Step-by-step explanation:
tanB + cotB = (sinB)/(cosB) + (cosB)/(sinB)
= (sin2B + cos2B)/[(cosB)(sinB)]
= 1/[(cosB)(sinB)]
= (1/cosB)(1/sinB)
= (secB)(cscB)
A bag contains 14 blue marbles, 10 red marbles, and 6 yellow marbles.

I need to solve for x btw these are corresponding angles
Step-by-step explanation:
As we know corresponding angles are equal so
6x - 100° = 2x + 4° < being corresponding angles>
6x - 2x = 100 ° + 4°
4x = 104°
x = 104° / 4
x = 26°
Hope it will help :)❤

Step-by-step explanation:
Does anyone know how to solve this?
Answer:
The correct option is c.
Step-by-step explanation:
Given that,
u = 7i+4j and v = 2i-3j
We need to find the product of u and v. The dot product of two vectors is given by :
[tex]u{\cdot}v=(7i+4j){\cdot} (2i-3j)\\\\=(7i)(2i)+(4j)(-3j)\\\\=14-12\\\\=2[/tex]
So, the dot product of u and v is equal to 2.

Jerry built a 2 inch cube to hold his marble collection. He wants to build a cube with a volume 8 times larger. How much will each edge measure?
Answer:
4 inches
Step-by-step explanation:
Jerry built a 2 inch cube to hold his marble collection.
Volume of this cube = 2³ = 8 cubic inches
He wants to build a cube with a volume 8 times larger.
Hence: 8 × 8 in³ = 64 in³
The measurement of each edge is calculated as:
√64 in³ = 4 inches

75=(4x-25)
What is the value of x?
Answer:
x = 25
Step-by-step explanation:
75 = (4x - 25)
Since there are no numbers outside of the parentheses, we can remove them.
75 = 4x - 25
Now we can see that we can add 25 to both sides.
100 = 4x
Divide both sides by 4 to isolate x.
25 = x
Check by plugging in the value into the original equation.
75 = 4(25) - 25
75 = 100 - 25
75 = 75
Your answer is correct.
Hope this helps!

What is a point-slope equation of the line with slope -12 that goes through the point (5,3)?
Answer:
D. y - 3 = - 12 ( x - 5)
Step-by-step explanation:
Given
Slope (m) = - 12
Point = ( 5 , 3 ) = ( x1 , y1)
Now
Writing in point-slope equation we get
y - y1 = m( x - x1)
y - 3 = - 12 ( x - 5 )

Solve. 20/n+10 = 10/n+20 n = -10 n = -20 n = 30 n = -30
Answer:
20/n+10 = 10/n+20 n
multiply both side n,
n (20/n+10) = n(10/n+20 n)
20+10n = 10+20n^2
20+10n -20 = 10+20n^2 -20
10n = 20n^2 -10
10n - 10n = 20n^2 -10 -10n
0 = = 20n^2 -10 -10n
20n^2 -10 -10n = 0
n = 1 or n = -0.5

recall that the inside angles of a triangle add up to 180
Step-by-step explanation:
now add up all the angles and make it equal to 180 :)
as follows
X+58+45+85 = 180
now use algebra ... and solve for X :)
X = 180-58-45-85
my calculators tells me....
X = -8
what does that answer mean?
it's saying ... like this 58-8 is that angle.. does that help ? :)
Wyatt makes and sells rope doormats. He uses 200 feet of rope for each doormat. He wants to make 25 doormats. Which expression shows a correct way to find how many yards of rope he needs?
Answer: See explanation
Step-by-step explanation:
First and foremost, we should not that:
1 yard = 3 feet
We are informed that Wyatt uses 200 feet of rope for each doormat and that he wants to make 25 doormats.
The expression that shows a correct way to find how many yards of rope he needs will be:
= (200 × 25) / 3
= 5000/3
= 1666.67 yards

The equation y=21.2x represents Austin's earnings in dollars and cents, y,
for working x hours. Find the rate of change.
Given:
The equation is
[tex]y=21.2x[/tex]
Where, y is earnings for working in dollars and cents and x is the number of working hours.
To find:
The rate of change.
Solution:
The slope intercept form of a linear function is
[tex]y=mx+b[/tex] ...(i)
Where, m is the slope and b is the y-intercept.
We have,
[tex]y=21.2x[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]m=21.2[/tex]
Therefore, the rate of change is 21.2 dollar and cents per hour.
