2x - 5 < 33 what are all the values to this inequality
Answer:
x < 19
Step-by-step explanation:
Given that,
An inequality 2x - 5 < 33.
LHS of the inequality is 2x - 5
RHS of the inequality is 33
LHS < RHS
i.e.
2x - 5 < 33
Add 5 to both sides of the inequality
2x - 5 +5 < 33+5
2x < 38
Divide both sides by 2.
x < 19
So, the value of x is less than 19.

Given sin 0 = ā, find cos 0.
✓[?
cos e
=
ө
Step-by-step explanation:
when you look at the graphic and the right-angled triangle :
sine is the length of the vertical leg (opposite of the associated angle) divided by the length of the Hypotenuse (the baseline opposite of the 90° angle), because the sine function values are defined for the norm circle with radius 1. for any larger circle (or triangle inscribed in such a larger circle), we get the basic trigonometric function values by measuring the sides and norming to a radius of 1 (dividing them by the length of the actual radius).
cosine is the horizontal leg (at the "bottom").
the same principle applies. the cosine value is the length of that leg divided by the length of the Hypotenuse.
we know from the given ratio for sine, that the length of the Hypotenuse is 6.
so, we know 2 sides of the right-angled triangle :
the vertical leg is 5, the Hypotenuse is 6.
now, we use Pythagoras to get the horizontal leg :
6² = 5² + leg²
36 = 25 + leg²
11 = leg²
leg = sqrt(11)
and so cosine of the angle is
sqrt(11)/6

∠a and ∠b are complementary angles. ∠a measures 22°.
what is the measure of ∠b?
Answer:
∠b = 68°
Step-by-step explanation:
Complementary angles are a pair of angles that, added together, equal 90°.
If ∠a = 22°, then the measure of∠b must equal 90° when added to that of ∠a.
To find the measure of ∠b, then, we can subtract ∠a from 90°.
90 - 22 = 68
The measure of ∠b, then, is 68°.

if 4200 out of 5600 person's voted in an election the percentage which did not vote was
Answer:
25%
Step-by-step explanation:
If the total number of people is 5600, then to find the number of people that did not vote you subtract 4200 from 5600.
5600-4200=1400
Then you can set up the number of people who didnt vote as equal to a percentage over 100
1400/5600=x/100
140000/5600=x
25=x

A plane flying horizontally at an altitude of 3 miles and a speed of 500 mi/h passes directly over a radar station. Find the rate at which the distance from the plane to the station is increasing when it is 4 miles away from the station. (Round your answer to the nearest whole number.)
Answer:
The rate at which the distance from the plane to the station is increasing is 331 miles per hour.
Step-by-step explanation:
We can find the rate at which the distance from the plane to the station is increasing by imaging the formation of a right triangle with the following dimensions:
a: is one side of the triangle = altitude of the plane = 3 miles
b: is the other side of the triangle = the distance traveled by the plane when it is 4 miles away from the station and an altitude of 3 miles
h: is the hypotenuse of the triangle = distance between the plane and the station = 4 miles
First, we need to find b:
[tex] a^{2} + b^{2} = h^{2} [/tex] (1)
[tex] b = \sqrt{h^{2} - a^{2}} = \sqrt{(4 mi)^{2} - (3 mi)^{2}} = \sqrt{7} miles [/tex]
Now, to find the rate we need to find the derivative of equation (1) with respect to time:
[tex]\frac{d}{dt}(a^{2}) + \frac{d}{dt}(b^{2}) = \frac{d}{dt}(h^{2})[/tex]
[tex] 2a\frac{da}{dt} + 2b\frac{db}{dt} = 2h\frac{dh}{dt} [/tex]
Since "da/dt" is constant (the altitude of the plane does not change with time), we have:
[tex] 0 + 2b\frac{db}{dt} = 2h\frac{dh}{dt} [/tex]
And knowing that the plane is moving at a speed of 500 mi/h (db/dt):
[tex]\sqrt{7} mi*500 mi/h = 4 mi*\frac{dh}{dt}[/tex]
[tex]\frac{dh}{dt} = \frac{\sqrt{7} mi*500 mi/h}{4 mi} = 331 mi/h[/tex]
Therefore, the rate at which the distance from the plane to the station is increasing is 331 miles per hour.

