Answer :
X1 = -1
X2 = 7

Reason :
Substitute X for 0
So

A curve passes through the point (0, 5) and has the property that the slope of the curve at every point P is twice the y-coordin

Anit [1.1K]

Answer:

$y=5e^{2x}$

Step-by-step explanation:

Let (x,y) represents a point P on the curve,

So, the slope of the curve at point P = $\frac{dy}{dx}$

According to the question,

$\frac{dy}{dx}=2y$

$\frac{1}{y}dy=2dx$

Integrating both sides,

$\int \frac{dy}{y}=2dx$

$ln y=2x+ln C$

$ln y-ln C = 2x$

$ln(\frac{y}{C})=2x$

$\frac{y}{C}=e^{2x}$

$\implies y=Ce^{2x}$

Since, the curve is passing through the point (0, 5),

$5=Ce^{0}\implies C=5$

Hence, the required equation of the curve is,

$y=5e^{2x}$

A purchasing agent for a trucking company is shopping for replacement tires for their trucks from two suppliers. The suppliers’

ohaa [14]

Answer:

C. the life of Supplier B's tires is more predictable than the life of Supplier A's tires.

Step-by-step explanation:

A: The distributions have the same mean, but different standard deviation. They are not the same distribution.

B: The distributions have the same mean, which means on average the tire lifetimes are the same from both suppliers.

C: A smaller standard deviation means values tend to be closer to the mean, hence more predictable. <em>Supplier B's tires have a more predictable life</em>.

D: "Dispersion" is another way to describe the measure provided by standard deviation. Supplier B's tires have a lower tire life dispersion.

Write an exponential function in the form y = abx that goes through points (0,16)<br>and (2,400).

barxatty [35]

Answer:

y = 16 $(5)^{x}$

Step-by-step explanation:

Use the given points to find the values of a and b

Using (0, 16), then

16 = a $b^{0}$ ( $b^{0}$ = 1 ), thus

a = 16

y = 16 $b^{x}$

Using (2, 400), then

400 = 16b² ( divide both sides by 16 )

b² = 25 ( take the square root of both sides )

b = $\sqrt{25}$ = 5

Thus

y = 16 × $5^{x}$ ← exponential function

A 64-ounce container of coconut milk costs 3.32. A 120-ounce container of the same milk costs 5.90

Marysya12 [62]

Answer: It would be cheaper to by the 120 ounce, instead of two 64 ounces.

Step-by-step explanation:

That’s because it would be $6.64, for two 64 ounces. $5.90 is cheaper than $6.64. Therefore it would be cheaper to get the 120 ounce.
