Answer:

y = -1/2x + 1

Step-by-step explanation:

Slope-intercept form:

y = mx + b

Use two of the ordered pairs and find the slope:

m = (1-2)/(0-(-2)) = -1/2

y-intercept is 1 as point (0, 1) is given in the table:

b = 1

The line is:

y = -1/2x + 1

Not sure what you’re asking, but, if you’re looking for the expanded form... hope that helps?

You use 4 gallons of water on 30 plants. At that rate how much water will you need for 45 plants?

Alja [10]

You would use 6 gallons of water to water 45 plants
4=30
$\frac{45}{30}$ = $\frac{3}{2}$
$\frac{3}{2}$ of 4 gallons = 6 gallons

Situation D: Suppose that, in a one-minute period during an electrical storm, the number of lightning strikes on a radar antenna

Crank

Answer:

21.77% probability that the antenna will be struck exactly once during this time period.

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

e = 2.71828 is the Euler number

$\mu$ is the mean in the given interval.

In this question:

$\mu = 2.40$

Find the probability that the antenna will be struck exactly once during this time period.

This is P(X = 1).

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

$P(X = 1) = \frac{e^{-2.40}*2.40^{1}}{(1)!} = 0.2177$

21.77% probability that the antenna will be struck exactly once during this time period.

Simplify the trigonometric expression sin(4x) +2 sin(2x) using Double-Angle Identities.

emmasim [6.3K]

Answer:

8sin(x)cos³(x)

Step-by-step explanation:

sin(4x) +2 sin(2x) = 2sin(2x)*cos(2x) + 2sin(2x) = 2sin(2x)(cos2x + 1)=

= 2sin(2x)(cos²x - sin²x + cos²x + sin²x)=²2sin(2x)*(2cos²x)=

= 4*2sin(x)*cos(x)*cos²(x)= 8sin(x)cos³(x)

Y = -4x + 8 Y=3/5x - 6/5

VladimirAG [237]

Answer:

x=2 and y=0

Step-by-step explanation:

Rewrite equations:

y=−4x+8;y=

−6

Step: Solvey=−4x+8for y:

y=−4x+8

Step: Substitute−4x+8foryiny=

−6

−4x+8=

−6

−4x+8+

−3

−6

−3

x(Add (-3)/5x to both sides)

−23

x+8=

−6

−23

x+8+−8=

−6

+−8(Add -8 to both sides)

−23

−46

−23

−46

−23

(Divide both sides by (-23)/5)

x=2

Step: Substitute2forxiny=−4x+8:

y=−4x+8

y=(−4)(2)+8

y=0(Simplify both sides of the equation)