A new car is purchased for $26,000 and over time its value depreciates by one half
every 5 years. What is the value of the car 7 years after it was purchased, to the
nearest hundred dollars?
Answer: $203
Step-by-step explanation: We first start out with the exponential decay model which is y=a(1-r)^t, then plug in the numbers of your problem:
-y=26,000(1-0.50)^7
-y=26,000*0.50^7
-y=26,000*0.0078125
-y=203.125
Then, after rounding to the nearest hundred dollars you get your answer....
:) hope this helped a bit
The value of the car 7 years after it was purchased will be $203.
What is exponential decay?A quantity lowers gradually at first during exponential decay before rapidly declining after that. Half-life may be calculated using the exponential decay formula, which is also used to estimate population decrease.
It is given that, A brand-new car costs $26,000 to buy, and every five years, its value decreases by 50%.
We have to find the value of the car 7 years after it was purchased
The exponential decay model, y=a(1-r)t, is where we begin. The data from your problem are then entered.
y=-26,000(1-0.50)^7
y=-26,000*0.50^7
y=-26,000*0.0078125
y=-203.125 (-ve shows the value is declining)
Thus, the car will be worth $203 seven years after it was bought.

3 Terrence uses pieces of wood that are 10 inches long to
make whistles. He has a piece of wood that is 122 feet
long. How many whistles can he make?
Answer:
146 whistles
Step-by-step explanation:
First, convert 122 feet to inches, by multiplying it by 12
122(12)
= 1464
Divide this by 10 to find how many whistles he can make
1464/10
= 146.4
Since we can only have a whole number of whistles, we have to round down to 146.
So, he can make 146 whistles

Answer:
a) The golf ball reaches a height of 64 feet.
b) The golf ball will take 2 seconds to reach maximum height.
c) The golf ball will take 4 seconds to land after being hit.
d) The golf ball will be 48 feet above ground 1 and 3 seconds after being hit.
Step-by-step explanation:
a) The parabolic motion of the golf ball is described by a second order polynomial, that is, the equation of the parabola. To determine the maximum height of the golf ball, we need to transform the equation of the parabola given into vertex form:
[tex]h = -16\cdot (t^{2}-4\cdot t)[/tex]
[tex]h - 64 = -16\cdot (t^{2}-4\cdot t + 4)[/tex]
[tex]h - 64 = -16\cdot (t-2)^{2}[/tex]
From this form we can obtain relevant information of the maximum height of the golf ball, contained in the left side of the equation. On this approach, we conclude that the golf ball reaches a height of 64 feet.
b) The time taken by the golf ball is contained in the right side of the formula. That is, the golf ball will take 2 seconds to reach maximum height.
c) In this case, we need to factor the polynomial to find right times, that is:
[tex]h = 64\cdot t - 16\cdot t^{2}[/tex]
[tex]h = 16\cdot t \cdot (4 - t)[/tex]
The time taken by the golf ball to land is contained in the second binomial. In a nutshell, the golf ball will take 4 seconds to land after being hit.
d) If we know that [tex]h = 48[/tex], the time taken by the golf ball to be 48 feet above the ground is:
[tex]64\cdot t - 16\cdot t^{2} = 48[/tex]
[tex]16\cdot t^{2}-64\cdot t +48 = 0[/tex]
By Quadratic Formula, we have the following roots:
[tex]t_{1} = 3[/tex], [tex]t_{1} = 1[/tex]
The golf ball will be 48 feet above ground 1 and 3 seconds after being hit.

Elena can run 3 miles per hour.
Step-by-step explanation:
Given that:
a circular running track = 1/5 mile
On this track, Elena runs completing each of the laps in 1/15 of an hour
We are to find Elena running speed.
It implies that the distance of Elena = [tex]\dfrac{1}{5}[/tex]
Time to run each lap = [tex]\dfrac{1}{15} \ of \ an \ hour[/tex]
Speed is the amount of distance covered in a specified period of time.
Recall that the formula for calculating speed is:
[tex]Speed = \dfrac{distance}{time}[/tex]
[tex]Speed = \dfrac{\dfrac{1}{5}}{\dfrac{1}{15}}[/tex]
[tex]Speed ={\dfrac{1}{5}\times \dfrac{15}{1}[/tex]
Speed = 3miles / hour
As such, Elena can run 3 miles each hour.
