Answer:

x=10 and x=-6

Step-by-step explanation:

f(x)=(x-2)²-64 (Given)

0=(x-2)²-64 (Set equation equal to 0)

64=(x-2)² (Add 64 to both sides)

±8=x-2 (Take the square root of both sides)

Because there are two possible roots, make 2 equations to find both:

8=x-2 and -8=x-2

10=x and -6=x

Answer:

38.16

Step-by-step explanation:

cosine = adjacent leg / hypotenuse

34 / x = cos 27

x = 34 / cos 27 deg

x ≈ 38.16

Answer:

we have

cos 27°=base/hypotenuse

cos27°=34/x

x=34/cos27°= 38.16is your answer

The function C represents a parabola that opens downward and intersects the x-axis at (3,0) and (-4,0). Option C is correct.

A function is a statement, rule, or law that establishes the connection between two variables. In mathematics, functions are everywhere and are necessary for constructing physical connections.

The general parabola equation is as follows: y=p (x-h)²+k or x=p(y-k)²+h, with (h,k) indicating the vertex.

The equation of the parabola is;

y=p (x-3)²+0

y=p(y-0)²+ (-4)

On combining both the equations;

f(x) = 8 (x-3) (x+4)

The function C represents a parabola that opens downward and intersects the x-axis at (3,0) and (-4,0).

Hence,option C is correct.

Answer:

1.) The 1ˢᵗ three term is (-32), (-7) and 18

2.) The 1ˢᵗ three term is 127, 106 and 85

Step-by-step explanation:

Here,

First Term = a₁ = - 32

Common Difference = (d) = 25

Now, For 1ˢᵗ three term,

n = 1

a₁ = - 32

n = 2

aₙ = a + (n - 1)d

a₂ = (-32) + (2 - 1) × 25

a₂ = (-32) + 1 × 25

a₂ = (-32) + 25

a₂ = -7

n = 3

aₙ = a + (n - 1)d

a₃ = (-32) + (3 - 1) × 25

a₃ = (-32) + 2 × 25

a₃ = (-32) + 50

a₃ = 18

Thus, The 1ˢᵗ three term is (-32), (-7) and 18

Here,

First Term = a₁ = 127

Common Difference = (d) = -21

Now, For 1ˢᵗ three term,

n = 1

a₁ = 127

n = 2

aₙ = a + (n - 1)d

a₂ = 127 + (2 - 1) × (-21)

a₂ = 127 + 1 × (-21)

a₂ = 127 - 21

a₂ = 106

n = 3

aₙ = a + (n - 1)d

a₃ = 127 + (3 - 1) × (-21)

a₃ = 127 + 2 × (-21)

a₃ = 127 - 42

a₃ = 85

Thus, The 1ˢᵗ three term is 127, 106 and 85

Answer: 35 trading cards

Step-by-step explanation:

Assume the trading cards collected by Trey is x.

That means that the number of trading cards collected by Abigail is 7x.

Relevant expression is:

7x + x = 40

8x = 40

x = 40/8

x = 5 trading cards

This means that Trey collected 5 trading cards

Abigail collected 7 times that figure so Abigail collected:

= 7 * 5

= 35 trading cards

Step-by-step explanation:

From Pythagorean theorem

x^2 = (10)^2 - (8)^2 = 36 or x =6

sin theta = opp/hyp = 6/10 = 3/5

cos theta = adj/hyp = 8/10 = 4/5

tan theta = opp/adj = 6/8 = 3/4

cot theta = 1/tan theta = 4/3

sec theta = 1/cos theta = 5/4

csc theta = 1/sin theta = 5/3

Answer:

692 ft^2

Step-by-step explanation:

Area of a circle = (pi)(radius)^2

Here,

Area of the circle = (3.14)(21 ft)^2 = 1385 ft^2

Area of half this circle = area of the semicircle = 1385 ft^2  /  2, or

Area of semicircle = 692 ft^2

Step-by-step explanation:

1. isosceles triangle

2.   3x + 15 = 90       x = 25

     x + 25 = 90        x = 65

     x + 55 = 90        x = 35

3. The size for DAB is 84

My reasoning is I went from one angle to another by subtracting 180 from my answers. For example angle 132 is supplementary to the missing angle next to it. I subtract 180 from 132 and get 48. That already solves the 2 equivalent angles in the triangle so I have 48+48+x = 180 because a full triangle equals 180. I get x = 84 then I do the same thing I did with angle 132. Angle 84 is supplementary to the missing angle next to it. I subtract 84 from 180 and get 96 then go diagonal from angle C (which is 96) to angle A. Those are supplementary so I subtract 96 from 180 and get 84.

C is a function

Step-by-step explanation:

For every input in a relation, there should only exist one unique output. For example, in option A, the input 1 has 3 outputs which does not make it a function since they all have to be unique. Additionally, B and D aren't functions for the same reasons. Therefore, C is a function.

Answer: [tex]80.2\ ft[/tex]

Step-by-step explanation:

Given

Zipline begins [tex]h=46\ ft[/tex] in the air

The angle of elevation is [tex]35^{\circ}[/tex]

Assume the length of the cable is l

from the figure, we can write

[tex]\Rightarrow \sin 35^{\circ}=\dfrac{46}{l}\\\\\Rightarrow l=\dfrac{46}{\sin 35^{\circ}}\\\\\Rightarrow l=80.19\approx 80.2\ ft[/tex]

The value of x will be 60.33. Then the tan 48° will be 67 / 60.33.

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

The right-angle triangle has angles of 48°, 42°, and 90°.

Then the value of x will be

tan 42° = x / 67

         x = 60.33

Then the tan 48° is given as

tan 48° = 67 / 60.33
