tan 45 * cos 45 + tan 30 * tan square 60
Answer:
Regroup Terms: cos 45 tan 45x + tan^2 tan 30x, 60
Answer:
[tex]\frac{1}{\sqrt{2}}+\frac{3}{\sqrt{3}}[/tex] , by the way, the simplified is [tex]2.439157589[/tex]
Step-by-step explanation:
I included a chart so next time you don't need to worry
tan( 45 degrees) = 1cos( 45 degrees) = [tex]\frac{1}{\sqrt{2}}[/tex] tan( 30 degrees) = [tex]\frac{1}{\sqrt{3}}[/tex] tan squared (60 degrees) is the same as saying square the answer of tan (60 degrees). So tan( 60 degrees) = [tex]\sqrt{3}[/tex] , so squareBased on the spinner shown, what is the probability of the next spin landing on an even
number?
Answer:
The probability is about 60%
Answer:
60%
Step-by-step explanation:
even numbers =6
spinner=10
6/10=3/5
3/5 x 100
=60%

p = mv Which equation shows the formula correctly solved for v? O A. V=p-m B. v=pm O C. v= m р O D. V ora
Answer:
v=p/m
Step-by-step explanation:
Divide poth side by m
So the answer will be v=p/m
-c+1 > 2 now this one
-c + 1 > 2
-c > 2-1 Move 1 to subtract.
-c > 1
c < -1 When the coefficient is negative, moving the negative to another side as changing the sign of Inequality to opposite.
Thus, the answer is c < -1

x=Cm
Answer:
x = 16cm
Step-by-step explanation:
[tex]C^{2}[/tex] - [tex]A^{2}[/tex] = [tex]B^{2}[/tex]
[tex]20^{2}[/tex] - [tex]12^{2}[/tex] = 256

The amount of paper that the copy shop used this month was a 25% increase of the amount of paper they used last month. This month, there were 78 copies made. How many copies were made last month?
Answer:
98 copies
Step-by-step explanation:
25% of 78 is 19.5
19.5 + 78 = 97.5
Because there can't be half of a copy we round up based on the decimal. Therefore the answer would 98 copies.
Find the slope of the following graph.
yaxis
(2.2)
(1.2)
Answer:
Y = 2
Step-by-step explanation:
Use the formula below to find the slope. Plug 0 in for X to find the y intercept. In this case there is no slope. Make sure next time to use commas , instead of periods . when writing coordinates.

Answer:
55
Step-by-step explanation:
m angle A and m angle C are equal sine two of those sides are equal. You would do 3x + 40 = x +50
You subtract x, leaving it to be 2x + 40 = 50
Subtract the 40, leaving it be 2x = 10
Divide both sides by 2, which leaves x = 5
and then you would do 3(5) + 40, which is 55

need help with this algebra problem ALG 2A
Answer:
If you are trying to simplify the expression, the answer is -14x^2+8x-37
Step-by-step explanation:
First, keep removing the parentheses.
(x-1)(2-x)+(x^2+5)(x-7) -x^2(x+6)
Next, try expanding the expression.
3x - x^2 - 2+ (x^2+5)(x-7)-x^2(x+6
3x-x^2-2+x^3-7x^2+5x-35-x^2(x+6
3x-x^2-2x^3-7x^2+5x-35-x^3-6x^2
Finally, simplify the expression.
-14x^2 8x-37

Step-by-step explanation:
Which expression is equivalent to 8x - 12y + 32?
A. 16(0.5x 4y +32)
B. 16(0.5x - 0.75y + 32)
C. 16(0.5x - 0.75y + 2)
D. 16(0.5x + 4y +2)
Answer:
It's the third
16(0.5x - 0.75y +2)
Step-by-step explanation:
You just divide everything by 16
8x/16= 1/2x=0.5x
-12y/16 = -3/4x=-0.75x
32/16=2

Point-slope form
Complete the point-slope equation of the line through (-4, 8) and (4,4).
Use exact numbers.
WHOEVER ANSWERS RIGHT GETS BRAINIST
There are actually two correct answers, one of them is y-4=-0.5(x-4)
First of all, the slope-intercept that can be derived from the points (-4,8) and (4,4) is y=[tex]-\frac{x}{2} +6[/tex], with -0.5 being the slope. To bring this to point-slope form, you must signify the slope and the coordinate intersection. Since there are two coordinates, there are actually two point-slope equations.
