Add (16n2 + n + 1) + (4n2 - 5n - 2).
Answer:
20n2-4n-1
Step-by-step explanation:
You combine like terms, so you add 16n2 with 4n2 to get 20n2. Then you add n with -5n to get -4n. Finally, you add 1 with -2 to get -1.

How to divide 7 divided by 7/4
Answer:
4
Step-by-step explanation:
7÷7/4
in these cases we multiply by the reciprocal
7× 4/7
7 and 7 can be cancelled with each other
the remaing answer = 4
Answer:
1/4
Step-by-step explanation:
First, since the numerator is 7 you want to see how many times you can divide that.
So, you can only divide 7 by 7 1 time so that turns into 1.
Hence, your numerator is now 1 and denominator stays the same so its..
1/4

Solve the triangle with the law of sines
Answer:
see below
Step-by-step explanation:
We can use the law of sines
sin 80 sin B
--------------- = -------------
31 14
Using cross products
14 sin 80 = 31 sin B
14/31 sin 80 = sin B
.984807753 = sin B
Taking the inverse sin of each side
sin ^ -1 ( .444751888) = B
26.41 = B
The sum of the angles of a triangle is 180
A+B+C = 180
80 + 26.41 + C =180
106.41 + C = 180
C = 73.59
We can use the law of sines to find c
sin 80 sin 73.59
--------------- = -------------
31 c
c sin 80 = 31 sin 73.59
c = 31 sin 73.59 / sin 80
c = 30.20
AB = 30.20
Which is the correct way to express 489.65 in expanded form?
A

B
400 + 80 + 9 + 0.6 + 0.05
C 400 + 80 + 9 + 6 + 0.5
D
400 + 80 + 9 + 0.065

Which function has an inverse that is a function
Answer:
Options (1) and (3)
Step-by-step explanation:
Option (1)
f(x) = x²+ 3
We can rewrite the function in the equation form as,
y = x² + 3
By interchanging y by x,
x = y² + 3
Now we solve it for y,
y² = x - 3
y = ±√(x - 3)
So the inverse function is,
[tex]f^{-1}(x)=\pm \sqrt{x-3}[/tex]
It's a function.
Option 2
d(x) = -9
Equation form of the function is,
y = -9
Replacing y by x,
x = - 9
Therefore, inverse function will be,
x = -9
Inverse is not a function
Option 3
m(x) = -7x
Equation form of the function,
y = -7x
Interchanging y by x,
x = -7y
Now solve for x,
y = [tex]-\frac{1}{7}x[/tex]
So the inverse function will be,
[tex]m^{-1}(x)=-\frac{1}{7}x[/tex]
Inverse is a function.
Option 4
p(x) = |x|
As this function not a one to one function inverse function is not possible.
Inverse of |x| is not a function.
An oil rig has a height of 74.98 m visible above water and extends 518.16 m below the surface to the sea floor. What is the total height of the oil rig?
please help i really need help A.S.A.P :). pls help me
Answer:
591.14 m
Step-by-step explanation:
74.98 (above water level) + 518.16 (below water level) = 593.14 m (total height of the oil rig)

In a unit circle, ø= 90°. Identify the terminal point and sin Ø.
A. Terminal point: (0,1); sin ø= 1
B. Terminal point: (1,0); sin ø=0 C. Terminal point: (1, 0); sin ø=1
D. Terminal point: (0,1); sin ø=0
Answer:
Terminal point: (0, 1); sinФ = 1 ⇒ A
Step-by-step explanation:
In the unit circle, Ф is the angle between the terminal side and the positive part of the x-xis.
The terminal point on the positive part of the x-axis is (1, 0),which means Ф = 0° or 360° and cosФ = 1, sinФ = 0The terminal point on the positive part of the y-axis is (0, 1),which means Ф = 90° and cosФ = 0, sinФ = 1The terminal point on the negative part of the x-axis is (-1, 0),which means Ф = 180° and cosФ = -1, sinФ = 0The terminal point on the negative part of the y-axis is (0, -1),which means Ф = 270° and cosФ = 0, sinФ = -1In a unit circle
∵ Ф = 90°
→ By using the 2nd rule above
∴ The terminal point is (0, 1)
∴ sinФ = 1
∴ Terminal point: (0, 1); sinФ = 1

Answer:
8
Step-by-step explanation:
Apparently, you want to evaluate ...
0.1m +8 -12n
for m = 30 and n = 1/4.
Put the numbers where the corresponding variables are and do the arithmetic.
= 0.1×30 +8 -12×(1/4) = 3 + 8 -3
= 8
