Find all values of k for which the equation 3x2−4x+k=0 has no solutions.
This should be an inequality.

Answers

Answer 1

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

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.​

Answers

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.

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.

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?

Answers

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.

Coordinate of a function

The 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
