zeroStep-by-step explanation:
x= π/4
sin(4x)*cos(5x) =sin(4*π/4)*cos (5*π/4) =sin(π)*cos(5π/4)sin(π) = 0, therefore the product is also zero

Quotient of 59.4 and 8.25 show work
Answer:
in previous material it was shown that the digit sum of the product of two integers is equal to the digit sum of the product of the digit ... For instance, 66/8 = 8.25. ... For example, 35/7=5; the digit sum of the quotient is 5 and the digit sum of 35 is 8.
Missing: 59.4 | Must include: 59.4
Answer:
7.2
Step-by-step explanation:
Change the divisor 8.25 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.
We then have the equations:
5940 ÷ 825 = 7.200
and therefore:
59.4 ÷ 8.25 = 7.200
Both calculated to 3 decimal places.

Q10
∠1 = ∠5 = 180° - 144° = 36°∠2 = 56°∠3 = 180° - 56° = 124°∠4 = 144° - 56° = 88°∠5 = ∠1 = 36°Q11
∠1 = 35°∠2 = 180° - 35° = 145°∠3 = 90° - 35° = 55°∠4 = 180° - ∠5 = 180° - ∠3 = 180° - 55° = 125°∠5 = ∠3 = 55°Measure of angles for figure 1:
∠1=36∠2=56∠3=124∠4=88∠5=36Measure of angles for figure 2:
∠1=35∠2=145∠3=55∠4=125∠5=55The angle is formed by two rays at a common point of the two rays.
For given figure 1:
∠1+144=180 (Sum of angles on same side of transversal is 180°)
∠1=180-144
∠1=36
∠5+144=180(Sum of angles on a line is 180°)
∠5=180-144
∠5=36
Similarly, ∠3=180-56
∠3=124
∠4+36+56=180(Sum of all angles of a triangle is 180°)
∠4=180-36-56
∠4=88
∠2+36+88=180
∠2=56
Thus, measure of angles for figure 1 are ∠1=36, ∠2=56, ∠3=124, ∠4=88, ∠5=36.
For given, figure 2:
∠1=35(Alternate angle on same side of transversal are equal)
∠2=180-35
∠5=180-35-90(Sum of all angles of a triangle is 180°)
∠5=55
∠4+55=180(Sum of angles on a line is 180°)
∠4=180-55
∠4=125
Similarly, ∠2=180-35(Sum of angles on a line is 180°)
∠2=145
∠3=180-35-90(Sum of all angles of a triangle is 180°)
∠3=55
Thus, measure of angles for figure 2 are ∠1=35, ∠2=145, ∠3=55, ∠4=125, ∠5=55

-100 = -t/5 - 4
please find t! (Explain aswell)
Answer:
[tex]t=480[/tex]
Step-by-step explanation:
Given
[tex]-100 = -\frac{t}{5} - 4[/tex]
Required
Solve for t
[tex]-100 = -\frac{t}{5} - 4[/tex]
Add 4 to both sides
[tex]4-100 = -\frac{t}{5} - 4+4[/tex]
[tex]4-100 = -\frac{t}{5}[/tex]
[tex]-96 = -\frac{t}{5}[/tex]
Multiply both sides by -5
[tex]-5*-96 = -\frac{t}{5} *-5[/tex]
[tex]-5*-96 = t[/tex]
[tex]480 = t[/tex]
[tex]t=480[/tex]

Small baskets of tomatoes are sold at a vegetable stand for $3 per basket. Large baskets
of tomatoes are sold at the stand for $5 per basket. Only whole numbers of baskets may be
purchased.
Another customer claims that he can purchase a total of 10 baskets of tomatoes
and pay $45.
B. Use a system of equations that describes this other customer's purchase to
explain why the claim is incorrect.
hello lol srry I don't know what to do
The customer's claim is incorrect because the value of the number of baskets are in decimal.
What is a system of equation?A system of equations is a set or collection of equations that you deal with all together at once. For a system to have a unique solution, the number of equations must equal the number of unknowns.
For the given situation,
Let the number of small baskets be x
and the number of large baskets be y
Price of small basket = $3 per basket
Price of large basket = $5 per basket
Number of baskets purchased by customer = $45
The system of equations for the above statements are
[tex]x+y=10[/tex] ------ (1)
[tex]3x+5y=45[/tex] ------ (2)
From 1, [tex]x=10-y[/tex]
Now, substitute x in equation 2,
⇒ [tex]3(10-y)+5y=45[/tex]
⇒ [tex]30-3y+5y=45[/tex]
⇒ [tex]2y=45-30[/tex]
⇒ [tex]2y=15[/tex]
⇒ [tex]y=\frac{15}{2}[/tex]
⇒ [tex]y=7.5[/tex]
Substitute the value of y in equation 1, we get
⇒ [tex]x=10-7.5[/tex]
⇒ [tex]x=2.5[/tex]
Only whole numbers of baskets may be purchased. But the value of x and y are in decimals.
Hence we can conclude that the customer's claim is incorrect because the value of the number of baskets are in decimal.

Which one of the points A(5.2). B(6,-3) and C(4.7) is the mid-point of the other two? Check your answer by calculating two distances.
Answer:
A is the midpoint
Step-by-step explanation:
Given
A(5.2) B(6,-3) and C(4.7)
Required
Which is the midpoint
Midpoint is calculated using:
[tex](x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)[/tex]
Testing A as the midpoint, we have:
[tex](5,2) = \frac{1}{2}(6+4,-3+7)[/tex]
[tex](5,2) = \frac{1}{2}(10,4)[/tex]
[tex](5,2) = (\frac{1}{2}*10,\frac{1}{2}*4)[/tex]
[tex](5,2) = (5,2)[/tex]
The above equation is true. Hence, A is the midpoint of B and C

Answer:
[tex]25C_{12}[/tex]
Step-by-step explanation:
We are given that an expression
[tex]\frac{25!}{(25-12)!12!}[/tex]
We have to find the expression which represents [tex]\frac{25!}{(25-12)!12!}[/tex].
We know that
[tex]nP_r=\frac{n!}{(n-r)!}[/tex]
[tex]nC_r=\frac{n!}{(n-r)!r!}[/tex]
By using the formula
By comparing we get
n=25,r=12
[tex]\frac{25!}{(25-12)!12!}[/tex]
[tex]=25C_{12}[/tex]
Hence, option a is true.
