Answer:

cos y° = b divided by 6

Step-by-step explanation:

Trigonometric ratios :

$Sin \theta = \frac{Perpendicular}{Hypotenuse}$

We are given that sin y° = a divided by 6

$sin y^{\circ}=\frac{a}{6}$

On comparing

Perpendicular = a

Hypotenuse = 6

$Tan \theta= \frac{Perpendicular}{Base}$

tan y°=a divided by b

On comparing

Perpendicular = a

Base = b

So, $cos \theta = \frac{Base}{Hypotenuse}$

$Cos y^{\circ}=\frac{b}{6}$

So, Option d is true

cos y° = b divided by 6

A new, trendy department store is experiencing exponential growth across America. The chain began in 2004 when it opened 16 stor

QveST [7]

The equation is y=16(1.35)ˣ.

This equation is of the form y=a(1+r)ˣ, where a is the initial amount, r is the rate of growth expressed as a decimal number, y is the total, and x is the amount of time. For our problem, a is 16; b is 0.35 (35%=35/100=0.35). This gives us the equation above.

You have a rack that can hold 30 CDs. You can fit 7 more CDs on the rack before the rack is full. How many CDs are in the rack?

uysha [10]

X = number of cds on the rack

x + 7 = 30
x = 30 - 7
x = 23 <== so there are currently 23 cds on the rack

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Answer: -258

<u>Step-by-step explanation:</u>

Given the sequence {-8, 16, -32, 64, ... , a₇} we know the following

the first term (a₁) = -8
the common ratio (r) = -2
the number of terms (n) = 7

Input the information above into the Sum formula:

$S_n=\dfrac{a_1(1-r^n)}{1-r}\\\\S_7=\dfrac{-8(1-(-2)^7)}{1-(-2)}\\\\.\quad =\dfrac{-8(1-(-128))}{1+3}\\\\.\quad =\dfrac{-8(129)}{4}\\\\.\quad =-2(129)\\\\.\quad =-258$

While visiting a memorial, a person approximated the angle of elevation to the top of the memorial to be 35º. After walking 255

Alenkasestr [34]

Draw a diagram to illustrate the problem as shown in the figure below.

Let h the height of the hill. =

At position A, the angle of elevation is 40°, and the horizontal distance to the foot of the hill is x.

By definition,

tan(40°) = h/x h = x tan40 = 0.8391x

(1)

At position B, Joe is (x - 450) ft from the foot of the hill. His angle of elevation is

40 + 18 = 58°.

By definition, tan(58°) = h/(x - 450)

h = (x - 450) tan(58°) = 1.6003(x-450)

h = 1.6003x - 720.135 (2)

Equate (1) and (2).

1.6003x - 720.135 = 0.8391x 0.7612x = 720.135

x = 946.0523

From (1), obtain

h = 0.8391*946.0523 = 793.8 ft

Answer: The height of the hill is approximately 794 ft (nearest integer)
