A ramp is constructed with the given dimensions. What is the height of the ramp?

Answer:

See below for answers and explanations to the first 5 problems

Step-by-step explanation:

Problem 1:

cos(x) = 2/3

sec(x) = ?

sec(x) = 1/cos(x)

sec(x) = 1/(2/3)

sec(x) = 3/2

Problem 2:

sinβ = -5/6

cscβ = ?

cscβ = 1/sinβ

cscβ = 1/(-5/6)

cscβ = -6/5

Problem 3:

secφ = 2

tanφ = √3

sinφ = ?

secφ = 1/cosφ

tanφ = sinφ/cosφ

tanφ = sinφ/cosφ

tanφ = sinφ(1/secφ)

√3 = sinφ(1/2)

2√3 = sinφ

Problem 4:

secθ = 8

tanθ = 3√7

cscθ = ?

secθ = 1/cosθ

tanθ = sinθ/cosθ

cscθ = 1/sinθ

tanθ = sinθ/cosθ

tanθ = sinθ(1/cosθ)

3√7 = sinθsecθ

3√7 = sinθ(8)

(3√7)/8 = sinθ

cscθ = 1/sinθ

cscθ = 1/((3√7)/8)

cscθ = 8/(3√7)

cscθ = (8√7)/21

Problem 5:

sinθ = 2/√5

cosθ = 1/√5

tanθ = ?

tanθ = sinθ/cosθ

tanθ = (2/√5)/(1/√5)

tanθ = (2/√5)(√5)

tanθ = 2

Strictly increasing functions:

Let a function f(a) for x = a, then,

f(a + h), for x = a + h,

If f(a + h) > f(a), we say this a strictly increasing function, as with increase in x, f(x) also increases.

In the given graph, there are straight lines so you can say increasing interval would have +ve slope.

For x = -5 to -4, it increases = [-5, -4]

For x = 1 to 3, it increases = [1, 3]

Answer: [-5, -4] , [1, 3]

Answer:

145

Step-by-step explanation:

Supplementary angles add up to equal 180 degrees

Thus, ∠ABC + ∠DEF = 180°

If ∠ABC = 35

Then 35 + ∠DEF = 180

180 - 35 = 145

Hence, ∠DEF = 145

Answer:

24

Step-by-step explanation:

Let n = number of sides

15n = 360

divide both sides of the equation by 15

n = 24

Answer:

24

Step-by-step explanation:

Let n = number of sides

15n = 360

divide both sides of the equation by 15

n = 24

Step-by-step explanation:

took the test

Answer:

66.35 feet

Step-by-step explanation:

We solve the above question using the Trigonometric function of Tangent

= tan θ = Opposite/Adjacent

θ = 53°

Opposite = Height of the tree = h

Adjacent = Point of the ground from the foot of the tree = 50 ft

Hence,

tan 53 = h/50ft

Cross Multiply

h = tan 53 × 50ft

h = 66.352241081 ft

Approximately to the nearest hundredth, the height of the tree = 66.35 feet

Answer: 88 m

A basketball court takes the shape of a rectangle and the perimeter of a rectangle is calculated by the formula:

= Length + Length + Width + Width

Slotting the figures in will give:

= 27 + 27 + 17 + 17

= 88 m

Answer:

C

Step-by-step explanation:

If you would recall one of the laws of exponents, when dividing powers of the same base you subtract their exponents. So for this expression:

6⁷ ÷ 6⁵ = 6^(7-5) = 6² =36

Answer:

x = 4 + 3/2y

y = -8/3 + 2/3x

1. Finding X

2x-3y=8

2x=8+3y

x+4+3/2y

2. Finding Y

2x-3y=8

-3y=8-2x

y=-8/3+2/3x

Answer:

1/3

Step-by-step explanation:

If the hour hand moves 30° each hour and there are 12 hours on the clock, the total degree it would move in 12 hours = 12 x 36 = 360 degrees

degrees moved in 4 hours = 4 x 30 = 120

fraction = 120 / 360

to express in its simplest form, divide both numerator and the denominator by 120

= 1/3

Option D

Dilation with scale factor 2, multiply by 2.

(x, y) → (2x,2y)

Step-by-step explanation:

J(2,4) → J'(4,8)

K(1,1)  → K'(2,2)

L(4,0) → L'(8,0)

Dilate with a scale factor of 2

Each set of JKL points multiplied by 2 to form J'K'L'

J(2*2, 2*4)

K(2*1, 2*1)  

L(2*4, 2*0)

Answer:

C should be correct and super sorry if its wrong

Step-by-step explanation:

Answer:

B. $5039.58

Step-by-step explanation:

compound interest formula: amount = p(1 + \frac{r}{n})^{nt}

p= principal ($2,300)

r= interest rate as a decimal (4% = 0.04)

n= number of times the principal is compounded per year (annually = onceper year so 1 time per year)

t= time in years (20 years)

new equation: amount = 2300(1+\frac{0.04}{1} )^{1*20}

That equation equals $2,739.58 which you add to the principal.

$2,739.58 + $2,300 = $5039.58

hope this helps :)

Answer:

2.2857

Step-by-step explanation:

To solve this I'm going to find Angle A

I have the adjacent and opposite side so using TOA is easiest

let a= angle

tan(a)=4/7

a=29.74488

Now that we have the angle A we can only look at triangle ABC

To solve for x we use TOA again

tan(29.74488)=x/4

4tan(29.74488)=x

x=2.2857
