k is a prime number and f(x) = k has no solutions.
Find the possible values of k.
Answer:
Suppose x∈R is such that x+20x=p is a prime. Then x2−px+20=0 , and this equation has a solution x∈R if and only if p2–80≥0 . So the primes which admit no real solution are those that satisfy p<80−−√ , or 2 , 3 , 5 , and 7 . ■
Step-by-step explanation:
E? <3
The primes which accept no real solution exist as those that satisfy
p<[tex]\sqrt{80}[/tex], or 2, 3, 5, and 7.
What is a prime number?A prime number exists as a real number greater than 1 whose only factors that exist are 1 and itself. A factor exists as an entire number that can be divided evenly into another number. The first prime numbers exist 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29. Numbers that contain better than two factors exist named composite numbers.
If the function f(x) = (20/x) + x = k. Suppose x∈R exists such that x+20x=p exists a prime. Then [tex]$x^2-px+20=0[/tex], and this equation contains a solution x∈R if and only if [tex]$p^2-80[/tex] ≥ 0. So the primes which accept no real solution exist as those that satisfy p < [tex]\sqrt{80}[/tex], or 2, 3, 5, and 7.

find the outputs.. please help
Answer:
see below
Step-by-step explanation:
The steps are +2 then *4 then -8 then ÷2
Input is 5
5 +2 =7 *4 = 28-8 = 20 ÷2 = 10 Output is 10
Input is 9
9 +2 =11 *4 = 44-8 = 36 ÷2 = 18 Output is 18
Input is 14
14 +2 =16 *4 = 64-8 = 56 ÷2 = 28 Output is 28
Input is 18
18 +2 =20 *4 = 80-8 = 72 ÷2 = 36 Output is 36
Input is 23
23 +2 =25 *4 = 100-8 = 92 ÷2 = 46 Output is 46
Input is 7.5
7.5 +2 =9.5 *4 = 38-8 = 30 ÷2 = 20 Output is 20
Input is 11.54
11.54 +2 =13.54 *4 = 54.16-8 = 46.16 ÷2 = 23.08 Output is 23.08
Answer:
Output:
5 + 2 x 4 - 8 ÷ 2 = 9
9 + 2 x 4 - 8 ÷ 2 = 13
14 + 2 x 4 - 8 ÷ 2 = 18
18 + 2 x 4 - 8 ÷ 2 = 22
23 + 2 x 4 - 8 ÷ 2 = 27
7.5 + 2 x 4 - 8 ÷ 2 = 11.5
11.54 + 2 x 4 - 8 ÷ 2 = 14.54

Equation practice with angle addition
Answer:
m<BOC = 60°
Step-by-step explanation:
First, we will need to determine the value of x
m<BOC + m<AOB = m<AOC (angle addition postulate)
Substitute
9x + 42 + 7x + 30 = 104
Collect like terms
16x + 72 = 104
16x + 72 - 72 = 104 - 72
16x = 32
x = 32/16
x = 2
✔️m<BOC = 9x + 42
Plug in the value of x
m<BOC = 9(2) + 42
m<BOC = 18 + 42
= 60°

Luigi decided to grab lunch at Howell's Cafe with his friends. The bill for their meals was the $36.50. The restaurant charges a 7% tax. How much is the total bill?
Answer:
$39.055
Step-by-step explanation:
100% + 7% = 107%
[tex]\frac{y}{36.5} :\frac{107}{100}[/tex]
y · 100 = 107 · 36.5
100y = 3905.5
100y ÷ 100 = 3905.5 ÷ 100
y = 39.055
The height, h metres, of a springboard diver above the surface of the water t seconds after she leaves the board is given by h=-5t-12+7. Find the maximum height reached by the diver? How long does it take for the diver to reach maximum height? Find the height of the diving board?
Answer:
[tex]h_{max} = 14.2m[/tex]
[tex]t = 1.2[/tex]
The height of the diver is 7m
Step-by-step explanation:
Given
[tex]h(t) =-5t^2 + 12t + 7[/tex]
Solving (a): The maximum height reached
First, we calculate the time to reach the maximum height using:
[tex]t = - \frac{b}{2a}[/tex] --- maximum of a function
Where
[tex]a = -5; b = 12; c = 7[/tex]
So, we have:
[tex]t = -\frac{12}{-2 * 5}[/tex]
[tex]t = \frac{12}{10}[/tex]
[tex]t = 1.2[/tex]
So, the maximum height is:
[tex]h(t) =-5t^2 + 12t + 7[/tex]
[tex]h(1.2)=-5 * 1.2^2 + 12 * 1.2 + 7[/tex]
[tex]h(1.2)=14.2[/tex]
Hence:
[tex]h_{max} = 14.2m[/tex]
Solving (b): Time to reach maximum height
This has been calculated in (a)
[tex]t = 1.2[/tex]
Solving (c): Height of the board.
This can be calculated by setting [tex]t =0[/tex] --- i.e. the height of the diver before diving
So, we have:
[tex]h(t) =-5t^2 + 12t + 7[/tex]
[tex]h(0) = -5 * 0^2 + 12 * 0 + 7[/tex]
[tex]h(0) = 7[/tex]

The length of a rectangle is 16 units more than it's with. The area of the rectangle can be expressed as x^4 - 64.
Answer:
[tex]Width = x^2 - 8[/tex]
Step-by-step explanation:
Given
[tex]L = 16 + W[/tex]
[tex]Area = x^4 - 64[/tex]
Required
An expression for the width
We have:
[tex]Area = x^4 - 64[/tex]
Express as difference of two squares:
[tex]Area = (x^2 + 8)(x^2 - 8)[/tex]
For all acceptable values of x,
[tex]x^2 + 8>x^2 - 8[/tex]
So:
[tex]Length = x^2 + 8[/tex]
[tex]Width = x^2 - 8[/tex]
please help!! I'm really confused
Answer:
32 square units.
Step-by-step explanation:
The shape is made up of three parts, a rectangle in the middle, and two identical triangle on each side.
Rectangle: base = 2, height 8, area = 16
Each triangle: (vertical) base = 8, (horizontal) height = 2
Area = base * height /2 = 2*8/2 = 8
Total area = 8 + 16 + 8 = 32
how many solutions does 3(4+x)=7x-2(2x+3) have
Answer: no solutions
Step-by-step explanation:
Let's solve your equation step-by-step.
3(4+x)=7x−2(2x+3)
Step 1: Simplify both sides of the equation.
3(4+x)=7x−2(2x+3)
(3)(4)+(3)(x)=7x+(−2)(2x)+(−2)(3)(Distribute)
12+3x=7x+−4x+−6
3x+12=(7x+−4x)+(−6)(Combine Like Terms)
3x+12=3x+−6
3x+12=3x−6
Step 2: Subtract 3x from both sides.
3x+12−3x=3x−6−3x
12=−6
Step 3: Subtract 12 from both sides.
12−12=−6−12
0=-18

Helen rented a kayak at the lake. There is a charge of $10 as an initial fee and then $2 an hour for every hour that she uses the kayak. If the total charge is $22 , how many hours did she kayak?
Answer:
She kayaked for 6 hours.
Step-by-step explanation:
If $10 is the initial fee, subtract $22 - $10 = $12.
If it charges $2 per hour, divide $12 by $2 which equals 6 hours.
Answer:
6 hours
Step-by-step explanation:
Cost = fee + charge per hour * number of hours
22 = 10 +2h
Subtract 10 from each side
22-10 = 10+2h-10
12 = 2h
Divide
12/2 = 2h/2
6 = h
