Answer:
The slope is 3.Step-by-step explanation:
You have to solve this using the slope formula in order to get the right answer.
[tex]\underline{\text{SLOPE:}}[/tex]
[tex]\Longrightarrow: \sf{\dfrac{Y_2-Y_1}{X_2-X_1} }[/tex]
y2= 14
y1= 8
x2= 4
x1= 2
Rewrite the problem.
[tex]\sf{\dfrac{14-8}{4-2}=\dfrac{6}{2}=\boxed{\sf{3}}[/tex]
Therefore, the slope is 3, which is the correct answer.I hope this helps. Let me know if you have any questions.

Rename 5/6 and 14/15 using the least common denominator.
Answer:
[tex]\frac{25}{30}~and~\frac{28}{30}[/tex]
Multiply 5 by 5 to get your first parameter.[tex]5 * 5 = 25[/tex]
Multiply 6 by 5 to get the denominator, or your second parameter.[tex]5 * 6 = 30[/tex]
For the second fraction, [tex]\frac{14}{15}[/tex], you need to multiply both parameters by 2, similar to before, but we now must use a different number, otherwise, the denominators will not be the same.[tex]14 * 2 = 28[/tex]
Now, multiply 15 by 2[tex]15 * 2 = 30[/tex]
The last step is to put these numbers you gathered into fractions. The bigger number always goes on the bottom, referred to as the denominator, while the smaller number, referred to as the numerator, always goes on the top.[tex]25~and~30 -- > \frac{25}{30}[/tex]
[tex]28~and~30-- > \frac{28}{30}[/tex]

Give an example of an equation that crosses the x-axis at x=3 and x=-8.
This is a problem on my math homework that I’ve been stuck on. Does anyone know how to help?
The *graph of a function* (and not an equation) f(x) crosses the x-axis for any value of x such that f(x) = 0. We call x a root of f(x) in that case.
The simplest function with roots at both x = 3 and x = -8 is
f(x) = (x - 3) (x + 8)
since
f(3) = (3 - 3) (3 + 8) = 0 • 11 = 0
and
f(-8) = (-8 - 3) (-8 + 8) = -11 • 0 = 0
bedmas 10+45/9-(14/2)=
Answer:
8.
Step-by-step explanation:
1. In PEMDAS, parenthesis always comes first. In this equation, 14 divided by 2 is in parenthesis. this equals 7. Now the equation looks like the following: 10+45/9-(7).
3. In this equation, there are no exponents, nor is there multiplication, so we move on to division. The only division left in this equation is 45 divided by 9, which is equal to 5. Now the equation looks like the following:
10+5-(7)
4. Next in PEMDAS comes addition, which in this case is 10 plus 5, which is equal to 15. Equation presently: 15-(7)
5. Lastly, subtraction. 15 minus 7= 8, therefore the overall answer is 8.
What is the distance between points A and B on the coordinate plane?
a ) 12
b) 10
c) 14.5
d) 100
Answer:
Step-by-step explanation:
use pythagorean theorem a^2 + b^2 = c^2
a = 6, b = 8
6^2 + 8^2 = c^2
100 = c^2
c = -10
since it cant really be negative, the distance becomes 10.

I need help but not urgent but urgent!!
Answer:
8.6 mile
Explanation:
[tex]\sf equation \ follows : \ \ \ d = 1.2116\sqrt{h}[/tex]
d represents the distance a person can see.h represents the height above the ocean.what the captain sees:
[tex]\hookrightarrow \sf d_c = 1.2116\sqrt{15}[/tex]
what the sailor sees:
[tex]\hookrightarrow \sf d_s = 1.2116\sqrt{120}[/tex]
Difference between them:
[tex]\sf \rightarrow 1.2116\sqrt{120} \ - \ 1.2116\sqrt{15}[/tex]
[tex]\sf \rightarrow 8.58[/tex]
[tex]\sf \rightarrow 8.6[/tex] (rounded to nearest tenth)
Answer:
8.6 miles (nearest tenth)
Step-by-step explanation:
[tex]d=1.2116\sqrt{h}[/tex]
where:
d = approximate distance a person can see (in miles)h = person's height above the ocean (in feet)Captain
Given the Captain is 15 ft above the ocean:
[tex]\implies h = 15[/tex]
Substituting this into the equation:
[tex]\implies d_1=1.2116\sqrt{15}[/tex]
Lookout
Given the lookout is 120ft above the ocean:
[tex]\implies h = 120[/tex]
Substituting this into the equation:
[tex]\implies d_2=1.2116\sqrt{120}[/tex]
Solution
To find how much farther the lookout can see than the captain, subtract the distance the captain can see from the distance the lookout can see:
[tex]\implies d_2-d_1[/tex]
[tex]\implies 1.2116\sqrt{120}-1.2116\sqrt{15}[/tex]
[tex]\implies 1.2116(\sqrt{120}-\sqrt{15})[/tex]

