To find the value of angle A, we'll need to use a trigonometric function. In this case, we are given the adjacent side and the hypotenuse. So, we should use cosine. And because we are finding an angle, we will need to use the inverse cosine.
cos(a) = 3/8
a = cos^-1(3/8)
a = 67.98 degrees
Hope this helps! :)
How can you find f(2) if f(x) = -3x2 – 7?
Answer:
-3(2) x 2 -7 = -6x2-7 =-19
Step-by-step explanation:
The value of f(2) for the given function f(x) = -3x² – 7 will be -19.
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
As per the given function,
f(x) = -3x² – 7
Put x = 2
f(2) = -3(2)² - 7
f(2) = -2(4) - 7
f(2) = -8 - 7 = -15
Hence "The value of f(2) for the given function f(x) = -3x² – 7 will be -19".

.3a + .8 = .5a - 2
Answer:
14
Step-by-step explanation:
.3a+.8=.5a-2
Subtract. 3a from both sides:
.8=.2a -2
Add 2 to both sides:
2.8=.2a
Multiply both sides by 5:
a=14
Hope this helps!
Answer:
a = 14
Step-by-step explanation:
.3a + .8 = .5a - 2
.3a - .5a = -2 - .8
-.2a = -2.8
a = -2.8/-.2
a = 14

Which function has the greater slope and what does it indicate?
Answer:
The math function has the greater slope, which shows that the estimated time per question for math is greater than the estimated time per question for language arts.
OR B on edge
Step-by-step explanation:
The cauliflower function has the greater slope, which shows that the cost per pound of cauliflower is increasing at a faster rate than the cost per pound of broccoli.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
First, Slope for Broccoli
Slope = (3.6 - 3) / (3 - 2.5)
Slope = 0.6 / 0.5
Slope = 1.2
Second, Slope for Cauliflower
slope = (4.50 - 2.75) / (4.5 - 2.75)
= 1.75 / 1.75
= 1.000
Since the slope of the cauliflower function (1.0000) is greater than the slope of the broccoli function (0.8364), we can conclude that the cauliflower function has the greater slope.

Find the value of .
Answer: 25
Step-by-step explanation: In this problem, we're given a diagram and were asked to find the value of x.
Since the two lines in the figure intersect, we know that they form vertical angles and remember that vertical angles are always congruent, or of equal measure.
Therefore, since we know that one angle measures 75° and the other angles measures 3x°, we can setup the equation 75 = 3x.
To get x by itself since 3 is being multiplied by x,
divide both sides of the equation by 3.
On the left, 75 divided by 3 is 25
and on the right, the 3's cancel.
So the value of x in the diagram shown is 25.

Terrence gets a loan with a $50 processing fee. The loan is for $700 with an interest rate of 8% for one
year.
The interest on the loan is
The APR on this loan is
Answer:
15.14%
Step-by-step explanation:
The formula for APR is stated thus:
APR=fees+interest/principal/n*365*100
principal is the loan amount of $700
fees is the processing fees on the loan which is $50
interest amount=principal*interest %=$700*8%=$56
n is the number of days of the loan which is a year i.e 365 days
APR=($50+$56)/$700/365*365*100
APR=$106/$700/365*365*100
APR=0.151428571 /365*365*100
APR=0.151428571 *100=15.14%
The annual percentage rate on the loan is 15.14% which represents the actual cost on the loan not just the interest cost of 8% annually

The areas of the squares adjacent to two sides of a right triangle are 32 units^2 2 squared and 32 units^2 Find the length, xxx, of the third side of the triangle.
Answer:
8 units
Step-by-step explanation:
If the area of the squares are 32 units^2, we have that:
Area = Side * Side
Side^2 = 32
Side = sqrt(32) = 5.657 units
So as the squares are adjacent to two sides of the triangle, we have that the triangle has two sides of 5.657 units
As it is a right triangle, we can use the Pythagoras' theorem:
c^2 = a^2 + b^2
c^2 = 5.657^2 + 5.657^2
c^2 = 64
c = 8 units

what is s+53=g so g=68 so how old is sweet age add
Answer:
s = 15
Step-by-step explanation:
Using the given information to solve for s, the work would look something like this:
s + 53 =g, g=68
s + 53 = 68 (Subtract 53 from both sides to get s by itself)
53 - 53 = 0, 68 - 53 = 15
s = 15
Therefore, s is equal to 15
Hope this helps! Have a good rest of your day!
Answer:
15
Step-by-step explanation:
This is very simple, first we write the equation, s+53=g, and plug 68 into "g", so now we have s+53=68. Subtract both sides, s+53-53=68-53, and this equals 15 years of age
what is the correlation coefficient for the data in the table -0.93,-0.27,0.27.0.93
The answer to this question is the letter D.
The correlation coefficient is a statistical measure of the strength of the relationship between the relative movements of two variables. The values range between -1.0 and 1.0. A calculated number greater than 1.0 or less than -1.0 means that there was an error in the correlation measurement.
How to find the correlation coefficient for the data table -0.93,-0.27, 0.27, 0.93?
This is because the correlation coefficient focuses on the linear relationship between two variables.
