tan²Ф+sec²Ф=3
can someone solve this by finding all answers as the nearest whole degree
Recall that
tan²(x) + 1 = sec²(x)
for all x ≠ (2n + 1) 90°, where n is any integer. (That is, whenever x isn't an angle that is an odd multiple of 90°.)
Then
tan²(Φ) + sec²(Φ) = 3
tan²(Φ) + (tan²(Φ) + 1) = 3
2 tan²(Φ) + 1 = 3
2 tan²(Φ) = 2
tan²(Φ) = 1
tan(Φ) = ±√1
tan(Φ) = 1 or tan(Φ) = -1
Φ = tan⁻¹(1) + n 180° or Φ = tan⁻¹(-1) + n 180°
Φ = 45° + n 180° or Φ = -45° + n 180°
The first family of solution is the set of angles
{…, -315°, -135°, 45°, 225°, 405°, …}
and the second family is the set
{…, -405°, -225°, -45°, 135°, 315°, …}
(showing the solutions for n = -2 to n = 2)
You can condense the solution set into one family by noticing each angle is 45° plus some multiple of 90°, so that
Φ = 45° + n 90°
If you're looking for solutions in a given range, such as 0 ≤ Φ < 360°, then
Φ = 45°, 135°, 225° or 315°
If AX:XB as AB:AC, find missing length
AX = 5, CB = 4, AC =6, find AB
Answer:
AB = 15 ÷ 2
Step-by-step explanation:
The computation of the AB is shown below;
Given that
AX : XB as AB : AC
AX = 5
XB = 4
AC = 6
AB = x
Based on the above information
We can write as
5 : 4 as to x : 6
ratios can be written as fractions
5 ÷ 4 = x ÷ 6
(4)(x) = (5)(6)
4x = 30
x = 30 ÷ 4
x = 15 ÷ 2
Hence, the AB = 15 ÷ 2

Expand and simplify: 3(m + 2) + 4( 6 + m)
Answer:
Step-by-step explanation:
Multiply through the 3 of the first bracket to get 3m +12. Then multiply out the second bracket by -2 to get -8m -2.
Write it out in a line: 3m + 12 - 8m -2
Simplify: -5m +10
Divide by -5 again to simplify further: m - 2
Answer:
=7m+30
Step-by-step explanation:
Distribute:
=(3)(m)+(3)(2)+(4)(6)+(4)(m)
=3m+6+24+4m
Combine Like Terms:

Find the missing angle.
Answers:
40
70
120
110
Please help
Answer:
65 + 45 + X = 180
110 + X = 180
X = 180 - 110
X = 70°
that means the other angle in the triangle is 70°
then to find the angle on a straight line
70 + y = 180
collect like terms
y = 180 - 70
y = 110°
that means the angle with the question mark is 110°

-3a + 4 = -14
What the answer to this
Answer:
-6
Step-by-step explanation:
-3a + 4 = -14
-3a = -14 - 4
-3a = -18
a = -18 / 3
a = -6
Answer:
a = 6
Step-by-step explanation:
Step 1: Subtract 4 from both sides.
-3a + 4 - 4 = -14 - 4
+4 and -4 cancel out.
Step 2: Subtract 4 from -14 to get -18.
-3a = -18
Step 3: Divide both sides by -3.
a = -18/-3
Step 4: Divide -18 by -3 to get 6.
a = 6
Let's check our work by substituting a for 6.
-3(6) + 4 = -14
Multiply -3 by 6 to get -18.
-18 + 4 = -14
Add -18 and 4 to get -14.
-14 = -14
This is true, so a = 6.

Profit is always calculated as revenue minus expenses. If a company’s expenses were $10 million, write an equation that expresses profit, P, (in millions of dollars) in terms of revenue, R, (in millions of dollars). Then, determine the profit when revenue is $25 million.
a.
P = 10 minus R; $15 million
b.
P = R minus 10; $15 million
c.
P = R minus 10; $35 million
d.
P = 10 minus R; $35 million
Answer:

The price of an item has been reduced by 15%. The original price was $87.
Answer:
The new cost is $73.95
The discount was $13. 05
Step-by-step explanation:
Turn the % into a decimal so it would be 0.15.
Then multiply it to the total, 87 x 0.15 = 13. 05
so the discount subtracted $13.05 off of the original price.
87 - 13. 05 = 73.95
3/4 divided by 1/2
Step by step explanation
Answer:
1.5
Step-by-step explanation:
When we divide two fractions, such as 3/4 ÷ 1/2, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other.
We also simplify the answers to fraction problems whenever possible.
Answer: 3/2 or 1 and 1/2
Step-by-step explanation: Remember that dividing by a fraction
is the same thing as multiplying by the reciprocal of the fraction.
The reciprocal of a fraction is just that fraction flipped.
So 3/4 ÷ 1/2 can be rewritten as 3/4 × 2/1.
Before multiplying however, notice that we
can cross-cancel the 2 and 4 to get 1 and 2.
Finally, multiplying across the numerators and
across the denominators, we have 3/2 or 1 and 1/2.
how do you solve -5 ( -6 - 3x) + 8 = 83
Answer:
x=3
Step-by-step explanation:
-5(-6-3x)+8=83
Distribute the -5 to both terms in the parentheses by multiplication, multiply the -5 by the -6 and the -3x.
30+15x+8=83
Add like terms, add the 30 and the 8.
38+15x=83
Subtract 38 from both sides to isolate the x on the left side.
15x=45
Divide by 15 on both sides to solve for x.
x=3

What is the answer for
3days : 18hrs
Answer:
4 : 1
Step-by-step explanation:
(3 days : 18 hours) this is a ratio , where both the units must be same before simplifying.
1 day = 24 hours, 3 days = (3 × 24) hours
3 days = 72 hours
Now both the units are same, so we can easily simplify now.
72 hours : 18 hours

The frequency in this interval is equal to 825.
Given
A population is of size 5,500 observations.
When the data are represented in a relative frequency distribution, the relative frequency of a given interval is 0.15.
Frequency;The frequency is defined as the product of population size and relative frequency interval.
The following formula is used to calculate frequency in this interval is;
[tex]\rm Frequency= Population\ size\times Relative\ frequency \ interval\\\\[/tex]
Substitute all the values in the formula;
[tex]\rm Frequency= Population\ size\times Relative\ frequency \ interval\\\\Frequency= 5500\times 0.15\\\\Frequency= 55\times 15\\\\Frequency= 825[/tex]
Hence, the frequency in this interval is equal to 825.
