Answer:
y = x^2 + 15x + 56
Step-by-step explanation:
The solutions (where the trinomial = 0) is the factors that will turn the trinomial into 010.
(x + 7)(x + 8) = 0
This means that either -7 will turn the trinomial into 0 or - 8 will.
The trinomial is
x^2 + 8x + 7x + 56 will turn the trinomial to 0.
y = x^2 + 15x + 56 when either - 7 or - 8 is put in for x.
y = (-7)^2 + 15(-7) + 56
y = 49 - 105 + 56
49 + 56 = 105
y = 105 - 105 = 0
y = (-8)^2 - 15(-8) + 56
y = 64 - 120 + 56
y = 120 - 120= 0
No other number will turn the trinomial into 0.

f(x) = х2 + 2x – 10
f(x) = х2 - 2x – 10
f(x) = х2 + 3х – 10
f(x) = х2 – 3х – 10
calculate the perimeter of a quarter circle 2mm use pi=3.14
Answer:
Step-by-step explanation:
If the radius of the circle is 2mm, the circumference is 4π mm.
Arc length of the quarter circle = π mm.
Perimeter of the quarter circle = arc length + 2 radii = 4π + 4 mm = 16.56 mm

The two trapezoids are congruent. What is the value of x?
Answer:

Step-by-step explanation:
Please help me solve these are quadratic equations: I
Answer:
[tex]\boxed {\boxed {\sf a= 3, b=7, c=2}}[/tex]
[tex]\boxed {\boxed {\sf Y-intercept = c }}[/tex]
[tex]\boxed {\boxed {\sf Minimum}}[/tex]
Step-by-step explanation:
a. a, b, c
Quadratic equations in standard form are written as:
[tex]f(x)= ax^2+bx+c[/tex]
The exponents are listed from greatest to least. The quadratic is already in this form, so match up the variables and values in the equation.
[tex]f(x)= 3x^2+7x+2[/tex]
[tex]a=3 \\b=7 \\c=2[/tex]
b. Y-intercept
The y-intercept for a quadratic is c.
You can also substitute 0 in for x, because the y-intercept occurs when the quadratic crosses the y-axis (at x=0).
[tex]f(0)= 3(0)^2+7(0)+2[/tex]
[tex]f(0)=3(0)+7(0)+2\\f(0)= 0+0+2\\f(0)=2[/tex]
We know that c=2, so the y-intercept is c.
c. Maximum/minimum
The entire quadratic is positive, so the quadratic opens up and has a minimum.

-4x + 21 > -3
What could x be??
Answer:
x < 6
Step-by-step explanation:
subtract 21 on both sides
-4x > -24
divide both sides by -4 and flip the sign (bc you're dividing by a negative)
x < 6

Find the probability that an adult resident has 3 or more
vehicles. Give your answer as a number between 0 and 1.
Answer:
Step-by-step explanation:
Number of Vehicles Probability
0 0.04
1 0.41
2 0.38
3 0.13
4 0.03
5 0.01
X= 1
.13+.03+.01=0.17 (the amount with 3 or more cars)
0.17/1(Total amount of all probability)= 0.17 has 3 or more cars.
Probability is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
The probability that an adult resident has 3 or more is 0.17
What is probability?
It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
The probability distribution of the number of vehicles is given as,
P(x) where x is the number of vehicles.
P(0) = 0.4
P(1) = 0.41
P(2) = 0.38
P(3) = 0.13
P(4) = 0.3
P(5) = 0.1
The probability that an adult resident has 3 or more.
= P(3) + P(4) + P(4)
= 0.13 + 0.03 + 0.01
= 0.17
Thus,
The probability that an adult resident has 3 or more is 0.17
