theorem)
4. x = 81° (alternate exterior angles theorem)

Answer:
x = 1
x = 0
x = 1 1/4
Step-by-step explanation:
x = 1
x = 0
x = 1 1/4
The < sign means less than. -1/4 is less than 1, 0, and 1/4, and more than -3/4 and -1. So, 1, 0, and 1 1/4 are the right answers.

How many moles are in 9.03 x 1023 Li atoms?
please help me
Answer:
1.5 moles
Step-by-step explanation:
number of moles = no. of particles / Avagadro number
therefore, number of moles. = 9.033 * 10^23 / 6.022 * 10^23
therefore, no. of moles = 1.5
There are 1.5 moles in 9.033 * 10^23 Lithium atoms.

Cara belongs to a knitting group that meets at the local craft shop. From observations, she has hypothesized that people purchase knitting
needles only if they are also purchasing yarn.
To confirm her thinking, Cara surveyed five people who came into the shop at various times throughout the day and asked them about their
past purchases.
Which of these factors is the most likely to skew the results of Cara's observations?
А. The participants are not randomized.
B. The sample size is too small to represent the population,
C. People have to buy yarn at a craft shop.
D. A control group is needed for an observational study.
Answer:
B. The sample size is too small to represent the population
Step-by-step explanation:
Logically speaking, this is correct because out of an ENTIRE day of customers entering a craft shop, more than 5 people enter the store. Due to this, Cara should've surveyed a larger number of customers.
