Answer:

f(x) = 15 (3) ^x

Step-by-step explanation:

The form of an exponential function is

y = a b^x

a is the initial value  so a = 15

y = 15 b^x

b > 1 when there is growth so

f(x) = 15 (3) ^x

what does this mean when a rhombus is split into 2 triangles ; what's the formula to find the value of x? also it's about polygons

Answers

Answer/Step-by-step explanation:

The rhombus when split into two triangles will give us two equilateral triangles that are congruent to each other.

Therefore:

The two bases of both triangles will have equal angle measures of 4x + 5 each and a third angle measure of 8x - 6.

✅Formula to find the value of x:

(8x - 6) + 2(4x + 5) = 180° (sum of triangle)

8x - 6 + 8x + 10 = 180

8x + 8x - 6 + 10 = 180

16x + 4 = 180

16x + 4 - 4 = 180 - 4

16x = 176

16x/16 = 176/16

x = 11

x^2 + y^2 + 8x - 6y-15=0

4 1/3 inches by 5 1/3 inches. Find the area of a rectangular

Answers

Answer:

23 1/9 sq. inches

Step-by-step explanation:

Start by making 4 1/3 into 13/3 and 5 1/3 into 16/3. You can find area by multiplying one side by another, so we multiply 13/3 and 16/3. We can multiply the numerators (Top) of the fractions and put them over the denominators (Bottom) of the fractions multiplied for our result. 13 * 16 is 208 and 3 * 3 is equal to 9. The simplified form is 23 1/9.

The average price of a two-bedroom apartment in the uptown area of a prominent American city during the real estate boom from 1994 to 2004 can be approximated by p(t) = 0.12e0.10t million dollars (0 ≤ t ≤ 10) where t is time in years (t = 0 represents 1994). What was the average price of a two-bedroom apartment in this uptown area in 2002, and how fast was the price increasing? (Round your answers to two significant digits.)

Answers

Answer:

Step-by-step explanation:

Average price of a two bedroom apartment can be approximated by the equation,

p(t) = [tex]0.12e^{0.10t}[/tex]

Here, t represents the duration from year 1994.

Duration from year 1994 to year 2004 = 10 years

p(10) = [tex]0.12e^{0.10\times 10}[/tex]

        = 0.12e

        = 0.3262

        ≈ 0.33 million

Cost of the apartment in 2004 was 0.33 million.

Let the equation to calculate the rate of increase in the price is,

p(t) = [tex]0.12(1+\frac{r}{100})^t[/tex]

Cost of the apartment after 10 years = 0.33

0.33 = [tex]0.12(1+\frac{r}{100})^{10}[/tex]

[tex]\frac{0.33}{0.12}=(1+\frac{r}{100})^{10}[/tex]

2.75 = [tex](1+\frac{r}{100})^{10}[/tex]

[tex](1+\frac{r}{100})=(2.75)^{0.10}[/tex]

1 + [tex]\frac{r}{100}=1.106[/tex]

[tex]\frac{r}{100}=0.106[/tex]

r = 10.6%

Therefore, price of the apartment is increasing with 10.6%

Tamara is 7 years older than her sister. The sum of their age is 27.
What is Tamara's age ?

Answers

Answer:

17 years old.

Step-by-step explanation:

If Tamara was 7 years younger, she would be as old as her sister. In that case, the sum of their ages would be 20, and since they'd both be the same age, 20 would just be Tamara's sister's age doubled. Half of 20 is 10, so Tamara's sister must be 10 years old, and at 7 years older, Tamara must be 17.

Answer:

17

Step-by-step explanation:

Tamara = x+7  

sis= x

 

x+x+7= 27

2x= 27-77  

x= 20/ 2= 10  

tamara = 10+7 = 17

many fewer than the number of hits predicted by the
line of best fit?
A) 10
B) 20
C) 30
D) 10

Answers

I think the answer B step by step

The actual number of hits the player had is approximately 10 fewer than the number of hits predicted by the line of best fit

How to interpret the scatter plot?

From the complete question, we have the following highlight:

The blue line is the predicted number of hitsThe red line is the actual number of hits.

From the graph, we have the following readings at x = 450

Actual readings y = 123 Predicted readings y = 113

Calculate the difference

d = 123 - 113

Evaluate the difference

d = 10

Hence, the actual number of hits the player had is approximately 10 fewer than the number of hits predicted by the line of best fit
