Find the solution(s), if any, of the given equation using quadratic formula:
6x2 – 30x = 36
Answer:
x = 6 and x = -1.
Step-by-step explanation:
The given equation is :
[tex]6x^2-30x=36\\\\6x^2-30x-36=0\\\\or\\\\x^2-5x-6=0[/tex]
We can solve it using the middle term splitting method.
[tex]x^2-(6x-x)-6=0\\\\x^2-6x+x-6=0\\\\x(x-6)+1(x-6)=0\\\\(x-6)=0\ and\ (x+1)=0\\\\x=6\ and\ x=-1[/tex]
So, the solutions are x = 6 and x = -1.

Given the following diagram, find the trigonometric ratios.
Leave answers as reduced fractions (improper fractions are fine).
B
sinA=
COSA =
Answer:
Sin A = 3/5
Cos A = 4/5
Step-by-step explanation:
To find trigonometric ratio, recall SOHCAHTOA.
Thus:
Reference angle = <A
Opposite side to <A = 6
Adjacent side = 8
Hypotenuse = AB = √(8² + 6²) = 10 (pythagorean theorem)
Therefore,
✔️Sin A = Opp/Hyp
Sin A = 6/10 = 3/5
✔️Cos A = Adj/Hyp
Cos A = 8/10 = 4/5

An engine raises 120kg of water through a height of 40m in 30s what is the power of the engine?(g=10m/s2
Answer:
4800J/s
Step-by-step explanation:
m = 120kg
H = 40m
t = 30sec
Input energy = 120 × g × H = mgn
Ei = 120 × 40 × 30 = 144000J
Energy per sec, E1 = 144000 ÷ 30 = 4800J/s
Power input = 4800J/s

The perimeter of a rectangle is 96 feet, and the width is 22 feet. What is the length of the rectangle?
Answer:
26 feet
Step-by-step explanation:
The perimeter of a rectangle is 2 times its length and 2 times its width, or [tex]2l+2w=P[/tex]. Let's plug in the given values for the width and perimeter and solve.
[tex]2l+2(22)=96[/tex]
Simplify.
[tex]2l+44=96[/tex]
Subtract 44 on both sides.
[tex]2l+44-44=96-44[/tex]
Simplify.
[tex]2l=52[/tex]
Divide by 2 on both sides.
[tex]\frac{2l}{2} =\frac{52}{2}[/tex]
Simplify again to find the value of [tex]l[/tex].
[tex]l=26[/tex]
The length is 26 feet.

A circular flower bed is 16 m in diameter and has a circular sidewalk around it that is 3 m wide. Find the area of the sidewalk in square meters. Use 3.14 for pi
pls help me (:
Answer:
Area of sidewalk = 178.98 m²
Step-by-step explanation:
Given:
Diameter = 16 m
Length of sidewalk = 3 m
Find:
Area of sidewalk
Computation:
Radius of circle = 16 / 2 = 8 m
Radius of outer circle = 8+3 = 11 m
Area of sidewalk = π[r1² - r2²]
Area of sidewalk = π[r1² - r2²]
Area of sidewalk = 3.14[11² - 8²]
Area of sidewalk = 3.14[121 - 64]
Area of sidewalk = 3.14[57]
Area of sidewalk = 178.98 m²

Answer:
6. r = 21 cm
7. A = 155.5 m²
Step-by-step explanation:
7: Formula for arc length is;
S = (θ/360) × 2πr
We are given;
S = 51 cm
θ = 139°
Thus;
51 = (139/360) × 2π × r
Making r the subject;
r = (51 × 360)/(2π × 139)
r ≈ 21 cm
8) Area of sector is gotten from the formula;
A = (θ/360) × πr²
A = (220/360) × (π × 9²)
A = 155.5 m²
How can the mean of the values in a numerical data set be calculated?
A
Order the values in the data set from least to greatest, then find the middle value.
B. Find the sum of the values in the data set, then divide by the middle value in the set.
с
Find the sum of the values in the data set, then divide that sum by the number of values in the set
D
Order the numbers in the data set from least to greatest, then subtract the least value from the greatest value.
Answer:
C
Step-by-step explanation:
Mean is the average. To find mean, add all the numbers in a data set, then divide by the number of values.
Example: 1,2,3,4,5
Mean: 1+2+3+4+5= 15
Number of values: 5
15/5 = 3
Mean is 3
A savings account starts with $181.25. After 7 years of continuous compounding at an interest rate, r, the account has $1450.
What is the interest rate percentage?
Round the answer to the nearest hundredth.
Answer:

a and b are positive integers and a-b=2. Evaluate the following: 27^1/3^b/9^1/2^a
(a picture will be provided as well)
Answer:
Step-by-step explanation:
[tex]\frac{27^{1/3b}}{9^{1/2a}}[/tex]
We know that 27^(2/3) = 9. So:
= [tex]\frac{27^{1/3b}}{27^{1/3a}}[/tex]
note: 9^(1/2a) = 9^((2/3)(1/2)(a)) = 27^(1/3a)
[tex]= 27^{1/3b-1/3a}=27^{1/3(b-a)} = 27^{1/3(2))} = 9[/tex]
9 is the answer
Answer:
1/9Step-by-step explanation:
a - b = 2
[tex]27^{1/3b} / 9^{1/2a}[/tex] =[tex](3^3)^{1/3b} / (3^2)^{1/2a}[/tex] =[tex]3^{b} / 3^a[/tex] =[tex]3^{b - a}[/tex] =[tex]3^{-2}[/tex] = 1/9+ $13.00 shipping + 6% sales tax.

Are all isosceles triangles similar? Are all right triangle similar? Are all isosceles right triangles similar? Explain.
Please don't answer with one answer, blank or a ridiculous response. This is serious please.
And don't send links that are viruses
Please explain each one.
9514 1404 393
Answer:
a) no
b) no
c) yes
Step-by-step explanation:
a) Isosceles triangles can have a third angle (the one that is not part of the pair of equal angles) with any value in the range 0 < α < 180°. Triangles with different angle values will not be similar.
Not all isosceles triangles are similar.
__
b) The smallest acute angle of a right triangle can have any measure in the range 0 < α ≤ 45°. Right triangles having different smallest angles will not be similar. The attachment shows dissimilar right triangles.
Not all right triangles are similar.
__
c) If the smallest acute angle of a right triangle is 45°, then both acute angles are 45°, and the right triangle is an isosceles triangle. Each such triangle will be similar to every such triangle.
All isosceles right triangles are similar.

You deposit $4200 in an account that pays 7.3% annual interest compounded continuously. How much will you have after three years?
Answer:
$5228.16
Step-by-step explanation:
Given data
Principal= $4200
Rate= 7.3%
Time= 3 years
The continuous compounding formula is given as
A= Pe^rt,
where e is the mathematical constant approximated as 2.7183.
Substitute
A= 4200*2.7183^(0.073*3)
A= 4200*2.7183^(0.219)
A= 4200*1.2448
A= $5228.16
Hence the value is $5228.16

Write the slope-intercept form of the equation that goes through the point (0,0)
and is parallel to the line that has a slope of -6.
Answer:
y = -6x
Step-by-step explanation:
slope-intercept form: y = mx + b
slope↑ ↑y-intercept
parallel lines have the same slope, thus the slope is -6
substitute the y in (0, 0) and the slope of -6 into the equation y = mx + b:
=> y = -6x + 0
=> y = -6x
to solve.
