Answer:
79
Step-by-step explanation:
Supplementary are angles that will add up to 180. So to find the missing angle we do 180 - 101 and get 79.

A quadratic equation x²+2(3x+p)=0 where p is a constant, has roots a and 2a, where a≠0
(a) find the value of a and of p
(b) hence, from a quadratic equation whose roots are a+1 and a-5
HELP ME PLISS
Answers
Answer:
a = -2 and p = 4.
Step-by-step explanation:
x²+2(3x+p)=0
x^2 + 6x + 2p = 0
For the general equation ax^2 + bx + c = 0, the sum of roots = -b/a and their product = c / a.
So here we have:
Sum of the roots:
a + 2a = -6/1 = -6
Product of the roots = 2a^2 = 2p/1 = 2p..
So 3a = -6 and
a = -2.
and
2(-2)^2 = 2p
8 = 2p
p = (-2)^2 = 4.
Answer:
see explanation
Step-by-step explanation:
Since x = a and x = 2a are roots, then substitute these values into the equation.
x = a
a² + 2(3a + p) = 0, that is
a² + 6a + 2p = 0 → (1)
x = 2a
(2a)² + 2(3(2a) + p) = 0
4a² + 12a + 2p = 0 → (2)
Solving simultaneously
Subtract (1) from (2) term by term to eliminate p
3a² + 6a = 0 ← in standard form
3a(a + 2) = 0 ← in factored form
Equate each factor to zero and solve for a
3a = 0 ⇒ a = 0
a + 2 = 0 ⇒ a = - 2
Since a ≠ 0 then a = - 2
Substitute a = - 2 into either of the 2 equations and solve for p
substituting into (1)
(- 2)² + 6(- 2) + 2p = 0
4 - 12 + 2p = 0
- 8 + 2p = 0 ( add 8 to both sides )
2p = 8 ( divide both sides by 2 )
p = 4
Thus a = - 2 and p = 4
--------------------------------------------
a + 1 = - 2 + 1 = - 1
a - 5 = - 2 - 5 = - 7
If x = - 1 and x = - 7 are roots then the corresponding factors are
(x + 1) and (x + 7) and the quadratic equation is the product of the factors, that is
(x + 1)(x + 7) = 0 ← expand left side using FOIL
x² + 8x + 7 = 0

Cristian says that when you raise a base number to a power of 3, it is impossible for the number to get smaller. Do you agree or disagree? Justify (prove) your answer.
Answers
Answer: I disagree
Step-by-step explanation:
I disagree with the statement from Cristian. When you raise a base number to a power of 3, it is possible for the number to get smaller.
For example, let's say our base number is negative 2, that is -2. Now let's find the cube of the number. This will be:
= -2^3 = -2 × -2 × -2 = -8
In this example, we can see that -8 is smaller than -2. This shows that the statement by Cristian is not correct.

Answer:

Step-by-step explanation:
Step one:
GIven data
let the haircut be x
and hair color be y in numbers.
so
18x+42y=288------------1
x+y=12---------------------2
from 1
x=12-y, put this in 2, we have
18(12-y)+42y=288
216-18y+42y=288
collect like terms
24y=288-216
24y=72
divide both sides by 24
y=72/24
y=3
put y= 3 in 2
x+3= 12
x= 12-3
x=9

Answers
Answer:

Step-by-step explanation:
Kindly check the picture attached for the solution diagram
Using the cosine formula (Diagram has two sides and an included angle)
x² = y² + z² - 2zy * cosX
x² = 150² + 60² - 2(150*60) * cos115
x² = 22500 + 3600 - 18000 * −0.422618
x² = 22500 + 3600 + 7607.1287
x² = 33707.128 miles
x = √33707.128
x = 183.59501
