Rewrite 2 cos 75° sin 75° using a double-angle identity.
Answer:
sin(150) or 1/2
Step-by-step explanation:
Using the double angle identity of sin2x = 2sinxcosx, you can determine the value of x and rewrite the function; 2sin(75)cos(75) = sin(2(75)) = sin(150) = 1/2
Please help
Much appreciated
Answer: First one, 25x^2y^22
Step-by-step explanation:
if you multiply y^5*2 you get y^10 and x^2
that makes x^2y^10
then, if you multiply y^3*4 you get y^12
so you have to add the y s that makes x^2y^22

Step-by-step explanation:
just remember when a number has absolute value bars around them it basically just makes it positive.
How many meters are there in 2.5 kilometers? 2.5 km = m 2,500 250 25 20.5
Answer:
The amount of meters that are in 2.5 kilometers are 2,500.
Step-by-step explanation:
There is 1000 meters in one kilometer. Now multiply 2.5 times 1000 and you get 2,500.
Which shows the algebraic representation of the phrase and its value when n = 4.2? "twenty-eight plus the product of five and a number" 28 minus 5 n; when n = 4.2 the value is 7 28 + 5 n; when n = 4.2 the value is 49 28 n minus 5; when n = 4.2 the value is 112.6 28 n + 5; when n = 4.2 the value is 122.6
Answer:
when n = 4.2 the value is 49
Step-by-step explanation:
Which shows the algebraic representation of the phrase and its value when n = 4.2?
"twenty-eight plus the product of five and a number"
Where the number = n
28 + 5n
n = 4.2
28 + 5(4.2)
28 + 21
= 49

A rectangle has a width of x yards and a length that is 6 more than the width. The perimeter is 20. What is the width of the rectangle? WRITE THE NUMBER ANSWER ONLY*
Answer:
it is 2 my friend
Step-by-step explanation:
if u draw a diagram you will see how u can solve with x on each side of the rectangle and 6 + x on the other sides that are perpendicular when combined u get 12+4x=20 since 20 is the perimeter so solve for x to get 2
There are 8 boys and 6
girls on a soccer team. The
coach will select a captain
and then select a co-
captain. What is the
probability of selecting a
boy and then a girl?
Answer:
the probability of selecting a boy and then a girl is 24 ÷ 91
Step-by-step explanation:
The computation of the probability of selecting a boy and then a girl is as follows:
The probability in the case when a boy is picked up
= 8 ÷ (8 + 6)
= 8 ÷ 14
The probability in the case when a girl is picked up
= 6 ÷ (8 + 6)
= 6 ÷ 14
Now the final probability is
= 8 ÷ 14 × 6 ÷ 13 ( without replacement)
= 24 ÷ 91
hence, the probability of selecting a boy and then a girl is 24 ÷ 91

Step-by-step explanation:
Congruent Triangles:
ABC and CBD are congruent triangles because:
* They have one right angle.
* They share one side
* They have one congruent angle (BD is the bisector of triangle ABC)
This implies that sides AD and DC have the same length, thus:
3y + 6 = 5y - 18
Subtracting 6:
3y = 5y - 18 - 6
Subtracting 5y:
3y - 5y = - 18 - 6
Simplifying:
-2y = -24
Dividing by -2:
y = -24 / (-2)
y = 12

The height of △XYZ is the distance from point Yto XZ←→. Find the area of the triangle. Round your answer to the nearest tenth, if necessary.
Answer:
10
Step-by-step explanation:
A triangle is a polygon shape with three sides. There are different types of triangles such as scalene, obtuse, equilateral, isosceles etc.
The area of a triangle is given by:
Area = (1/2) * base * height
For triangle XYZ, the base = |XZ| and the height = |AY|
We can calculate the base and height using the formula for the distance between two points [tex]A(x_1,y_1)\ and\ B(x_2,y_2)\ on \ the\ coordinate\ plane[/tex]
[tex]|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Therefore:
[tex]Base=|XZ|=\sqrt{(0-(-2))^2+(2-6)^2} =\sqrt{20} \\\\Height=|AY|=\sqrt{(3-(-1))^2+(6-4)^2}=\sqrt{20}[/tex]
Area = (1/2) * base * height = (1/2) * √20 * √20 = 10.