and 15 points
Answer: x=20
Step-by-step explanation:
The two angles provided are vertical angles.
Vertical angles are equal in measurement.
This means we can set (3x+50) and (6x-10) equal to each other and solve for x
[tex]3x+50=6x-10[/tex]
Add 10 to both sides
[tex]3x+50=6x-10\\3x+50+10=6x-10+10\\3x+60=6x[/tex]
Subtract 3x from both sides
[tex]3x-3x+60=6x-3x\\60=3x[/tex]
Divide both sides by 3
[tex]\frac{60}{3} =\frac{3x}{3} \\20=x[/tex]
Answer:
Step-by-step explanation:
(3x + 50)° = (6x - 10)°
3x - 6x = -50 - 10
3x = -60
[tex]\frac{-3x}{-3}[/tex] = [tex]\frac{-60}{3}[/tex]
x=20°

$1,700 is deposited in an account that pays 6.5% annual interest, compounded annually. What is the balance after 3 years?
Answer: $2053.51
Step-by-step explanation:
The formula for compound interest is [tex]A=P(1+\frac{r}{n} )^{nt}[/tex]
Where
A = final amount
P = initial principal balance (1700 for this)
r = interest rate (0.065 for this)
n = number of times interest applied per time period (1 for this)
t = number of time periods elapsed (3 for this)
[tex]A=1700(1+\frac{0.065}{1})^{(3)(1)} \\A=1700(1.065})^{3} \\A=2053.51435[/tex]
Rounded that is 2053.51

The main sail of a sailboat has the dimensions shown in the figure at the right. What is the height of the main sail?
Answer:
[tex]h = 16.1[/tex]
Step-by-step explanation:
[tex]sin A /a = sin B / b = sin C/c[/tex] where A is angle and a is side opposite of angle
[tex]sin (49) / h = sin(41)/ 14[/tex] cross-multiply
[tex]h*sin(41) = 14 * sin(49)[/tex]
[tex]h = (14*sin(49))/ sin(41)[/tex]

StartFraction x Over x squared + 3 x + 2 EndFraction minus StartFraction 1 Over (x + 2) (x + 1) EndFraction
Answer:
see image
Step-by-step explanation:
You are subtracting fractions. To do this you must have a common denominator. Then subtract the numerators.
In your question, the denominators (expressions on the bottom) are ALREADY THE SAME, because (x+2)(x+1) is the same as x^2+3x+2.
So to subtract, keep the denominator and subtract the tops:
x - 1
The result can be written in either factored form or standard form. The answers are equivalent. See image.

Suppose a person is standing on the top of a building and that she has an instrument that allows her to
measure angles of depression. There are two points that are 100 feet apart and lie on a straight line that is
perpendicular to the base of the building. Now suppose that she measures the angle of depression from the
top of the building to the closest point to be 33.5º and the angle of depression from the top of the
building to the furthest point to be 28.3º. Determine the height of the building. (Round your answer to the
nearest tenth of a foot.)
The building and the person on it are illustrations of elevation and depression
The height of the building is 76.9 feet
How to determine the height of the building?To calculate the building height, we make use of the attached illustration
Considering the triangle DCB in the figure, we have:
tan(B) = DC/BD
Substitute known values
tan(28.3) = DC/(DA + 100)
Cross multiply
(DA + 100) * tan(28.3) = DC
Divide both sides by tan(28.3)
DA + 100 = DC/tan(28.3)
Subtract 100 from both sides
DA = -100 + DC/tan(28.3)
Considering the triangle DCA in the figure, we have:
tan(A) = DC/DA
Substitute known values
tan(33.5) = DC/DA
Make DA the subject
DA = DC/tan(33.5)
Substitute DA = DC/tan(33.5) in DA = -100 + DC/tan(28.3)
DC/tan(33.5) = -100 + DC/tan(28.3)
Evaluate the tangent ratios
0.56DC = -100 + 1.86DC
Collect like terms
-1.86DC + 0.56DC = -100
Evaluate
-1.3DC = -100
Divide both sides by -1.3
DC = 76.9 feet
Hence, the height of the building is 76.9 feet
