Equation in slope intercept form between points (1,-4) and (0,6)?
Vinvika [58]
Find the gradient:
m = y2-y1 / x2-x1
m = 6-(-4) / 0-1
m = 10 / -1
m = -10

Slope intercept form:
y = mx + c

Input the values from one of the points to find c (imputing (1,-4) to y=mx+c):
-4 = -10(1) + c
-4 = -10 + c
c = -4 + 10
c = 6

Therefore, the equation is:
y = -10x + 6

Benjamin threw a rock straight up from a cliff that was 48 ft above the water. If the height of the rock​ h, in​ feet, after t s
fomenos

Answer: It will take 4 seconds  for the rock to hit the​ water.

Step-by-step explanation:

Given : Benjamin threw a rock straight up from a cliff that was 48 ft above the water.

If the height of the rock​ h, in​ feet, after t seconds is given by the equation

h = -16 t^2+ 52 t + 48

To find : Time taken for the rock to hit the​ water.

When rock hit the water height becomes zero , i.e. put h = 0 , we get

-16 t^2+ 52 t + 48 =0

Divide equation by 2 , we get

-8t^2+26t+24=0

The Laue of x for ax²+bx+c =0 is x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}

So , t=\frac{-26\pm\sqrt{(26^{2}-4(-8)(24))}}{2(-8)}

t=\dfrac{-26\pm 38}{-16}\\\\ t=-\dfrac{-26+38}{-16}=-0.75\ \ t=\dfrac{-26-38}{-16}=4

Since t cannot be negative , so t= 4

Hence, it will take 4 seconds  for the rock to hit the​ water.

A state senator believes that 25% of all senators on the finance committee will strongly support the tax proposal she wishes to
sp2606 [1]

P(X=x)= nC_xp^x(1-p)^{n-x}Number of Senators be n=5
Probability that the Senators will strongly support the tax proposal be p=\frac{25}{100}=0.25
Let X be the number of Senators will strongly support the tax proposal.
Using Binomial Distribution,
P(X=x)=nC_xP^x(1-p)^{n-x}
Now Plug in the values of n and p,
P(X=x)=nC_xp^x(1-)^{n-x} [\tex]  To find the probability that 3 out of the 5 Senators will support the tax proposal is [tex] P(X= 3)=5C_3(0.25)^3(1-0.25)^{5-3}\\ =0.08789
