Answer:
d can be right answer....
4cos^2(x)-7cos(x)+3
Please help and explain how you did it :)
I assume you're asked to solve
4 cos²(x) - 7 cos(x) + 3 = 0
Factor the left side:
(4 cos(x) - 3) (cos(x) - 1) = 0
Then either
4 cos(x) - 3 = 0 or cos(x) - 1 = 0
cos(x) = 3/4 or cos(x) = 1
From the first case, we get
x = cos⁻¹(3/4) + 2nπ or x = -cos⁻¹(3/4) + 2nπ
and from the second,
x = nπ
where n is any integer.
what is π plus e its so easy

Which inequality correctly compares Three-fourths, One-seventh, and Five-sixths? One-seventh < Three-fourths < Five-sixths One-seventh < Five-sixths < Three-fourths Three-fourths < Five-sixths < One-seventh Three-fourths < One-seventh < Five-sixths
Answer:
The inequality which correctly compares Three-fourths, One-seventh, and Five-sixths is : One-seventh < Three-fourths < Five-sixths.
The first option is correct.
Step-by-step explanation:
To determine which inequality correctly compares Three-fourths, One-seventh, and Five-sixths, we will arrange them in ascending order.
To do this, first, we will determine the LCM of the fractions denominators..
Three-fourths, One-seventh, and Five-sixths
[tex]\frac{3}{4}, \frac{1}{7}, and \frac{5}{6}[/tex]
The denominators are 4, 7 and 6.
LCM of 4,7 and 6 is 84
Then, we will write the fractions in a form whereby they all have the same denominators.
[tex]\frac{3}{4}, \frac{1}{7}, and \frac{5}{6}[/tex] can be written as
[tex]\frac{63}{84}, \frac{12}{84}, and \frac{70}{84}[/tex]
The resulting order of the numerators gives the order of the fractions.
Now, we will arrange [tex]\frac{63}{84}, \frac{12}{84}, and \frac{70}{84}[/tex] in ascending order. This becomes
[tex]\frac{12}{84}, \frac{63}{84},and \frac{70}{84}[/tex].
∴ The ascending order of the fractions is [tex]\frac{1}{7}, \frac{3}{4},and \frac{5}{6}[/tex].
That is, One-seventh, Three-fourths, and Five-sixths.
Hence, we can write that
One-seventh < Three-fourths < Five-sixths.
This is the inequality which correctly compares Three-fourths, One-seventh, and Five-sixths

i just got it right
Answer:
B)3072
Step-by-step explanation:
an= 3•4^(n-1)
n here represent the term and here need from you 6th term
So: replace n with 6
a6= 3•4^(6-1)
=3x4^5=

The record low temperature in Hawaii is -0.15 times the record low temperature in Alaska. The record low temperature in Hawaii is 12°F. What is the record low temperature in Alaska?
Answer:the record low temperature in Alaska = -80°F
Step-by-step explanation:
Step 1
Let the temperature in Alaska be = x
such that the temperature in Hawaii be -0.15 times temperature in Alaska = -0.15 x.
Step 2
IF the record low temperature in Hawaii is 12°F.
Alaska = ??
We know that
Hawaii= -0.15 x temperature Alaska ( 0.15 x)
12°F=-0.15 x temperature Alaska(x)
Temperature of Alaska, x = 12°F/-0.15
= -80°F

hich correctly describes how the graph of the inequality 4x − 2y > 20 is shaded?
Answer:
First we need to express y in this inequality:
-2y > -4x + 20
-y > -2x + 10
y < 2x - 10
The line isn't solid because the "less" sign doesn't include equal in it.
Because the sign is "less than" the shaded part is Below the line.
Merging these 2 conclusion we get the answer:
below the dashed line.

On the double number line below, fill in the given values, then use multiplication or division to find the missing value.
Answer:
Kaylee earned $24.8 per minute.
Step-by-step explanation:
Basically, just divide the total wage, by hours earned.
in the blanks I assume you just put 24.8 dolars per 1 hour and then the final 446.40 for 18 hours at the end of the number line :)

To rent a building for a school dance Ava paid 120$ plus 2.50 for each student who attended if she paid a total of $325 how many students attended the dance
Answer:
82
Step-by-step explanation:
Answer:
82
Step-by-step explanation:
The first thing you do here is subtract 120 from 325
325-120=205
The next step is to divide 205 by 2.50 to find how many students attended
205/2.50=82
Therefore 82 students paid the $2.50 price to attend the dance

the relationship between the elapsed time in minutes since the stew was removed from the stove and temperature of the stew measured in c is modeled by the following function
The function y - 3 = 4(x + 2) is in point-slope form. Select the equivalent equation in slope-intercept form
All we need to do is solve for y.
[tex]y - 3 = 4(x + 2)\\\\y - 3 = 4x + 8\\\\y = 4x + 11[/tex]
The answer is A. y = 4x + 11.

I think of a number q, multiply it by 2 and add 5. I get the same answer as when I minus 2 from q. Find the value of q
Given:
A number is q, multiply it by 2 and add 5.
You get the same answer as when you minus 2 from q.
To find:
The value of q.
Solution:
The algebraic representation of the statement "a number is q, multiply it by 2 and add 5" is
Multiply q by 2 = 2q
Multiply q by 2 and then add 5 : 2q + 5
So, the first result is 2q+5.
When you minus 2 from q = q-2
So, the second result is q-2.
According to the question, both results are equal. Equate both results to get the value of q.
[tex]2q+5=q-2[/tex]
Isolate variable terms.
[tex]2q-q=-5-2[/tex]
[tex]q=-7[/tex]
Therefore, the value of q is -7.