A car lot owner is trying to get rid of this year's inventory to make room for the new vehicles. He paid $25,599 for a red truck. If he sells it to a customer for $22,000, what mark down percentage did he use?
Answer:
14%Step-by-step explanation:
Step one
given data
Cost price of vehicle= $25,599
Selling price of vehicle= $22,000
Required
The percentage discount in the price
Step two:
% discount= cost price-selling price/cost price*100
% discount= 25,599-22,000/25,599*100
% discount= 3599/25,599*100
% discount= 0.140*100
% discount= 14%
The mark down percentage use is 14%

i need help i’m not good at math
Answer:
c
Step-by-step explanation:
to write in scientific notation, the number has to be less than 10 but more than one
so for the given number let’s say there’s a decimal at the end
49,010,000.
to move the decimal to the right of 4, we’re moving 7 places
that’s why once the number is
4.901
we write a x10^7 after because you have to move the decimal 7 places to the right to get it back to the original number
Luke is going to a carnival that has games and rides. Each game costs $3.50 and each ride costs $4.50. How much would Luke have to pay if he wanted to play 8 games and go on 10 rides? How much would Luke have to pay if he wanted to play x x games and go on y y rides?
Answer:
28$ games and 45$ for rides so 73$
Step-by-step explanation:
Answer:
he would pay $73.40 for 8 games and 10 rides
Step-by-step explanation:
multiply 3.50 by 8 since it costs him 3.50 per each ride. when calculated u get 28.40.then when calculated multiply 4.50 by ten since that is how much each ride costs. the total should be 45.00. now add 28.40 to 45.00 to get ur answer

Drag the tiles to the boxes to form correct pairs. (please help)
Match the pairs of equivalent expressions.
Answer:
Step-by-step explanation:
1). [tex](4t-\frac{8}{5})-(3-\frac{4}{3}t)=(4t+\frac{4}{3}t)+(-\frac{8}{5}-3)[/tex]
[tex]=(\frac{12}{3}t+\frac{4}{3}t)-(\frac{8}{5}+\frac{15}{5})[/tex]
[tex]=\frac{16}{3}t-\frac{23}{5}[/tex]
2). 7t - 22
3). 5(2t + 1) + (-7t + 28) = 10t + 5 - 7t + 28
= (10t - 7t) + 33
= 3t + 33
4). [tex]\frac{16}{3}t-\frac{23}{5}[/tex]
5). [tex](-\frac{9}{2}t+3)+(\frac{7}{4}t+33)=(-\frac{9}{2}t+\frac{7}{4}t)+(3+33)[/tex]
[tex]=(-\frac{18}{4}t+\frac{7}{4}t)+36[/tex]
[tex]=(\frac{-18+7}{4})t+36[/tex]
[tex]=-\frac{11}{4}t+36[/tex]
6). [tex]-\frac{11}{4}t+36[/tex]
7). 3(3t - 4) - (2t + 10) = 9t - 12 - 2t - 10
= (9t - 2t) - ( 12 + 10)
= 7t - 22
8). 3t + 33
Therefore, equivalent expressions are,
a). [tex](4t-\frac{8}{5})-(3-\frac{4}{3}t)=\frac{16}{3}t-\frac{23}{5}[/tex]
b). 7t - 22 = 3(3t - 4) - (2t + 10)
c). [tex](-\frac{9}{2}t+3)+(\frac{7}{4}t+33)=-\frac{11}{4}t+36[/tex]
d). 5(2t + 1) + (-7t + 28) = 3t + 33
