How do you find exact values?
Answer:
Using trigonometric identities: A trigonometric identity is a relationship between trigonometric functions that we can use to find an exact value of a trigonmetric function.Using the unit circle: The unit circle is a circle with its center at the origin and a radius of 1 unit. If we place an angle, θ, with its initial side along the positive x-axis, then the point where the angle's terminal side intersects the unit circle is (cos(θ), sin(θ)).Using reference angles: Reference angles are the smallest angle that the terminal side of an angle makes with the x-axis. As it turns out, trigonometric functions of an angle and its reference angle have the same value, except that they may have different signs.
For example, suppose we want to find the exact value of tan(405°). First, we take a look at the angle 405° on a graph with the unit circle:
in this that the reference angle of 405° is 45°. We can use the fact that tangent is positive in the first quadrant and the rule for reference angles to deduce that tan(405°) = tan(45°). Then we can use the well-known fact that tan(45°) = 1 to get that tan(405°) = 1.

how does changing the net force on an object change its acceleration????????????
Answer:
Changing the net force on an object can either impress on it even more force in the direction that it is moving, making it go faster, or if you apply more net force on the object against it, then it decreases acceleration

Abdullah and Kanna are working on the same problem.
A juice box has 20% more juice in its new packaging.
The original packaging held 12 fluid ounces. How
much juice does the new packaging hold?
Whose double number line is correct?EXPLAIN YOUR THINKING!!!!!!!
Answer:
Abdullah is correct.
Step-by-step explanation:
The bottle contained originally 12 fl oz, so 12 fl oz is 100%.
The box now contains 20% more, so now it contains 120% of 12 fl oz.
120% * 12 fl oz = 1.2 * 12 fl oz = 14.4 fl oz
Also, 20% is 1/5. Abdullah divided 12 oz into 5 equal parts, and then he added one more 1/5. He interpreted the problem correctly. The amount in the new bottle is the amount of the old bottle plus 20% of that old amount.
Kanna considers the original amount to be 80%. When he adds another 20%, he is adding 1/4 of 12 which is too much. That is why he gets an incorrect answer that is to high. He interpreted the problem incorrectly. For him, the old bottle has 20% less than the new bottle. That is incorrect.
Abdullah is correct.

How many 1/4 unit cubes does it take to fill the prism?
Answer:
Each cube with side lengths of 1/4 have a volume of (1/4)3 which means each cube's volume is 0.015625 cubic units. To find how many cubes are needed to fill the prism, divide 3 cubic units by 0.015625 cubic units. Your answer will be 192 cubes.

K is no greater then 9.
The lesson is Solving 2 step inequalities
What is the sum of k° + i°?
Answer:
we have:
k + 70° = 180°
=> k = 110°
u can see that i = 180°
=> k + i = 110° + 180° = 290°

Sonia estimates that about 1 out of every 10 people is left-handed at her school. I f there are 160 students in her school, what is a reasonable number of left-handed students at Sonia's school?
Answer:
16
Step-by-step explanation:
So turn it into a percent, 1/10 is .1 or 10% so .1 x 160 = 16
Or you can divide 160/10 = 16, either way, there would be 16 left-handed students out of 160.

A charity organization is collecting change to raise money. They have collected three times as many dimes as quarters, 11 more nickels than dimes, and 2 times as many pennies as nickels. Let x represent the number of quarters. Write an expression to represent the number of dimes. Write an expression to represent the number of nickels. Write an expression to represent the number of pennies. If they have collected a total of 4,453 coins, how many of each coin have they collected? Show your work.
Answer:
x = no. of quarters
3x = no. of dimes
3x + 11 = no. of nickels
2(3x + 11) = no. of pennies
340 quarters
1020 dimes
1031 nickels
2062 pennies
Step-by-step explanation:
x = no. of quarters
3x = no. of dimes
3x + 11 = no. of nickels
2(3x + 11) = no. of pennies
x + 3x + 3x + 11 + 2(3x + 11) = 4453
x + 3x + 3x + 11 + 6x + 22 = 4453
13x + 33 = 4453
13x = 4420
x = 340 quarters
3x = 1020 dimes
3x + 11 = 1031 nickels
2(3x + 11) = 2062 pennies
Check: 340 + 1020 + 1031 + 2062 = 4453

Mr Thompson, This is my homework! Please help.
Problem 1
ax^2+bx+c is standard form(x+p)(x+q) is factored formThere's not much to say about these. You'll just have to memorize the terms. Note with standard form that the exponents decrease as you move from left to right (2,1,0).
===============================================
Problem 2
Other names for zeros are:
A) x interceptsD) solutionsThe term "root" is also applicable here.
===============================================
Problem 3
We set each piece equal to 0 and solve for x. This is the zero product property
f(x) = (x-2)(x+4)
0 = (x-2)(x+4)
(x-2)(x+4) = 0
x-2 = 0 or x+4 = 0
x = 2 or x = -4
The two x intercepts are located at (2,0) and (-4,0)
Answer: Choice C
===============================================
Problem 4
In the last problem, we found the two roots were x = 2 and x = -4
I'll let p = 2 and q = -4.
Average the roots to get (p+q)/2 = (2+(-4))/2 = -2/2 = -1
This is the x coordinate of the vertex. So h = -1
Plug this into the function to find k, which is the y coordinate of the vertex.
k = f(h)
k = f(-1)
k = (-1-2)(-1+4)
k = (-3)(3)
k = -9
The vertex is located at (h,k) = (-1, -9)
This is another way of saying the vertex is when x = -1 and y = -9
Answer: Choice C

Answer:
A = 28.26 cm², P = 38 units, A = 20 units², C = 43.96 units
Step-by-step explanation:
1) Our area of a circle is πr². Since our r = 3 cm, we can just substitute for r.
A = πr²
A = (3.14)(3)²
A = (3.14)(9)
A = 28.26 cm², like in your work.
2) Our formula for perimeter is 2l + 2w. We substitute for l = 12 and w = 7.
P = 2l + 2w
P = 2(12) + 2(7)
P = 24 + 14
P = 38 units
3) The formula for a triangle's area is A = [tex]\frac{1}{2}[/tex]bh, so we substitute for b = 10 and h = 4.
A = [tex]\frac{1}{2}[/tex] bh
A = [tex]\frac{1}{2}[/tex] (10)(4)
A = [tex]\frac{1}{2}[/tex] (40)
A = 20 units²
4) Circumference is 2πr, and we substitute for r = 7.
C = 2πr
C = 2(3.14)(7)
C = (3.14)(14)
C = 43.96 units

Can someone help me?! The picture is below you don’t have to explain if you don’t want to!!
Answer:
(a) 3:4
(b) 3:4
(c) 9:16
Step-by-step explanation:
(a) The ratio of the sides would be 15:20 but after you simplify them (divide by 5), you'd get 3:4
(b) The ratio of the perimeter would be 60:80 because you're multiplying each side length by 4. When you simplify this again (divide by 20), however, it becomes 3:4 again
(c) To find the area, you would multiply the width times height, the ratio would be 225:400. You would get the greatest common factor which is 25 and divide it on both sides to get 9:16
