Answer:
x = 2
Step-by-step explanation:
The square of the tangent is equal to the product of the secant lengths to the near and far circle intersections.
(x +4)² = (2x -1)(2x -1 +9)
0 = (2x -1)(2x +8) -(x +4)² = (4x² +14x -8) -(x² +8x +16)
0 = 3x² +6x -24 = 3(x² +2x -8) = 3(x +4)(x -2)
This has solutions x = -4 and x = 2. Only the latter works in this geometry.
x = 2

Answer:
a=12 b=9
Step-by-step explanation:
u can substitute 3/4a in for b in a+b=12 since it is equal to b, giving you
a+3/4a=21
a=4/4a
4/4a+3/4a=21
7/4a=21
4/7(7/4a=21)
a=12
plug in 12 for a in either equation
b=3/4*12
b=9
(21=12+b) -12
9=b

Find the volume
V=bh
* B is length times width
Answer:
448 yd^3
Step-by-step explanation:
V = Bh where B is l * w
V = l*w*h
V = 8* 14* 4
=448 yd^3
Answer:
The volume of this rectangular prism is equal to [tex]448yd^{3}[/tex].
Step-by-step explanation:
From the question, we know the formula for the volume of a rectangular prism is V = Bh (where B is length times width, and "h" is the height).
Now we replace B (because we know that B is length times width) and get...
V = lwh (where "l" is the length of the prism, and "w" is the width of the prism.
Now we just substitute the values and get...
[tex]V = lwh = (14)(4)(8) = 448yd^{3}[/tex]
Tina brought $37.75 to the art supply store. She bought a brush, a sketchbook, and a paint set. The brush was 1 6 as much as the sketchbook, and the sketchbook cost 3 4 the cost of the paint set. Tina had $4.00 left over after buying these items.
Answer:
18.75=p
s=14.06
b=2.34
Step-by-step explanation:
37.75=b+s+p
-4
33.75=b+s+p
s=3/4p
b=1/6s
33.75=1/6(3/4p)+3/4p+p
33.75=3/20p+3/4p+p
(33.75=18/20p+p)20
675=18p+p)/18
37.50=2p)/2
18.75=p
s=3/4p
3/4(18.75)
s=14.06
b=1/6s
1/6(14.06)
b=2.34
37.75-4=18.75+14.06+2.34=35.15
im missing 50 cents somewhere its wrong but close i think sorry
The cost of a brush, a sketchbook and a paint set given the total amount with Tina is $2.25, $13.5 and $18 respectively.
How to write and solve equation?Total = $37.75
Amount left = $4.00
let
paint = pb = 1/6ss = 3/4p37.75 = p + b + s + 4
37.75 - 4 = p + 1/6s + 3/4p
33.75 = 1/6s + 1 3/4p
33.75 = 1/6(3/4p) + 1 3/4p
33.75 = 3/24p + 7/4p
33.75 = 3+42 / 24p
33.75 = 45/24p
p = 33.75 ÷ 45/24
= 33.75 × 24/45
= 810/45
p = $18
substitute into
s = 3/4p
= 3/4 × 18
= 54/4
s = $13.5
b = 1/6s
b = 1/6 × 13.5
b = 13.5/6
b = $2.25

HELP ME ASAP PLIS. This is the last question I don’t get it please help me people
Answer:
Component Form: v = <-1,6>
Magnitude of v: ||v|| = √37
Direction of v: θv = 100° (to the nearest degree)
Step-by-step explanation:
Component Form: v = <(5-6),(3-(-3))> = <-1,6>
Magnitude of v: ||v|| = √[(-1)²+(6)²] = √(1+36) = √37
Direction of v: α = tan⁻¹|6/-1| = tan⁻¹|-6| = tan⁻¹(6) = 80.53° which is your reference angle, but to verify that the angle is in the second quadrant, you'll need to do θv = 180° - 80.53° = 99.47°, therefore your direction angle is θv=100° to the nearest degree.

Answer:
Step-by-step explanation:
3x + 4y = 17
5x - 4y = 7
you can thus cancel out 4y
Hence
8x = 24
Hence x = 3
Substituting’
3(3) + 4y = 17
9 + 4y = 17
Hence 17 - 9/4
= y = 2

What is the range of the function shown in the graph below?
Answer:
y= -3/2X + 2
Step-by-step explanation:
we get the gradient by picking any two points from the graph( it a linear graph)
using the point:
(x,y)= (-2,5) , (4,-4)
using M= (y2-y1)/x2-x1)
we get our gradient to be -9/6 which is
-3/2
using the equation of a straight line graph which is
y-y1=m(x-x1) and the point (4,-4)
we get
y-(-4)=-3/2(x-4)
----> y+4= -3/2x + 6
make y subject of the formula to take the form
y=mx+c
we get :
y=-3/2x + 2

Answer:
5(2.2y + 3.4) = 5(y - 2) + 6y
Step-by-step explanation:
In order to answer this question, one must solve each of the equations until one has reached a conclusion that the parameter (y) has no solution in the given circumstance.
Equation 1
13y + 2 - 2y = 10y + 3 - y
Simplify, combine like terms;
11y + 2 = 9y + 3
Inverse operations,
11y + 2 = 9y + 3
-9y
2y + 2 = 3
-2
2y = 1
/2
y = 0.5
Equation 2
9(3y + 7) - 2 = 3(-9y + 9)
Distribute, multiply every term inside the parenthesis by the term outside of it;
(9)(3y) + (9)(7) - 2 = (3)(-9y) + (3)(9)
Simplify,
27y + 63 - 2 = -27y + 27
27y + 61 = -27y + 27
Inverse operations,
27y + 61 = -27y + 27
+27y
54y + 61 = 27
-61
54y = 34
/54
y = [tex]\frac{17}{27}[/tex]
Equation 3
32.1y + 3.1 + 2.4y - 8.2 = 34.5y - 5.1
Simplify, combine like terms;
34.5y - 5.1 = 34.5y - 51
As one can see, this equation is an identity, meaning that any value can be substituted into the parameter (y) to produce a true result.
Equation 4
5(2.2y + 3.4) = 5(y - 2) + 6y
Distribute, multiply every term in the parenthesis by the term outside of it;
(5)(2.2y) + (5)(3.4) = (5)(y) + (5)(-2) + 6y
Simplify,
11y + 17 = 5y - 10 + 6y
11y + 17 = 11y - 10
Inverse operations,
11y + 17 = 11y - 10
-11y
17 = -10
One can see that this equation produces a false result since it is common knowledge that (17) cannot equal (-10). Therefore, this equation has no solutions.
A cylinder has a height of 5 ft and a volume of 80 ft3. What is the radius?
Answer:
The radious would be 2.26
Step-by-step explanation:
Answer:
r = 2.26 ft
Step-by-step explanation:
v = πr²h
80 = πr²(5)
Divide both sides by
16 = πr²
Divide both sides by π (using 3.14 )
5.0955414013 = r²
Take the square root of both sides
r = 2.2573305919
Rounded
r = 2.26 ft
