Answer:
k>4/3
Step-by-step explanation:
The given quadratic equation is:
3x^2 - 4x + k = 0
To find, the value of k = ?
you use
Discriminant, D = - 4ac
= - 4(3)(k)
= 16 - 12k
The condition of no solutions.
D < 0
16 - 12k < 0
16<12k
4/3<k
⇒ k>4/3

Marina bought a bag of 10 chocolate cookies, 35 vanilla cookies, and 30 peanut butter cookies.
If she selects a cookie from the bag without looking, what is the probability she selects a peanut butter cookie?
Answer:
[tex]\frac{2}{5}[/tex]
Step-by-step explanation:
1) Add all the values.
= 10 + 35 + 30
= 75
2) 75 will be the denominator and the one required will be the numerator.
Since there are 30 peanut butter cookies, the probability is [tex]\frac{30}{75}[/tex].
3) Simplify the fraction if necessary.
Divide both sides by 15.
= [tex]\frac{2}{5}[/tex]

Step-by-step explanation:
-7 / -4/5
Invert the second fraction and multiply:
= -7 * -5/4
= 35/4
= 8 3/4.

Coordinate of a functionThe coordinate of a function are written in the form (x, y)
Given the amount of money Emily spends, after r rides, at a carnival
is modeled by the function y = 8r + 20
We are to determine the coordinate that satisfies the function
For the coordinate (15, 140)
If r = 15, then
y = 15(8) + 20
y = 140
Hence the coordinate (15, 140) satisfy the function
For the coordinate (11, 108)
If r = 11, then
y = 11(8) + 20
y = 108
Hence the coordinate (11, 108) satisfy the function

Step-by-step explanation:
In order to estimate how many pizzas were eaten, we need to subtract the amount of pizza left from the original amount. The amount of pizza left is 5/6 + 1 3/4. 5/6 is about 1 and 1 3/4 is about 2. 1 + 2 = 3 pizzas eaten.
The original amount of pizzas, 8, minus the amount of pizzas eaten, 3, is 5.. We can estimate that 5 pizzas were eaten.

Step-by-step explanation:
Your going to have the divide y by x so (y ÷ x)
5÷2 = 2.5
10÷4 = 2.5
15÷6 = 2.5
They all end up having the same answer. So when you divide y by x, you have to have the same answer for every single one.

Find an equation for the line that passes through the points (-6, 3) and (6, -6).
Answer:
[tex]y = -\frac{3}{4}x-\frac{3}{2}[/tex]
Step-by-step explanation:
First, calculate the slope of the line:
[tex]m = \frac{y_2-y_1}{x_2-x_1}\\m = \frac{(-6) - 3}{6 - (-6)}\\m = \frac{-9}{12}\\m = \frac{-3}{4}[/tex]
Next, calculate the y-intercept:
Choose any point on the line.
[tex](-6,3)[/tex]
Solve for [tex]b[/tex].
[tex]y = mx + b\\b = y - (mx)\\b = 3 - (\frac{-3}{4} * -6)\\b = 3 - \frac{9}{2}\\b = \frac{-3}{2}[/tex]
Finally, create the equation:
[tex]y = -\frac{3}{4}x-\frac{3}{2}[/tex]

there are five geometric mean between a and b. if second and last mean are 2 and 16 respectively, find the value of a and b.
Answer:
a = 1/2, b = 32.
Step-by-step explanation:
Second = a1r and fifth = a1r^4 where r = common ratio and a1 is the first mean after a.
So 1ar^4 / a1r = r^3 = 16/2
r^3 = 8
r = 2.
So a1 = 1.
The 5 means are 1, 2, 4, 8, 16
S0 a = 1/2 = 1/2 and b = 2*16 = 32.
