Answer:
steps below
Step-by-step explanation:
15 tan³x=5tanx .... (0,2π)
5tanx(3tan²x - 1) = 0
tanx = 0 x = π (0° is excluded)
or 3tan²x - 1 = 0
(√3 tanx + 1) (√3 tanx - 1) = 0
tanx = 1 /√3 x = π/6 (30°) or x = 5π/6 (150°)
tanx = - 1 /√3 x = 7π/6 (210°) or x = 11π/6 (330°)
What is 10 minus 1.5 i will mark branliest if you show woking out like collum method pls show IT
Answer:
[tex]17/2[/tex]
Step-by-step explanation:
I don't know what the column method is, but I can give you another method of solving.
We know that [tex]1.5=1~1/2=3/2[/tex], so we really want to find [tex]10-3/2[/tex].
We know that [tex]20[/tex] divided by [tex]2[/tex] is [tex]10[/tex], so we really want to find [tex]20/2-3/2[/tex].
We can combine fractions with like denominators, so we really want to find [tex](20-3)/2[/tex].
We know that [tex]20-3[/tex] is [tex]17[/tex], so we really want [tex]17/2[/tex]. We can't simplify [tex]17/2[/tex] anymore.
So, the answer is [tex]\boxed{17/2}[/tex] and we're done!
Resuelve (10x-8y)(6x+4)=
Answer:
60x^2 + 40x - 48xy - 32y
Step-by-step explanation:
Let's solve this using the FOIL (first, inner, outer, last) method.
(10x-8y) (6x+4)
= 10x × 6x + 10x × 4 - 8y × 6x - 8y × 4
= 60x^2 + 40x - 48xy - 32y
Answer: 60x^2 + 40x - 48xy - 32y

1. A rectangular canvas picture measures 12 inches by 28 inches. The canvas is mounted inside a frame of uniform width, increasing the total area covered by both canvas and frame to 612 square inches. Find the uniform width of the frame.
The uniform width of the frame is 16.61 inches.
Since a rectangular canvas picture measures 12 inches by 28 inches, and the canvas is mounted inside a frame of uniform width, increasing the total area covered by both canvas and frame to 612 square inches, to find the uniform width of the frame you must perform the following calculation:
√ (612 - (28 x 12)) = X √ (612 - 336) = X √276 = X 16.61 = X
Therefore, the uniform width of the frame is 16.61 inches.

This is what my previous tutor sent, that I don’t understand:
popsicles price: p = 0.75
c = cost
x = number of popsicles bought.
cost = popsicle price * number bought
c = p * x

1. Find the equation of a parabola with a focus of (0, -6) and directrix y = 6.
Max points
9514 1404 393
Answer:
(d) y = -1/24x² (b) y = 1/36x²Step-by-step explanation:
1. The point halfway between the focus and directrix is the origin. That is, the vertex of the parabola is the origin. Then its equation can be written ...
y = 1/(4p)x²
where p is the distance from the vertex (origin) to the focus. Here, that distance is -6, so 4p = -24 and the parabola's equation is ...
y = -1/24x²
__
2. Same deal. The vertex is the origin, but this time the focus is above the origin by 9 units. Then the equation is ...
y = 1/36x²
A down payment of $195 is made on a television that costs $1300. What percent of the
cost is the down payment?
Answer:
15%
Step-by-step explanation:
Add 195 to 1300, which gives you, 1495.
Use the formula for percent change: Difference = % * original price.
So what is the difference between 1495 and 1300? It’s 195.
Now we have 195 as the difference.
Do we know the original price of the TV? Yes we do. What is it? Its 1300 because the question states the TV costs $1300.
Now we have the equation 195 = % * 1300
We don’t know the percentage, right? So now we have to solve for %. To do that, you have to do 195 divided by 1300, which gives you 0.15. Lastly, you have to turn 0.15 into a percentage, to do that, multiply 0.15 by 100, and it should give you 15%.
Therefore, 15% is the down payment. Hope this helps!

Sam is moving bags of soil from a loading dock into a storeroom. The topsoil weighs 40 pounds per bag, and the mulch weighs 20 pounds per
bag. The cart Sam uses to move the bags can only carry up to 480 pounds.
Which graph represents the number of topsoil bags and mulch bags that Sam can move in a single trip?
Answer:
The answer would be the A (I included a picture to show you which one it is)
Step-by-step explanation:
Options D and E are out because it clearly says " bags can only carry up to 480 pound" and those are saying it can hold more than 480
Options B and C have a dashed line. If it has a dashed line that means that it is < or > and it is not because it says "up to" up to means it CAN hold exactly 480
So the only right answer would be Option A

A

Thirty copies of a textbook weigh a total of 75lb. What is the weight of each book?
Answer:
Each book weighs 2.5 pounds.
Step-by-step explanation:
75/2.5 is 30. Or you could also get the answer by 30* 2.5 which it would be 75. So, therefor, the answer is 2.5.
Answer:
2.5lb
Explanation:
In equation form the question is asking for x in
[tex]30(x) = 75[/tex]
Since multiplication is reversible (to be division), we can switch the equation up.
[tex]75[/tex] ÷ [tex]30 = x[/tex]
So the answer is
[tex]75[/tex] ÷ [tex]30 = 2.5[/tex]
