If f(x) = 3x-2, find f(8) - f(5)
Answer:
9
Step-by-step explanation:
f(8)=3(8)-2=22
f(5)=3(5)-2=13
22-13=9
Answer:
f(8) - f(5) = 9
Step-by-step explanation:
So our function is:
f(x) = 3x - 2
Therefore, f(8) becomes:
f(8) = 3(8) - 2 = 24 - 2 = 22
And f(5) is:
f(5) = 3(5) - 2 = 15 - 2 = 13
Finaly, f(8) - f(5) is therefore:
22 - 13 = 9
So f(8) - f(5) = 9

Step-by-step explanation:
Trigonometric Functions
We need to recall some properties and definitions of the trigonometric functions.
[tex]\displaystyle \tan \theta=\frac{\sin\theta}{\cos\theta}[/tex]
[tex]\displaystyle \sec \theta=\frac{1}{\cos\theta}[/tex]
We need to simplify the following expression:
[tex]5\sin\theta\sec\theta[/tex]
Substituting the identity for the secant:
[tex]\displaystyle 5\sin\theta\sec\theta=5\sin\theta.\frac{1}{\cos\theta}[/tex]
Operating:
[tex]\displaystyle 5\sin\theta\sec\theta=5\frac{\sin\theta}{\cos\theta}[/tex]
Substituting the definition of the tangent:
[tex]\displaystyle 5\sin\theta\sec\theta=5\tan\theta[/tex]
Correct choice D.

Write an equation of the line that passes through the given point and has the given slope. (6, 4); slope -3/4
Answer:
y=-3/4x+17/2
Step-by-step explanation:
the equation for slope intercept form is y=mx+b, where m is the slope and b is the y intercept.
since we know the slope of the line, we can substitute it into the equation
y=-3/4x+b
we need to find b though.
since the equation will pass through the point (6,4) that means that if we plug it into the equation, it'll be a true statement; in this case, we can use it to solve for b.
substitute (6,4) into the equation
4=-3/4(6)+b
multiply
4=-9/2+b
17/2=b
the y intercept is 17/2
therefore the equation of the line is y=-3/4x+17/2
hope this helps :)

Answer:
The weight of square is 8 grams.
Step-by-step explanation:
Given that,
The weight of the circle = 2 grams
The weight of the triangle = 4 grams
We need to find the weight of the square. Let the weight of each square is w.
On LHS, 2 circles and 4 squares are there.
On RHS, 2 squares, 4 triangles and 2 circles are there.
For a balanced position,
Weight on LHS = Weight on RHS
[tex]2\times \text{weight of circle}+4\times \text{weight of squares}=2\times \text{weight of squares}+4\times \text{weight of triangles }+2\times \text{weight of circle}[/tex]2(2)+4(w) = 2(w) + 4(4) +2(2)
4 + 4w = 2w +16 +4
4w-2w = 20-4
2w = 16
w = 8
So, weight of square is 8 grams.

The graph shows the solution to y ≥ 2 and y < x inequality.
we have:
y ≤ 2
y ≥ 2
x > 2
y > 2
The graph is limited by a line; y = 2 (red line).
The part corresponds to the part in which y > 2.
The line is continuous, so 2 is also included in the interval
y ≥ 2
Then to find if it is "less than" (<) or "less than or equal to" (≤):
Since the line that limits this interval. The line is y = x, it is a dotted line, the extreme is not included.

D. 90
Answer:
(C). 54°
Step-by-step explanation:
m∠3 + m∠4 = 90°
m∠1 = m∠4 = 2x + 8
(4x - 2)° + (2x + 8)° = 90°
4x - 2 + 2x + 8 = 90
6x + 6 = 90
6x = 84
x = 14
m∠6 = m∠3 = 4(14) - 2 = 54°

Mrs. Carter puts a variety of wrapped chocolate candies into a bag. There
are 5 silver-wrapped candies, 1 purple-wrapped candy, 2 striped candies,
and 4 gold-wrapped candies. If 15 students select one candy at a time out
of the bag without looking, and replace the candy after each draw, how
many students would be expected to select a gold-wrapped candy from the
bag?
A. 4 Students
B. 5 Students
C. 15 Students
D. 60 Students
Answer:
4
there is only 4 golden wrapped candies
Answer:
B. 5 students
Step-by-step explanation:
There are 12 different candies to pick from, only 4 of which are gold. To find the chances of getting gold you divide 4 gold by the total of 12. This gives you a 1/3 chance of getting gold.
Since the chances are the same each time, you should expect 1/3 of the students to pick gold. So, divide 15 by 3(or multiply 15 by 1/3, same thing), to get 5 students.

Why did some World War I veterans demand their government bonus in 1932 instead of waiting until 1945, when it was promised to be paid?
Answer:
The Bonus Army was a group of 43,000 demonstrators – made up of 17,000 U.S. World War I veterans, together with their families and affiliated groups – who gathered in Washington, D.C. in mid-1932 to demand early cash redemption of their service certificates. Organizers called the demonstrators the "Bonus Expeditionary Force", to echo the name of World War I's American Expeditionary Forces, while the media referred to them as the "Bonus Army" or "Bonus Marchers". The demonstrators were led by Walter W. Waters, a former sergeant.

(Please dont just give the answer. I would appreciate it if you would put how to find the answer. Thanks )
Answer: x/100 = 96 - 80/80
so you multiply 80 times x and multiply 96-80 by 100 so

The sum of 2 numbers is 56 and the difference is 16 what are the numbers
Answer:
36 and 20
Step-by-step explanation:
let x = one number
let y = second number
set up system of equations:
x + y = 56
x - y = 16
add the two equations to get: 2x = 72
therefore, x = 36 and y = 20
Help me please find the slope and y-intercept
Answer:
Slope is 2.15
y-intercept is 2
Step-by-step explanation:
We need to find slope and y-intercept of the graph given.
The formula used to find slope is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
Looking at the graph, we can find 2 points
Point 1 : (0,-2)
Point (2): (2,-2.3)
Now putting values and finding slope:
We have: [tex]x_1=0, y_1=-2, x_2=2, y_2=-2.3[/tex]
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{2.3-(-2)}{2-0}\\ Slope=\frac{2.3+2}{2}\\ Slope=\frac{4.3}{2}\\Slope=2.15[/tex]
So, we get slope = 2.15
Now, finding y-intercept
y-intercept can be found if we put x =0
Looking at the graph, when x =0, y = 2
So, y-intercept is 2
Find the measure of each angle.
The measure of one interior angle of a parallelogram is 0.25 times the measure of another angle.
Answer: Two of the angles are 144° The other two angles are 36°
Step-by-step explanation: The sum of the angles of a parallelogram is 360°
There are two pairs of equal angles.
Using that information, we can create an equation
2x + 2(0.25x) = 360
2x + .5x = 360
2.5x = 360 . Divide both sides by 2.5 to find the value of x:
x = 144° Substitute 144 for x in the expression for the smaller angles
.25(144) = 36°
The measure of the angles in the parallelogram are 144 and 36 degrees.
What is a parallelogram?A parallelogram is a quadrilateral with two pairs of parallel sides. The opposite sides of a parallelogram are of equal length and the opposite angles are also equal.
Angles in a parallelograma + b + c + d = 360
Opposite angles are equal, so
2a + 2(0.25a) = 360
2a + 0.5 = 360
2.5a = 360
a = 360/ 2.5
a = 144
the other angle = 180 - 144 = 36 degrees
