Answer:

$A= 53$

Step-by-step explanation:

Given

$BC = 9,6$

$AC = 7.2$

Required: Angle A

This is calculated using:

$tan\ A = \frac{Opposite}{Hypotenuse}$

From the attachment;

$Opposite = 9.6$

$Adjacent = 7.2$

So:

$tan A =\frac{9.6}{7.2}$

$tan A =1.333$

Take arctan of both sides

$A= tan^{-1}(1.333$

$A= 53$ ----- approximated

Y = one-fourth x minus 6 be determined? Explain.

Luden [163]

Answer:

Step-by-step explanation:

For a given function f(x), we define the domain as the set of the possible inputs of the function and the range as the set of the outputs of the function.

We will see that both domain and range are the set of all real numbers.

D = (-∞, ∞)

R = (-∞, ∞)

Here we have the function:

The first thing we need to do is find the domain.

We start by assuming that the domain is the set of all real numbers and then we try to find some given values of x that cause some undefined operation, and then we remove these values of x from the domain.

Where this would be something like a zero in the denominator or something like that. We also could have specific restrictions to the domain that are applied in some specific cases (for example if x represents a length we should remove the negative values from the domain).

Here we can see that we do not have any indetermination, thus the domain is the set of all real numbers.

Now to study the range we need to see the general function, we can see that as x tends to negative infinity y will also tend to negative infinity, while when x tends to infinity y will also tend to infinity.

Then the range will also be the set of all real numbers.

How to solve 11(K-1)=7(K-Y)

forsale [732]

If you're solving for y it would be

11(k-1)=7(k-y)

1) divide both sides by 7

11(k-1)
____ = k-y
7

2) then subtract k on both sides

11(k-1)
____ -k = y
7

I need help answering these questions. I have been having some trouble in math lately, It just has not seemed to be interesting

wolverine [178]

1)
A)
f(x) has a slope of +5 (change with each x step), g(x) of +2 (m of y=mx+b), so f(x) rises 2.5 times faster than g(x)
B)
y intercepts are at x=0
f(x) has its intercept at -10
for g(x) it is the b value of y=mx+b, so 8
so the g(x) intercept is greater/above the one of f(x)

2)
A)
y intercept is at x=0 -> 12

When we started measuring the bird was already 12 miles away from its nest.
B)
average rate=(f(3)-f(1))/(3-1)
=16/2=8 [mph]
The bird moved on average with a speed of 8mph away from the nest.
C)
f(x)=8x+12

insert the 172 miles distance:
172=8x+12
160=8x
20=x

so after 20 hours it would be at a distance of 172 miles
this means we know the value from x=0 to 20 so its domain is/it is defined for x values of [0,20]

3)
A)
f(2)=225
f(5)=480

calculate slope m:
m=(f(5)-f(2))/(5-2)=(480-225)/3=255/3=85$/day

b=f(0)=f(2)-2*m=225-2*85=55
y=85x+55
B)
f(x)=85x+55

C)
Your x label is the amount of days rented, the y label the total cost/rent to pay, because y has larger values decide on some scale and the range of x values you want to draw, which should be x>=0.

Draw the points which were given, (2,225) and (5,480) and draw a line through them from one end of the diagram to the other.

If a line goes through the following two points: (0,0) and (2,1), the slope of the line is:

luda_lava [24]

Answer: m = 1/2

Step-by-step explanation: Let's use the graphing method.

To find the slope of the line using the graphing method,

we first set up a coordinate system.

Next, we plot our two points, (0, 0), which we label point A, and (2, 1),

which we label point B, and we graph our line, as shown below.

Now just graph the line through the two points.

Now, remember that the slope, or m, is equal to the

rise over run from point A to point B.

To get from point A to point B, we rise 1 unit and run 2 units.

So our slope, or rise over run, is 1/2.
