Given a quadratic with one zero at 3 and a vertex at (-1,4), what is the other zero?

s2008m [1.1K]

Answer:

f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola. FYI: Different textbooks have different interpretations of the reference "standard form" of a quadratic function. Some say f (x) = ax2 + bx + c is "standard form", while others say that f (x) = a(x - h)2 + k is "standard form".

One satellite is scheduled to be launched from Cape Canaveral in Florida, and another launching is scheduled for Vandenberg Air

NeTakaya

Answer: $P\left ( A\right )=0.45$

$P\left ( B\right )=0.32$

Step-by-step explanation:

Given

$P\left ( A\cup B\right )=0.626$

$P\left ( A\cap B\right )=0.144$

and we know

$P\left ( A\cup B\right )=P\left ( A\right )+P\left ( B\right )-P\left ( A\cap B\right )$

$0.626=P\left ( A\right )+P\left ( B\right )-0.144$

$0.77=P\left ( A\right )+P\left ( B\right )$ -------1

as it is given

A and B are independent therefore

$P\left ( A\cap B\right )=P\left ( A\right )\cdot P\left ( B\right )$

$0.144=P\left ( A\right )\cdot P\left ( B\right )$

Substitute value of $P\left ( B\right )$ in 1

$0.77=P\left ( A\right )+\frac{0.144}{P\left ( A\right )}$

on solving $P\left ( A\right )=0.45$

$P\left ( B\right )=0.32$

. During a year, the probability a structure will be damaged by an earthquake (A) is 0.02, that it will be damaged by a hurrican

enyata [817]

Answer:

0.9506

Step-by-step explanation:

Pr(A) = 0.02

Pr(B) = 0.03

Pr(both) = 0.007

So,

Pr(Not A) = 1 - Pr(A)

= 1 - 0.02

= 0.98

Pr(Not B) = 1 - Pr(B)

= 1 - 0.03

= 0.97

Pr(Not by both) = 1 - Pr(both)

= 1 - 0.007

= 0.993

Thus,

Pr(Not B) or Pr(Not A) = 0.97 × 0.98

= 0.9056

∴ the probability that the house would not be damaged by a hurricane or an earthquake during the year is 0.9506.

The temperature has been going down at a constant rate. In 8 hours it went down 16

igomit [66]

<h3><u>Answer:</u></h3>

<h3><u>Solution ( step-by-step ): </u></h3>

The temperature changes -16 degrees ( negative because it wents down ) in 8 hours , So to know the chance per hour, We divide the number of degrees by the number of hours. If we call DT the change of Temperature each hour, we have that:

→ DT = -16 degrees/8 hours = -2 degrees / hour ..

Hope this helps you :) ..
