Answer:
The solution of this trigonometric identity is [tex]\theta = 56.310^{\circ} \pm 180\cdot i ^{\circ}[/tex], [tex]\forall \,i\in \mathbb{N}_{O}[/tex].
Step-by-step explanation:
Let [tex]7\cdot \tan \theta - 8 = 5\cdot \tan \theta -5[/tex], we proceed to simplify the expression and solve afterwards either by algebraic or by trigonometric means:
[tex]7\cdot \tan \theta -8 = 5\cdot \tan \theta -5[/tex]
[tex]2\cdot \tan \theta = 3[/tex]
[tex]\tan \theta = \frac{3}{2}[/tex]
[tex]\theta = \tan^{-1} \frac{3}{2}[/tex]
The tangent is a trigonometric function with a period of 180°. Hence, we find that the family of angles associated with such value is:
[tex]\theta = 56.310^{\circ} \pm 180\cdot i ^{\circ}[/tex], [tex]\forall \,i\in \mathbb{N}_{O}[/tex]
The path of a flying fish as it made its approach to the surface of the ocean and flew out of the water is represented by the quadratic function h(t) = -t2 + 6t - 5, where t represents the time, in seconds, and h(t) represents the fish's height and depth, in feet. Graph the function using the graphing calculator. To the nearest second, how long was the fish out of the water?
1 second
3 seconds
4 seconds
5 seconds
Answer:
4 seconds
Step-by-step explanation:
fish broke the water's surface in 1 second and went back into the water at 5 seconds
∴ it was out of the water for 4 seconds

Evaluate the expression below when n = 2.4. If needed, answer as a fraction or a decimal.
12n−8
Answer:
20.8
Step-by-step explanation:
Plug in 2.4 as n in the expression, and simplify:
12n - 8
12(2.4) - 8
28.8 - 8
= 20.8
So, the answer is 20.8
Whats the area of the rectangle?
Length: 2 1/7
width: 3 1/3
I dont need an explanation just the simplified answer
Answer:
The area of rectangle is "31 units²".
Step-by-step explanation:
The given values are:
Length of rectangle,
= [tex]\frac{21}{7}[/tex]
Width of rectangle,
= [tex]\frac{31}{3}[/tex]
As we know,
The area of rectangle is:
= [tex]Length\times width[/tex]
On substituting the values, we get
= [tex]\frac{21}{7}\times \frac{31}{3}[/tex]
= [tex]\frac{217}{7}[/tex]
= [tex]31 \ units^2[/tex]

In Frank's piggy bank, there are only quarters
and dimes. He has 37 coins, and has a total of
$5.50. How many quarters does he have?
Answer:
12 quarters
Step-by-step explanation:
number of quarters ---------x
number of dimes ------------y
therefore, x + y = 37---------------times 10 both sides --------10x + 10y = 370-------equation 1
0.25x + 0.1y = 5.5 -----times 100 both sides -------25x + 10y = 550 ------equation 2
equation 2 minus equation 1 is 25x + 10y - 10x - 10y = 550 - 370 ------ 15x = 180 -------x = 12
there are 12 quarters

Write the decimal as a percent
Answer:
3/5
Step-by-step explanation:
Answer:
66%
Step-by-step explanation:
0.6 repeating is 66%.
From decimal to percent:
To get a percent from a decimal number, move the decimal over twice to the right. In this case, 0.66 would become 66% because the decimal moved to the right twice.
From decimal to fraction to percent:
I already know that 2 divided by 3 is 0.6 repeating. 2 divided by 3 could also be written as [tex]\frac{2}{3}[/tex]. So the first step is complete, from the decimal 0.6 repeating to the fraction [tex]\frac{2}{3}[/tex]. Now from [tex]\frac{2}{3}[/tex] to a percent. If you get a 2 out of 3 ([tex]\frac{2}{3}[/tex]) you would get a 66%.

Since its a 45-45-90 triangle then the 2 legs are going to be the same.
Answer:
90°
Step-by-step explanation:
Always remember that the sum of all angles is 180°.
So there are two 45° angles, so just add them up and you get 90
So if you subtract 90 from 180, you get 90, and that's your answer
The function h(n) = 8 - 3n represents the value of the nth term in a sequence.
What is the product of the 2nd and 5th terms of the sequence?
Answer:
aaaa
Step-by-step explanation:
Answer:
h(2) = 2
h(5) = -7
Step-by-step explanation:
h(n)=8-3n
h(1)=8-3(1) = 5
h(2)=8-3(2) = 2
h(5) = 8-3(5) = 8-15 = -7
A company sells fruit smoothies in two sizes: 6 ounces and 20 ounces. You know that a 6-ounce bottle contains 96 milligrams of sodium. If the amount of sodium is directly proportional to the fluid ounces of smoothie, how many milligrams of sodium does a 20-ounce bottle contain?
And can yall put an explanation please
Answer:
320 milligrams of sodium
Step-by-step explanation:
Create a proportion where x is the milligrams of sodium a 20 ounce bottle has:
[tex]\frac{96}{6}[/tex] = [tex]\frac{x}{20}[/tex]
Cross multiply and solve for x
1920 = 6x
320 = x
So, a 20 ounce bottle will have 320 milligrams of sodium

The spinner is shown has eight congruent sides the spinner is spun 200 times. What is a reasonable prediction for the number of times the spinner will land on 2 or 3
Answer:
50 times
Step-by-step explanation:
Total number of faces = total possible outcomes = 8
Number of 2 or 3 on spinner = required outcome = 2
Probability of obtaining a 2 or 3 = required outcome / Total possible outcomes
P(2 or 3) = 2 / 8 = 1/ 4
From 200 ; prediction for the number of 2 or 3
1/4 * 200
= 50 times
