The answer is -13 and -15.
PLS help!!! PLS help!!! PLS help!!!
Answer:
c. sin 8x + sin 2x
Step-by-step explanation:
1. Convert the product into sum or differences: 2 sin 5x cos 3x
Solution:
2 sin 5x cos 3x = sin (5x + 3x) + sin (5x -3x), [Since 2 sin A cos B = sin (A + B) + sin (A - B)]
= sin 8x + sin 2x

Answer:
59.5 feet
Step-by-step explanation:
Set up a proportion
Tree 1
17 feet tall
10 feet shadow
Tree 2
35 feet tall
x feet shadow
17/10= 35/x
(17)(35)= (10)(x)
595= 10x
/10 /10
59.5= x
The cast shadow of the second tree is 59.5 feet

Find three consecutive even integers such that the product of the first and second is 8 more than 38 times the third.
Answer:
40, 42 and 44
Step-by-step explanation:
Mark these even consecutive integers as (2n-2), 2n and (2n+2)
Note that since they are integers, n > 0 and 2n is always even
Writing the equation
(2n-2) * 2n = 38 * (2n+2) + 8
// divide both sides by 2
(2n-2) * n = 19 * (2n+2) + 4
[tex]2n^{2}[/tex] - 2n = 38n + 38 + 4
[tex]2n^{2}[/tex] - 2n - 38n - 38 - 4 = 0
[tex]2n^{2}[/tex] - 40n - 42 = 0
// divide both sides by 2
[tex]n^{2}[/tex] - 20n - 21 = 0
// rewrite the equation
[tex]n^{2}[/tex] + n - 21n - 21 = 0
n * (n+1) - 21n - 21 = 0
n * (n+1) - 21 * (n+1) = 0
(n+1) * (n-21) = 0
// separate the two possible cases
n + 1 = 0 and n - 21 = 0
n = -1 n = 21
Note that here n has to be an integer, so case n = -1 can't be a solution. Therefore we use n = 21
Calculating the consecutive even integers
2n - 2 = 2 * 21 - 2 = 40
2n = 2 * 21 = 42
2n + 2 = 2 * 21 + 2 = 44

Answer:
72.1110255093 cm
Step-by-step explanation:
round it if you have to
Answer:
75 cm
Step-by-step explanation:
The diagonal d divides the rectangle into 2 right triangles with d as the hypotenuse.
Using the right triangle formed on the left and using Pythagoras' identity.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
d² = 45² + 60² = 2025 + 3600 = 5625 ( take square root of both sides )
d = 75
The diagonal is 75 cm

Segment AB is being dilated with the center at the origin. The image of A, point A prime, has coordinates of (3.2, 6.4). What is the scale factor of the dilation and the coordinates of point B prime?
Step-by-step explanation:
The location of A is 3.2
The location of A' is 6.4
A represent pre image A' represent the new image.
The scale factor of A to A' is 2 since 3.2 x 2 =6.4
Since you didnt provide B coordinates, just multiply 2 by the B coordinate to find the B prime coordinate.
Answer: A.)The scale factor is 0.8 and the coordinates of point B prime are (–3.2, –4.8).

8x+3y= 70; y=2 Solve for x.
Answer:
8
Step-by-step explanation:
x is 8
[tex]8x + 3y = 70[/tex]
with given condition where y = 2.
Therefore, substitute the value of y in the equation.
[tex]8x + 3(2) = 70 \\ 8x + 6 = 70[/tex]
Solve the equation for x-term.[tex]8x = 70 - 6 \\ 8x = 64 \\ x = \frac{64}{8} \longrightarrow \frac{8}{1} \\ x = 8[/tex]
Answer Check by substituting the value of y and x in the equation.[tex]8x + 3y = 70 \\ 8(8) + 3(2) = 70 \\ 64 + 6 = 70 \\ 70 = 70[/tex]
Hence, the equation is true for x = 8 and y = 2.

The period of a pendulum is the time the pendulum takes to swing back and forth. The function L=0.81t^2 relates the length L in feet of a pendulum to the time t in seconds that it takes to swing back and forth. A convention center has a pendulum that is 50 feet long. Find the period.
Answer:
7.86seconds
Step-by-step explanation:
Given the expression used to model the length of the pendulum as
L=0.81t^2 where t is the period
IF the pendulum is 50 feet long, then L = 50 feet
Substitute
50 = 0.81t^2
t² = 50/0.81
t² = 61.7283
t = 7.86 seconds
Hence the period is 7.86seconds

The slope of the table is 2
What is slope?In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
here, we have,
to determine the slope:
From the table, we have the following points:
(x,y) = (0, 4) and (1,7)
The slope is then calculated as:
m = (y2 - y1)/(x2 - x1)
Substitute known values
m = (7 - 4)/(1 - 0)
Evaluate the differences
m = 3/1
Divide
m = 2
Hence, the slope of the table is 2

