Answer:

C: y = 115,000(1.05)x

Step-by-step explanation:

(havn’t actually did any math, but this is just process of elemination.)

{I’m just looking at the end of these, because the start is all the same}

if the number with the (perenthese) is below 1, it is a decreas, and the problem says it’s increasing by 5%. (1.5) Is equal to 50% increase so that means your answer would be (1.05) Because anything times 1 is the larger number, but when u add that 0.5, it’s raising the number up by 5%.

Answer:

C. y = 115 000(1.05)^x

Step-by-step explanation:

The formula for the amount accrued on an investment earning compound interest is

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

where

P = the amount of money invested (the principal)

r = the interest rate per period expressed as a decimal fraction

t = the number of periods

In this problem,

P = $115 000

r = 5 % = 0.05

By 2010, Luca's house will have increased in value for three years. Its value will be

$A = 115000(1 + 0.05)^{3}\\\text{The correct formula for the value of his home x years after 2010 is}\\ y = 115000(1.05)^{x}$

Rewrite as a mathematical equation and solve: 3 less than the product of 5 and a number is 42. Find the number.

Temka [501]

5x-3=42. To solve you add three to both sides making the equation 5x=45. Then you divide both sides by five, and you get 9 as your answer.

Which Two Numbers Add Up To Negative 26 And Multiply To 11?

Fynjy0 [20]

Xy=11
x+y=-26

x+y=-26
minus x both sides
y=-26-x

sub for y
x(-26-x)=11
-26x-x^2=11
add 26x+x^2 both sides
x^2+26x+11=0

ax^2+bx+c=0
x= $\frac{-b+/- \sqrt{b^{2}-4ac} }{2a}$

a=1
b=26
c=11

x= $\frac{-26+/-\sqrt{26^{2}-4(1)(11)} }{2(1)}$
x= $\frac{-26+/-\sqrt{676-44} }{2}$
x= $\frac{-26+/-\sqrt{632} }{2}$
x= $\frac{-26+/-2\sqrt{158} }{2}$
x= $-13+/-\sqrt{158}$

x= $-13+\sqrt{158}$ or $-13-\sqrt{158}$

aprox

x=-0.420195 or -25.5698

those are the numbers

Please solve for me ill give brainliest

Answer:

$\displaystyle (0, -1); maximum$

Step-by-step explanation:

First off, B is zero, so there is no phase shift, meaning that the vertex stays on the y-axis. Next, A is negative, so the parabola opens down, and whenever you have a parabola opening down, it does so at maximum. Finally, C represents our y-intercept, or in this case, our vertical shift. Our y-intercept is (0, −1), and so as our vertex, hence our answer.
