Estimate the square root to the nearest (a) integer and (b) tenth.
46−−√
Using rounding concepts, it is found that the estimates of the square root of 46 are given as follows:
a) Rounded to the nearest integer, the square root of 46 is of 7.
b) Rounded to the nearest tenth, the square root of 46 is of 6.8.
How we round a number?To round a number to the nearest integer, we have to look at the tenths digit.To round a number to the nearest tenth, we have to look at the hundredths digit.If the digit we look is of 5 or greater, we round one to the rounded digit.Using a calculator, we have that the square root of 46 is of 6.78.
7 > 5, hence rounded to the nearest integer, the square root of 46 is of 7.8 > 5, hence rounded to the nearest tenth, the square root of 46 is of 6.8.More can be learned about rounding concepts at https://brainly.com/question/17248958

A new computer repair company offers house calls to their customers. They use the function f(h) = 45h + 80 to calculate the total repair bill, f(h), for h number of hours worked. A. What does 45 represent in the function? < B. What does 80 represent in the function? > C. Find h if f(h) = 215. What does this value of h mean in the context of the problem? <
The function f(h) = 45h + 80 of the computer repair is a linear function
45 represents the hourly rate80 represents the base costThe value of h means 3 hoursWhat 45 and 80 represents?A linear function is represented as:
f(h) = mh + c
Where:
m represents the rate; m = 45b represents the base cost or y-intercept; y = 80By comparison;
45 represents the hourly rate and 80 represents the base cost
How to calculate h?
We have:
f(h) = 45h + 80
When f(h) = 215, the function becomes
45h + 80 = 215
Subtract 80 from both sides
45h = 135
Divide both sides by 45
h = 3
Hence, the value of h means 3 hours

If csc a = -5square root 6 /12 and cos a >0, find cot a
The measure of cot(a) given that csc(a) = -5√6/12 is -1/4√61.5
Trigonometry identityGiven the following trigonometry function as shown below:
csc(a) = -5√6/12
Since csc(a) = 1/sin(a)
sin(a) = -12/5√6
sin(a) = -12√6/30 = -4√6/15 = opp/hyp
Determine the measure of cos(a)
adj^2 = (-4√6)^2+15^2
adj^2 = 144+225
adj = √369
cot(a) = cos(a)/sin(a)
cot(a) = √369/15 * 15/ -4√6
cot(a) = -1/4√61.5
Hence the measure of cot(a) given that csc(a) = -5√6/12 is -1/4√61.5

The graph of the line with the given slope that passes through (-3, 3) is shown in the image attached below.
What is the Equation of a Line in Slope-intercept Form?The equation in slope-intercept form of a line, is y = mx + b, where:
b = y-intercept
m = slope = change in y/change in x.
Given a line with slope = 2 and passes through (-3, 3), plug in m = 2 and (a, b) = (-3, 3) into y - b = m(x - a) to write the equation of the line
y - 3 = 2(x - (-3))
Rewrite in slope-intercept form
y - 3 = 2x + 6
y = 2x + 6 - 3
y = 2x + 3
Therefore, the graph of the line with the given slope that passes through (-3, 3) is shown in the image attached below.

Answer:
in the first one: BMC is equilateral triangle, because BM divides AC into equal sections, and because of that MC is 3.5 so it equals to BC.
Since angle BMC is 60° (because the triangle is equilateral), angle AMC will be 120°.
Since angle A + angle C should be 90°, if amgle C is 60°, then angle A will be 30.
In triangle AMB, angle ABM will be 30° (180°-120°(angle AMB) - 30°(angle BAM)).
As we calulated, angle A is 30° and angle ABM is 30° too, that means in BAM triangle AM=BM.
