Answer:
A. y = cos x
Step-by-step explanation:
The function that we see graphed has the point (0,1), this means whichever trig function f(x) it represents f(0) = 1.
Now, only the cosine function has the property that cos(0) = 1, thus choice A is the correct answer.

3,000 marbles in 200 jars
Answer:
15 marbles in a jar.
Step-by-step explanation:
[tex]\frac{y}{3000} :\frac{1}{200}[/tex]
y · 200 = 3000 · 1
200y = 3000
200y ÷ 200 = 3000 ÷ 200
y = 15

5x+12-8x=-24 steps by step please
Step-by-step explanation:
=>first combine the like terms5x-8x+12=24
-3x+12=24
=>substruct 12 from 12 and 24-3x+12-12=24-12
-3x=12
=>divide -3 from both side-3x/3=12/-3
=-4Answer is x = 12 :)
Operations you're supposed to do in order to solve this equation are:
1. Combine like terms
2. Subtract 12 from both sides
3. Simplify
4. Divide both sides of the equation by the same term
5. Simplify.

What is the solution set to the equation 4x2 – 16 = 0?
Answer:
2
Step-by-step explanation:
add 16 to zero
4x2=16
Divide 4x by 2 and 16 by two
4x=8
divide 8 by 4
x=2
Answer:
x = ± 2
Step-by-step explanation:
Given
4x² - 16 = 0 ( add 16 to both sides )
4x² = 16 ( divide both sides by 4 )
x² = 4 ( take the square root of both sides )
x = ± [tex]\sqrt{4}[/tex] = ± 2
solutions are x = - 2, x = 2
Can someone please help. Please show work
Answer:
11. parallelogram, rectangle
12. parallelogram, rhombus
13. parallelogram, square
For parallelogram:
In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.
for rectangle:
A quadrilateral is a polygon in Euclidean plane geometry with four edges (sides) and four vertices (corners). Other names for quadrilateral include quadrangle (in analogy to triangle), tetragon (in analogy to pentagon and hexagon), and 4-gon (in analogy to n-gons for arbitrary values of n).
for rhombus:
In plane Euclidean geometry, a rhombus (plural rhombi or rhombuses) is a quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal in length. The rhombus is often called a diamond.
for Square:
·There are four methods that you can use to prove that a quadrilateral is a square. In the last three of these methods, you first have to prove (or be given) that the quadrilateral is a rectangle, rhombus, or both:
·If a quadrilateral has four congruent sides and four right angles, then it’s a square (reverse of the square definition).
·If two consecutive sides of a rectangle are congruent, then it’s a square (neither the reverse of the definition nor the converse of a property).
·If a rhombus contains a right angle, then it’s a square (neither the reverse of the definition nor the converse of a property).
·If a quadrilateral is both a rectangle and a rhombus, then it’s a square (neither the reverse of the definition nor the converse of a property).

A teacher has two boxes. The first box has a height of 15 in., a width of 6 in., and a length of 8 in. The second box’s dimensions are twice that of the first box. How many times larger is the surface area of the second box than the first box?
A. The surface area of the second box is 6 times larger.
B. The surface area of the second box is 4 times larger.
C. The surface area of the second box is 3 times larger.
D. The surface area of the second box is 2 times larger.
Answer:
The correct option is B: the surface area of the second box is 4 times larger.
Step-by-step explanation:
The surface area of the first box is given by:
[tex] SA_{1} = 2l_{1}h_{1} + 2w_{1}h_{1} + 2l_{1}w_{1} [/tex]
Where:
l₁: is the length = 8 in
h₁: is the height = 15 in
w₁: is the width = 6 in
[tex] SA_{1} = 2*8*15 + 2*6*15 + 2*8*6 = 516 in^{2} [/tex]
The second box's dimensions are:
l₂ = 2*8 in = 16 in
h₂ = 2*15 in = 30 in
w₂ = 2*6 in = 12 in
Hence, the surface area of the second box is:
[tex]SA_{2} = 2*2l_{1}*2h_{1} + 2*2w_{1}*2h_{1} + 2*2l_{1}*2w_{1} = 4(2l_{1}h_{1} + 2w_{1}h_{1} + 2l_{1}w_{1}) = 4*SA_{1} = 4*516 in^{2} = 2064 in^{2}[/tex]
Therefore, the correct option is B: the surface area of the second box is 4 times larger.
I hope it helps you!
whats 7 over 4 =35 over m in solving proportions NO LINKS PLZ
Hey there!
7/4 = 35/m
CROSS MULTIPLY BOTH of your NUMBERS
7(m) = 4(35)
7(m) = 7m
4(35) = 140
NEW EQUATION: 7m = 140
DIVIDE 7 to BOTH SIDES
7m/7 = 140/7
CANCEL out: 7/7 because that gives you 1
KEEP: 140/7 because that gives you the value of m
140/7 = m
Solve above and you have the answer of m
140/7 = 20
Therefore, the value of m = 20
Answer: m = 20
Good luck on your assignment and enjoy your day!

Answer:
7.85
Step-by-step explanation:
firstly convert the 45 deg into radians
which is 0.785398 rads multiply it by ten ..
using the formula s=r∅
Answer:
Correct Answer Is 7.85
Step-by-step explanation:
Since 45 degrees is 1/8th of a circle Then you would find the circumference divided by 8.
10= Radius Then Circumference= 62.83
(Divide Circumference by 8) = 7.85 (Answer)
I forgot how to get the mean, help is appreciated :) I've got the other ones though! ^^
To find the mean, add up all the numbers in the data set. After, divide by how many numbers are in the data set. Try it out with your data. If you need help with the actual answer, feel free to write in the comment box.

Answer:
x = 17

QPR = 35º
QRP = 60º
Step-by-step explanation:
2x + 1 = x + 18
Subtract x from both sides
x + 1 = 18
Subtract 1 from both sides
x = 17
QPR = 2x + 1
QPR = 2(17) + 1
QPR = 35º
-------------------------------
8y - 4 = 4y + 28
Subtract 4y from both sides
4y - 4 = 28
Add 4 to both sides
4y = 32
Divide both sides by 4
y = 8
QPR = 8y - 4
QRP = 8(8) - 4
QRP = 60º

y varies directly with x. If y = 15 when x = -18, find y when x = 1.6.
Answer:
y= -1.328
Step-by-step explanation:
15= k*-18
15=k*-18 (divide both sides by -18)
It doesn't go in evenly so you are left with a negative decimal
k= -0.83
Now find y
y= -0.83(1.6)= -1.328
