Answer:

domain is set of all real numbers

Range is y\leq 16

Step-by-step explanation:

f(x)=-x^2-2x+15

Domain is the set of x values for which the function is defined

In f(x), we have y values for all x values, So there is no restriction for x

Hence domain is set of all real numbers

Range is the set of all y values for which the function is defined

From the graph of the given function f(x), the maximum point that is vertex at (-1,16)

The range of the function is y<=16

Range is y\leq 16

Answer:

Domain is all real numbers

y ≤ 16

Step-by-step explanation:

The domain is the set of x values that the graph covers. There is no restriction on the x values. The domain is all real numbers.

The range is the set of y values that the graph covers. The highest the y values go is 16 at the top of the parabola. So the range is y ≤ 16.

If the simple interest on ​$3,000 for 8 years is ​$1,680​, then what is the interest​ rate?
madam [21]

We need to use the formula for simple interest which is
I= prt
Where I is the amount of money you earned or pay in interest
p is the principal, the amount you deposited or borrowed
r is the interest rate expressed as a decimal
t is time in terms of years

In this problem, I= 1,680
p= 3000
t= 8
'. r is what we are looking for.

Substituting the numbers into the simple interest formula, we get
I=. p r t
1,680=(3000)(r)(8). Multiplying
1,680= 24,000r Divide both sides by 24,000
0.07= r
So, the percentage is (0.07)(100)= 7%...

HEEELLLPPP PLEEAAASEEE
Pavel [41]

Answer:

B.  y = 2.5

Step-by-step explanation:

Diane's average speed=  25/y  km/h.

Ed's speed= (25/y) - 6 km/h.

Ed walks 25-3 = 22 km.

Consider Ed's journey:

Speed = distance / time so:

(25/y) - 6  = 22 / (y + 3)    ( 3 hours longer = y + 3)

(25 /y - 6)(y + 3) = 22

25 + 75/y - 6y - 18 = 22

6y - 75/y = 25 - 18 - 22

6y - 75/y + 15 = 0

6y^2 + 15y - 75 = 0

2y^2 + 5y - 25 = 0

(2y - 5 )(y + 5) = 0

y = 2.5, -5.

y = 2.5   ( as it must be positive.
