Answer:

927,154\ people

Step-by-step explanation:

we have a exponential function of the form

y=a(b^x)

where

y is the population of San Francisco

x is the number of years

a is the initial population

b is the base

r is the rate of grown

b=(1+r)

In this problem we have

r=1.26\%=1.26/100=0.0126

b=1+0.0126=1.0126

ordered pair (6, 870,887)

substitute in the exponential function y=a(b^x)

870,887=a(1.0126^6)

Solve for a

a=870,887/(1.0126^6)

a=807,857\ people

so

The exponential function is equal to

y=807,857(1.0126^x)

In 5 more years the number of years will be equal to

6+5=11 years

For x=11 years

substitute the value of x in the exponential function and solve for y

y=807,857(1.0126^{11})

y=927,154\ people

Which equation represents the line that passes through the points (6, –3) and (–4, –9)?
Delvig [45]
(6,-3)(-4,-9)
slope(m) = (-9 -(- 3) / (-4 - 6) = (-9 + 3) / -10 = -6/-10 = 3/5

y - y1 = m(x - x1)
slope(m) = 3/5
(6,-3)....x1 = 6 and y1 = -3
now we sub
y - (-3) = 3/5(x - 6) =
y + 3 = 3/5(x - 6) <==

How much of the 8% solution should we use to make 100g of a 3% solution?
sp2606 [1]
Suppose x grams of 8% solution should be mixed to make 100 g of 3% solution.
here we shall have:
the amount of 3% solution in the 100 g will be:
3/100*100=3 grams
the the equation will be, 8% of what quantity becomes 3g?
(8/100)*x=3
hence solving for x we shall have:
0.08x=3
x=3/0.08
x= 37.8 grams
The implication of this is that, when you have 37.5 grams of 8% solution, that will contain 3  of pure chemical and hence when you add more solvent on top of 37.5 g until you reach 100g, that will be 3% solution.

Bradley is returning home from a place that is 2 kilometers away. The function y = 2,000 − 90x represents Bradley's distance fro
12345 [234]

Answer:

The function is linear

The function changes at a constant rate

Step-by-step explanation:

If this function were to be graphed, a line would be seen. It is not an increasing function because he is getting closer to home so the distance from his house is decreasing
