The slope-intercept form: y = mx + b

m - a slope
b - y-intercept

y = 4x - 3 ⇒ b = -3 → (0;-3)

if a slope m > 0 then the line increase

m = 4 > 0

Answer: Graph #4.

A)PA=2•AB<br> B)AB=1/2•PA<br> C)PA=PB<br> D)2•PA=PB

Digiron [165]

Answer:

Step-by-step explanation:

AB = PB + PA

PC is the perpendicular bisects of the segment BA.

Therefore PB = PA → AB = 2PB = 2PA → PB = PA = 1/2AB.

An ant walked on the coordinate plane from point A( − 3,1) to point B(1,25) by the shortest path. Find y-coordinate of the point

konstantin123 [22]

Answer:

Step-by-step explanation:

The shortest path is a straight line. The slope of that line is:

m = (25 − 1) / (1 − (-3))

m = 6

The point where the ant intersects the y-axis has an x-coordinate of 0. The slope between that point, and any other point on the line, is 6.

6 = (y − 1) / (0 − (-3))

y = 19

a carnival game consists of 3 dart throws at a target. The probability of scoring a hit on any one throw is 30%. Using the binom

Ghella [55]

Answer: Probability of scoring 2 hits = 0.63.

Step-by-step explanation:

Since we have given that

Number of dart throws at a target = 3

Probability of scoring a hit on any one throw = 30%

We will use "Binomial Distribution" i.e.

$P=^nC_rp^r(1-p)^{n-r}$

where,

n denotes number of dart throws at a target,

r denotes number of required throws

p denotes probability of success

(1-p) denotes probability of failure

So, Probability of success is given by

$\frac{30}{100}=\frac{3}{10}$

Probability of failure is given by

$1-\frac{30}{100}=\frac{70}{100}=\frac{7}{10}$

We will use "Binomial Distribution" i.e.

$P(X=2)=^3C_2(\frac{3}{10})^2\times (\frac{7}{10})\\\\P(X=2)=\frac{9}{100}\times \frac{7}{100}\\\\P(X=2)=\frac{63}{100}\\\\P(X=2)=0.63$

Hence, Probability of scoring 2 hits = 0.63.

To the nearest whole degree what angle measure has a tangent of 5.6922

Softa [21]

Answer:

<h3>80° has a tangent of 5.6922..</h3>

Step-by-step explanation:

We are given value of tangent trigonometric ratio = 5.6922.

We need to find the angle in degrees whose measure has a tangent of 5.6922..

So, we need to find the value of $tan^{-1}(5.6922)$ .

On plugging $tan^{-1}(5.6922)$ in calculator, we get

80.03°.

Now, we need to round it to the nearest whole degree.

Therefore, 80.03°≈ 80°.

<h3>Therefore, 80° has a tangent of 5.6922..</h3>
