Find the difference (6x+7)/(2x) - (3)/(x^(2))
Answer:
[tex] \frac{(6x + 7)}{(2x)} - \frac{3}{ {x}^{2} } \\ = \frac{x(6x + 7) - 6}{2 {x}^{2} } \\ = \frac{ {6x}^{2} + 7x - 6}{2 {x}^{2} } \\ = 3 + \frac{7}{2x} - \frac{3}{ {x}^{2} } [/tex]

A surveyor has a survey a triangular plot of land. One side of the plot lies along countryside road. This side is 400 ft long. The second side is the gore road, which intersects countryside road at an angle of 88 degrees. The third side of this plot of land is 550 ft long. Determine the distance of the gore road that makes up in the unknown side of plot to the nearest foot
9514 1404 393
Answer:
392 ft
Step-by-step explanation:
As in the attached figure, you seem to have sides b and c of the triangle, along with angle C. You want to find side 'a'. The law of sines can be used to find angle B, then angle A can be found from the sum of angles. Knowing angle A, we can find side 'a'.
sin(B)/b = sin(C)/c
sin(B) = (b/c)sin(C) = 400/550·sin(88°)
B = arcsin(8/11·sin(88°)) ≈ 46.621°
Then angle A = ...
A = 180° - B - C = 180° -46.621° -88° = 45.379°
Now, we can find side 'a' from ...
a/sin(A) = c/sin(C)
a = c·sin(A)/sin(C) ≈ 550·sin(45.379°)/sin(88°) ≈ 391.710 . . . feet
The unknown side of the triangle is about 392 feet.
help me pls will maerk brainliest
Answer:
43.75 ft²
Step-by-step explanation:
Actual sizes
4/2 *5 = 10 feet
3.5/2 * 5 = 8.75 feet
Area
a = (1/2)bh
a = (1/2)(10)(8.75)
a = 43.75 ft²

Write the phrase as a numerical expression.
3.
5 more than 8
4. 8 less than 2 times a number
3. 8+5
4. 2x - 8
Step-by-step explanation:
3. for example : 5 more than the number means
x+5 so that's how we get the answer as 8+5
4. This can be explained in two folds firstly, for example: 2 less than the number means x-2.
secondly;7 times the number means 7x so therefore we get our final answer as 2x - 8
d(n)=6-4(n-1) Find the fifth term in the sequence
Answer:
5th term: -10
Step-by-step explanation:
To find the nth term in the sequence, you can substitute n into the equation:
d(n) = 6 - 4(n - 1)
Since we want the 5th term, we substitute 5:
d(5) = 6 - 4(5 - 1)
d(5) = 6 - 4(4)
d(5) = 6 - 16
d(5) = -10
Please help what is the perimeter of this figure
Answer:
the picture in the attached figure
let
AB=x
we know that
perimeter of the figure=10*x
perimeter=42.5 cm
so
42.5=10*x
x=42.5/10
x=4.25 cm
area of the figure=area of rectangle +area of square
area of rectangle=4.25*(4.25*3)----> 54.1875 cm²
area of square=4.25²----> 18.0625 cm²
area of the figure=54.1875+18.0625-----> 72.25 cm²
the answer is
72.25 cm²

Solve the following system of linear equation by graphing.
4x + 2y = -2
2x – 3y = 9
Grade 9 transformation graph
Answer:
1) D
2) C
3) A
4) B
Step-by-step explanation:
Ok, we need to try each function in the point x = 0 and then analyze the limit as x goes to really large values.
1) g(x) = -3^x
When x = 0, we have:
g(0) = -3^0 = -1
Then we know that the graph of this function will be either A or D.
Now, as x goes to really large values, 3^x will eventually approximate to infinity.
Then - 3^x will approximate to negative infinnity.
From that, we can conclude that the graph for this function is the one that goes to negative infinite as x increases. That is graph D.
2) h(x) = (1/3)^(-x) = 3^x
This is the exact opposite of the previous function. So we need to find the graph that is an exact reflection across the x-axis of graph D, and that one is the graph C.
then the graph if this function is C.
3) k(x) = - (1/3)^x = -1/(3^x)
When x = 0
k(0) = -(1/3)^0 = -1
We have two options with a y-intersect at y = -1 (graph A and D) and in this case, we can see that the part that grows fast is in the denominator, then as x increases, the denominator increases, and thus the function will tend to zero, then the graph of this function is graph A.
4) g(x) = 3^(-x) = 1/(3^x)
g(0) = 1/(3^0) = 1/1 = 1
And same as before, as x increases, g(x) tends to zero.
Then the remaining graph (B) is the graph of this function.
Which set of numbers does NOT represent the lengths of the sides of a triangle? (6, 18, 23) (6, 22, 17) (16, 24, 7) (22, 8, 15
Answer:
(16, 24, 7)
Step-by-step explanation:
The Triangle Inequality states that the sum of lengths of any two sides should be greater than the length of the third side.
But 16 + 7 = 23 is not greater than 24.
help please I dont understand this
Answer:
[tex]x=6[/tex]
Step-by-step explanation:
The lengths of line segments [tex]\overline{AB}[/tex] and [tex]\overline{AC}[/tex] because of the two segments and two angles marked as equal in the diagram. Because of this, the arcs [tex]\widehat{AB}[/tex] and [tex]\widehat{AC}[/tex] are equal.
Since there are 360 degrees in a circle, we can now set up the following equation:
[tex](10x-23)+(10x-23)+106=180,\\20x-46+106=180,\\20x+60=180,\\20x=120,\\x=\boxed{6}[/tex]

For a bell-shaped distribution with µ = 30, what is the most probable value for the mode?
Answer:
[tex]Mode = 30[/tex]
Step-by-step explanation:
Given
[tex]\mu = 30[/tex] --- Mean
Required
The possible value of the mode
For a bell-shaped distribution, we have:
[tex]Mean = Mode[/tex]
Rewrite as:
[tex]Mode = Mean[/tex]
This gives;
[tex]Mode = \mu[/tex]
Hence:
[tex]Mode = 30[/tex]

her bi-weekly paycheck after FICA of 7.65%, Federal withholding of 8%, and State withholding of 3% are deducted from her gross pay?
Answer:
[tex]first \ week \ = 15.10 * 38 = 573.80\\Second\ week \ = 15.10 *38 = 573.80\\\\Total \ amount \ before \ all \ deductions = 1147.60\\[/tex]
FICA deduction 7.65%
= [tex]\frac{7.65}{100} * 1147.60 = 87.79[/tex]
Federal withholding 8%
=[tex]\frac{8}{100} * 1147.60= 91.81[/tex]
State withholding 3%
=[tex]\frac{3}{100} *1147.60 = 34.43[/tex]
Amount on paycheck = 1147.60 - 87.79 - 91.81 - 34.43 = $933.57
