Answer: First option is correct.

Step-by-step explanation:

Since we have given that

$\dfrac{200x}{9x+1}+900$

i.e. $A(x)=\dfrac{200x}{9x+1}+900$

At x = 0

$A(0)=\dfrac{0}{1}+900=\$900$

∴ Her earning would be $900.

It means that the constant 900 represents the amount Kayla's bakery earns in a particular month when there are no online orders.

Hence, First option is correct.

Hi there!

The answer is A. The constant 900 represents the amount Kayla's bakery earns in a particular month when there are no online orders.

Since 900 is part of the cost that is added to the amount of money Kayla makes per online order (x), it must represent the amount Kayla's bakery makes without online orders.

Hope this helps!

A triangle with an area of 202.5 has a height that measures 15 find its base

Papessa [141]

The area = 1/2 * base * height

202.5 = 1/2 * base * 15

measure of the base = 202.5 / (1/2 * 15)

= 27 answer

I would really appreciate help with the following, along with work shown so I can understand how these were solved.

Alja [10]

First, you have to know the double angle formula:

sin 2A = 2 sin A cos A

cos 2A = cos² A − sin² A = 2 cos² A − 1 = 1 − 2 sin² A

tan 2A = 2 tan A / (1 − tan² A)

Next, find the other leg: 17^2-15^=64, √64 is 8, so the unknown leg length is 8.

sinα=15/17, cosα=8/17, tanα=15/8

sinβ=8/17, cosβ15/17, tanβ=8/15

Plug these values in the above formula, you'll have your answers.

For the half angles, know the half-angle formula:

sin(B/2) = ± √(1 − cos B)/2

cos(B/2) = ± √(1 + cos B)/2

tan(B/2) = (1 − cos B) / sin B = sin B / (1 + cos B)

refer to this website for details:

For the power reduction formula, please search for it. I tried to copy and paste here, but it wouldn't paste.

for number 4, factor the quadratic equation into (cscx-8)(cscx+1)=0

cscx=8 or cscx=-1

You may not have the csc button on your calculator. Recall that csc is 1/sin, so sinx=1/8 or sinx=-1, so x is either 7.18 or 270 degrees

Suppose you invest $750.00 in a fund earning 6% simple discount. A certain time later you withdraw the investment (principal and

barxatty [35]

Answer:

4.08 + 2 = 6.08 years

Step-by-step explanation:

we know that

Simple Interest(S.I.) = (P × R × T) ÷ 100

where, P = Principal = 750

R = Rate = 6%

T = unknown

⇒ S.I. = (750 × 6 × t)÷ 100

⇒ S.I. = 45t

Also, Amount = S.I + Principal

⇒ Amount = 750 + 45t

Now Formula for Compound Interest is:

$A = P(1+\frac{r}{100})^{t}$

where A = Amount

=1000

P = Principle

r = rate

t = total number of year

Here, P = 750 + 45t, r = 3.5% , and t = 2.

Putting all these values in above formula:

$1000 = (750 + 45t)(1+\frac{3.5}{100})^{2}$

⇒ $1000 = (750 + 45t)(1.071)$

⇒ t = 4.08

Hence, total time required will be 2 + 4.08 = 6.08 years.