Which equation has a slope of -2 and passes through the point (1, -6)?
A. y = -23 – 4
B. Y = -22 that
c. y = –2x – 8
D. Y = -2x + 8
Answer:
C. y= -2x-8 is the answer
Answer:
y = -2x - 4
Step-by-step explanation:
y = mx + b(we substitute the "x" and "y" points into this general formula)
-6 = -2 (1) + b ( multiply "-2" by "1" and obtain the answer itself "-2")
(+ 2) -6 = -2 + b (+ 2)( then we add "2" on both side so the right side will be left with only "b". and "-6 + 2 = -4")
-4 = b( we substitute this answer in the general formula we've written )
y= -2x -4
The sum of three numbers is 212 .If the ratio of the first to the second is 13:16 and that of the second to the third is 2:3 then find the numbers.`
Given:
The sum of three numbers is 212 .
The ratio of the first to the second is 13:16 and that of the second to the third is 2:3.
To find:
The unknown numbers.
Solution:
We have,
First : Second = 13:16
Second: Third = 2:3
We need to combine these ratios, to get a single ratio for all three numbers.
Second: Third = 2×8:3×8 = 16:24
Now,
First: Second: Third = 13:16:24
Let the first, second and third numbers are 13x, 16x and 24x respectively.
[tex]13x+16x+24x=212[/tex]
[tex]53x=212[/tex]
[tex]x=\dfrac{212}{53}[/tex]
[tex]x=4[/tex]
So, the numbers are,
[tex]First=13x[/tex]
[tex]First=13(4)[/tex]
[tex]First=52[/tex]
Similarly,
[tex]Second=16x[/tex]
[tex]Second=16(4)[/tex]
[tex]Second=64[/tex]
And,
[tex]Third=24x[/tex]
[tex]Third=24(4)[/tex]
[tex]Third=96[/tex]
Therefore, the three unknown numbers are 52, 64, 96.
b) If f(2x - 3) = 4x + 5, then find f(x) and f(-2).
c) If f(x) = 7* then prove that
f(m + n + p) = f(m) . f(n) f(p)
pls solve at least 1 only if u know
f(2x-3)=4x+5
Let, 2x-3=g
x=(g+3)/2
So,f(2{g+3}/2 -3)=4(g+3)/2 + 5
f(g)=2g+11
So,f(x)=2x+11
f(-2)=7 ##
Answer:
f(2x - 3) = 4x + 5
f(2x-3)=2(2x-3)+11
f(x)=2x+11
f(-2)=2×-2+11=-4+11=7

Elizabeth has $10, $5, and $1 bills worth $101. she has five more five dollar bills than ten dollar bills and 4 times more 1 dollar bills than 10 dollar bills. How many of each kind of bills does Elizabeth have?
Let x be number of $10 dollar bills
Let y be number of $5 dollar bills
Let z be number of $1 dollar bills
From the question, we can come up with three equations (so we can find the values of x, y & z) :
10x + 5y + z = 101 y - x = 5z = 4xThe first equation comes from finding the total money Elizabeth has, which is $101.
The second equation comes from value of y (number of $5 bills) is more than value of x (number of $10 bills) by 5 dollars.
The third equation comes from the value of z (number of $1 bills) being 4 times more than the value of x (number of $10 bills).
Now, we will begin to find the value of x, y & z.
From the first equation,
10x + 5y + z = 101
Substitute the third equation (z = 4x) into z:
10x + 5y + 4x = 101
Simplify this and you get,
14x + 5y = 101
Now, we use the second equation. The second equation is y - x = 5. If we try to make y as the subject, it becomes y = 5 + x.
Now, substitute this into the value of y of the last working we did:
14x + 5(5+x) = 101
Simplify that and it becomes:
x = 4
Then, substitute this value of x into the second and third equations to find y and z.
y - x = 5
y - 4 = 5
y = 9
z = 4x
z = 4(4)
z = 16
Finally, let's check these answers by substituting them into the first equation to try and see if the total value is really $101.
10x + 5y + z = 10(4) + 5(9) + 16
10x + 5y + z = 40 + 45 + 16
10x + 5y + z = 101
Thus, our answers are correct. Elizabeth has FOUR $10 bills, NINE $5 bills and SIXTEEN $1 bills.
Answer:
Thus, our answers are correct. Elizabeth has FOUR $10 bills, NINE $5 bills and SIXTEEN $1 bills.

If ABCD is a parallelogram, find the measure of angle C
Answer:
47
Step-by-step explanation:
Angles B and D are equal.
Angles A and C are equal.
Anges in parallelogram add up to 360°
5x+38=8x-19
57=3x
x=19
B=(5×19)+38=133°
D=(8×19)-19=133°
A+C=360-133-133
A+C=94
A and C are the same so you can do 94/2=
Therefore, both angles A and C are 47 :D
The measure of angle c in the parallelogram is 47°.
What is a parallelogram?A parallelogram is a quadrilateral (has four sides and four angles) in which opposite sides are parallel and equal. Also, opposite angles are equal and the shape has equal diagonals.
∠B = ∠D (opposite angles are equal)
8x - 19 = 5x + 38
x = 19
∠B = 5(19) + 38 = 133°
∠C + ∠B = 180° (base angles of parallelogram_
∠C + 133 = 180
∠C = 47°
The measure of angle c in the parallelogram is 47°.
