Write a quadratic equation that has 2 and 8 as solutions.
Find the equation with 1 as the coefficient of the quadratic term.
Answer:
[tex]x^2-10x+16[/tex]
Step-by-step explanation:
The way I would find the equation is by finding the factored form of the equation form. That equation would be (x-2)(x-8). These are correct because if you set both of these equal to zero, your x-values will be equal to 2 and 8.
x-2=0
x=2
x-8=0
x=8
If you want the standard form of the equation, all you have to do is multiply it out.
[tex](x-2)(x-8)\\x(x-8)-2(x-8)\\x^2-8x-2x+16\\x^2-10x+16[/tex]

√3(√6+√15)
simplify to the simplest form possible
Answer:
√3(√6+√15)
= 3**1/2(6**1/2 + 15**1/2)
= 3**1/2 · 6**1/2 + 3**1/2 · 15**1/2
= 18**1/2 + 45**1/2
= (2×9)**1/2 + (5×9)**1/2
= 2**1/2 · 9**1/2 + 5**1/2 · 9**1/2
= 2**1/2 · 3 + 5**1/2 · 3
= 3(√2 + √5)

Answer:
.33
Step-by-step explanation:
m=male
f=female
a=attended the review
P(A|M)= .2
P(A|F)= .4
We want: F∩A+M∩A
Recall the conditional probability formula (A|B)=(A∩B)/B
.2*.35+.4*.65= .33
A loan is payed off in 15 years with a total of 250,000. It had 4% interest
Answer:
5.2%po joke Lang Hahahahahahah
Answer:
$137,339.88
Step-by-step explanation:
Use the compound interest formula and substitute the values given:
$250,000=P(1+0.0412)12(15)
Simplify using order of operations:
$250,000=P(301/300)180
Solve for P:
P=$250,000(301/300)180≈$137,339.88

In a fishing derby, jimmy caught six more fish than his sister kelly. How many fish did each person catch if they caught a total of 20 fish?
Please help me understand
Answer:
2
Step-by-step explanation:
The scaled factor has to be 2 because 4*2=8. You can check 2 is the correct answer by doing 8/2, which is 4. The scaled factor has to be proportional so if one side of ABC was 2 but the same side on ABC prime or A’B’C’ was 10 it would not be proportional, not a scaled factor. Because 2*10 is 5, not 8. But it does not give any other side lengths so it is 4.
20 points!

Find the x-intercept and y-intercept of the line. 7x+5y=-15
Answer:
The x-intercept is (-2 1/7, 0).
The y-intercept is (0, -3).
Step-by-step explanation:
To find the y-intercept, substitute x with zero.
To find the x-intercept, substitute y with zero.
Finding the y-intercept by substituting x with zero:
7*0 + 5y = -15
5y = -15
y = -3
The y-intercept is (0, -3).
Finding the x-intercept by substituting y with zero:
7x + 5*0 = -15
7x = -15
x = -15/7
x = -2 1/7
The x-intercept is (-2 1/7, 0).

Sara says, "If you subtract 12 from my number and multiply the difference by - 3, the result is
- 45." What is Sara's number?
Answer:
3
Step-by-step explanation:
Answer:
[tex]27[/tex]
Step-by-step explanation:
Let Sara's number be [tex]x[/tex]. Now, we can build an equation.
We have that [tex]-3(x-12)=-45[/tex]. Aha! Now we have a path to the solution!
We can divide both sides of the equation by [tex]-3[/tex] to get [tex]x-12=15[/tex].
Lastly, we add [tex]12[/tex] to both sides to get [tex]x=27[/tex].
So, Sara's number is [tex]\boxed{27}[/tex].
Find the values of x, y, and z in the triangle to the right
Answer:
x = 36 , y = 64 , z = 80
Step-by-step explanation:
Exterior angle equals the sum of opposite interior angle.
3x + 8 = x + z
3x - x - z = -8
2x - z = -8 ------------ (I)
z + 3x - 8 = 180 {linear pair}
3x + z = 180 + 8
3x + z = 188 --------------(II)
Add (I) and (II) and z will be eliminated and we can find the value of 'x'
(I) 2x - z = -8
(II) 3x + z = 188 {Now add}
5x = 180
x = 180/5
x = 36
Plugin x = 36 in equation (II)
3*36 +z = 188
108 + z = 188
z = 188- 108
z = 80
x + y + z = 180 ----------------(III) {angle sum property of triangle}
36 + 80 +y = 180
116 + y = 180
y = 180 - 116
y = 64

Answer:
[tex]2\sqrt{29}+\sqrt{53}+5[/tex]
Step-by-step explanation:
The distance between A and B is a vertical distance of [tex]2[/tex] and a horizontal distance of [tex]5[/tex]. By the Pythagorean Theorem, [tex]AB=\sqrt{2^2+5^2}=\sqrt{29}[/tex].
The distance between B and C is [tex]5[/tex] by counting squares.
The distance between C and D is a vertical distance of [tex]2[/tex] and a horizontal distance of [tex]7[/tex]. By the Pythagorean Theorem, [tex]CD=\sqrt{2^2+7^2}=\sqrt{53}[/tex].
The distance between D and A is a vertical distance of 5 and a horizontal distance of [tex]2[/tex]. By the Pythagorean Theorem, [tex]DA=\sqrt{5^2+2^2}=\sqrt{29}[/tex].
So, the answer is [tex]\boxed{2\sqrt{29}+\sqrt{53}+5}[/tex]
