Answer:
r = 4, s = 3, t = 5Step-by-step explanation:
Solving quadratic equation:
5x² - 8x + 5 = 0x = (-b ± √b²-4ac)/2ax = (8 ± √8²-4*5*5)/2*5x = (8 ± √64-100)/10x = (8 ±√-36)/10x = (8 ± 6i)/10x = (4 ± 3i)/5x = (r ± si)/t

You and three friends are going to the fair. The cost for
parking is $5 per car and admission to the fair is $19 per person. If you have
a total of $113, how much can each person spend on food?
Answer:
$17 on food per person
Step-by-step explanation:
The cost of parking a car is $5
Assuming that the friends used one car, then the parking cost=$5
Admission cost is 19
For three people, Admission cost =19*3=57
TOTAl COSTS=Parking cost+Admission cost
TOTAl COSTS=57+5=62
Remaining amount can be used for food
FOOD= 113-62=51
Therefore each person can spend 51/3=$17 on food
I hope this was helpful and clear to follow
Answer:
$8
Step-by-step explanation:
19 x 4 + 5 + c =113
81 + c =113
-81 -81
c =32
32 divided by 4 ppl = 8

Answer:
C
Step-by-step explanation:
The distance around the circle is asking for the circumference of the circle.
Since we know that the diameter is 21 and the equation for the circumference of a circle is 2*pi*r and since 2*r is just the diameter, we can say that the circumference is 21*pi, which would be C.

Answer:
no solution
Step-by-step explanation:
You attempt to solve this the same way you would an equation.
4(x +1) ≤ 4x +3 . . . . . . given
4x +4 ≤ 4x +3 . . . . . . . eliminate parentheses
4 ≤ 3 . . . . . . . . . . . . . . subtract 4x from both sides
This is a false statement. There are no values of x that will make it true. So, there is NO SOLUTION.

What is logarithm?In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x
Given
B(t)=[tex]100.2^{\frac{t}{10} }[/tex] = 10000
[tex]2^{\frac{t}{10} } = 100\\t = 100\frac{ln 10}{ln 2} = 66.44[/tex]

x=-2y+56
y=3x+5
y=4x+8
Find X
Answer:
The value of x is -3.
Step-by-step explanation:
It is given that:
y=3x+5 Eqn 1
y=4x+8 Eqn 2
Putting value of y from Eqn 2 in Eqn 1
4x + 8 = 3x + 5
4x - 3x = 5 - 8
x = -3
Therefore,
The value of x is -3.

Amara currently sells televisions for company A at a salary of $8000 plus a $110 commission for each television she sells. Company B offers her a position with a salary of $9440 plus a $20 commission for each television she sells. How many televisions would Amara need to sell for the options to be equal?
Answer:
16
Step-by-step explanation:
If Amara sells X TV's then
For company A the earnings will be 8000+110x
For Company B the earnings will be 9440+20x
How many televisions would Amara need to sell for the options to be equal?
We find the value of X by equating both equations
8000+110x=9440+20x
110x-20x=9440-8000
90x=1440
x=16
Amara need to sell 16 TV's for the options to be equal

9514 1404 393
Answer:
48
Step-by-step explanation:
The Pythagorean theorem tells you the square of the hypotenuse (longest side) is the sum of the squares of the other two sides. Let x represent the unknown side.
73² = x² +55²
5329 = x² +3025 . . . evaluate the squares
2304 = x² . . . . . . . . . subtract 3025 from both sides
48 = x . . . . . . . . . . . . take the square root of both sides
The exact length of the third side is 48.
What is the equation of the line in slope-intercept form?
Answer:
y=9x
Step-by-step explanation:
What is the equation in the standard form of a parabola with a vertex of (4,2) that passes through (2, 14)?
9514 1404 393
Answer:
y = 3x^2 -24x +50
Step-by-step explanation:
The vertex form is ...
y = a(x -4)^2 +2
where 'a' is chosen to make the curve pass through the given point.
14 = a(2 -4)^2 +2 . . . . substitute the given point
14 = 4a +2 . . . simplify
12 = 4a . . . . . subtract 2
3 = a . . . . . . . divide by 4
Then the standard form is the expansion of the vertex form:
y = 3(x -4)^2 +2 = 3(x^2 -8x +16) +2
y = 3x^2 -24x +50
