The sketches show the graphs y=-x^2+16 and y=7

Mathematics
1 answer:
Tanzania [10]2 years ago
3 0

Answer:

7 = -x^2 +16

x^2 -16 = 7

x^2 -23 = 0

Using quadratic equation

x = -0 +- sqrt (23^2 - 4*1*23) / 2 * 1

x = sqrt (0 - -92) / 2

x = sqrt (92) / 2

x1 = 4.7958

x2 = -4.7958

the ojos del salado volcano has an elevation about 3 times as great as the khangar volcano. If the khangar volcani is 6,562 feet
Vlada [557]

Answer:

The approximate elevation of the "ojos del salado" volcano is 19,686 feet above sea level

Step-by-step explanation:

Let

y -----> elevation of the "ojos del salado" volcano

x -----> elevation of the "khangar" volcano

we know that

The elevation of the "ojos del salado" volcano is about 3 times as great as the khangar volcano

so

y=3x ----> equation A

we have

x=6,562\ ft

substitute the value of x in the equation A

y=3(6,562)=19,686\ ft

therefore

The approximate elevation of the "ojos del salado" volcano is 19,686 feet above sea level

HELLO! 20 PT ANSWER & BRAINLIEST!
beks73 [17]

Answer:

745 books are expected to be donated to the library at the end of Month 10

Step-by-step explanation:

There were 80 books donated at the library:

No=80

The number of books donated to a library is increasing by 25% each month:

There were 100 books donatd at the end of Month 1:

N1=100

N1=No+25%No

N1=No+(25/100)No

N1=No+0.25 No

N1=(1+0.25) No

N1=(1.25) No

(1) N1=(1.25)^1 No

N1=(1.25)^1 80

N1=(1.25) 80

N1=100


N2=N1+25%N1

N2=N1+(25/100)N1

N2=N1+0.25 N1

N2=(1+0.25) N1

N2=(1.25) N1

Replacing equation (1) in the equation above:

N2=(1.25) (1.25)^1 No

N2=(1.25)^(1+1) No

(2) N2=(1.25)^2 No


N3=N2+25%N2

N3=N2+(25/100)N2

N3=N2+0.25 N2

N3=(1+0.25) N2

N3=(1.25) N2

Replacing equation (2) in the equation above:

N3=(1.25) (1.25)^2 No

N3=(1.25)^(1+2) No

(3) N3=(1.25)^3 No


In general:

Nt=N(t)=(1.25)^t No

N(t)=(1.25)^t (80)

N(t)=80 (1.25)^t

where t is the number of the month

How many books are expected to be donated to the library at the end of Month 10?

t=10

N(10)=80 (1.25)^10

N(10)=80 (9.313225746)

N(10)=745.0580596

Rounding to the nearest whole number:

N(10)=745
