If one of the roots of the equation x² - 4 + k = 0 exceeds the other by 2 , then find the roots and determine the value of k.
Answer:3
Step-by-step explanation:
Given
Quadratic equation is [tex]x^2-4+k=0[/tex]
if one root exceeds the other by two
suppose one of the roots is a, then the other is a+2
The Sum of roots is
[tex]=\dfrac{-\text{coefficient of x}}{\text{coefficient of }x^2}[/tex]
[tex]\therefore a+a+2=-\dfrac{-0}{1}\\\\\Rightarrow 2a+2=0\\\Rightarrow a=-1[/tex]
Product of roots
[tex]\Rightarrow (a)(a+2)=\dfrac{k-4}{1}\\\Rightarrow (-1)(1)=k-4\\\Rightarrow k=4-1=3[/tex]

Given the proportion a/b = 8/15, what ratio completes the equivalent proportion a/8=?
Answer:
a/8 = b/15
Step-by-step explanation:
a/b = 8/15 -- divide both side by 8 and multiple both side by b
a/8 = b/15
2) A circle has a diameter of 10 feet. What is the area of the circle, in square feet?
Answer:
Area = 78.5 square feet
Step-by-step explanation:
Formula for area of a circle: A = pi r^2 or area = pi times radius squared
So the diameter = 10 feet
And radius is half of the diameter so radius = 5 feet
A = pi x 5 squared
A = pi x 25
A = 78.5 square feet
Answer:
A = 78.5 [tex]ft^{2}[/tex]
Step-by-step explanation:
A = π[tex]r^{2}[/tex]
diameter = 10
radius is half of 10 = 5
A = 3.14 x [tex]5^{2}[/tex]
A = 3.14 x 25
A = 78.5 [tex]ft^{2}[/tex]
Let's play a game.... Find two numbers that multiply to
10 and add to 7.
Answer:
2 and 5
Step-by-step explanation:
five plus two equals 7
Answer:
5 & 2
Step-by-step explanation:
X + y = 7
X × y = 10
Solve with the help of trial & error method.
Factors of 10 - 1, 5, 2, 10
Let's take 5 as X & 2 as y.
X + y = 7 --- 5 + 2 = 7
X × y = 10 --- 5 × 2 = 10
Hence, the two numbers that multiply to 10 and add to 7 are 5 & 2
BC has endpoints at B(3, 8) and C(7,6). Find the midpoint M of BC.
Write the coordinates as decimals or integers.
Submit
Answer: (5, 7)
Step-by-step explanation: Midpoint formula is ((x1 + x2)/2, (y1+y2)/2) where (x1, y1) and (x2, y2) are points on a line. Thus
(3+7/2, 8+6/2) = (5, 7)
6.00+1.50(m)=26.25 find what m is
Answer:
13.5
Step-by-step explanation:
first let's subtract 6.00 from 6.00 and 26.25
26.25-6=20.25
1.50(m)=20.25
so we need to get rid of the 1.50
so 1.50m divided by 1.50=m
20.25÷1.50=13.5
m=13.5 hope this helps

Answer:
x = 10.43
Step-by-step explanation:
use tan:
⇒ tan = [tex]\frac{opposite}{adjacent}[/tex]
⇒ tan 41 = [tex]\frac{12}{x}[/tex]
tan of 41 is 0.869
⇒ 0.869 = [tex]\frac{12}{x}[/tex]
multiply each side by 12
⇒ 0.869 x 12 =[tex]\frac{12}{x}[/tex] x 12
x = 10.43
Answer:x = 10.43

The school band booster club runs a concession stand for home football games. They sell beverages for $1.50 and candy for $1.25. Their goal is to raise $375 for each game.
Write an equation that is a model for the different numbers of beverages and candy that can be sold to meet the goal.
1.25x + y = 375
x + y = 375
1.50x.- 1.25y = 375
1.50x +1.25y = 375
Answer:
1.50x + 1.25y = 375
Step-by-step explanation:
x = beverages
y = candy
1.50x + 1.25y = 375
The equation that can be used to model the different numbers of beverages and candy that can be sold to meet the goal is 1.50x+1.25y=375.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the number of beverages sold be x, while the number of candies sold is y.
Given that the selling price of a beverage is $1.50, while the selling price of candy is $1.25. Also, the total amount that is needed to be raised is $375. Therefore, the total cost can be written as,
[tex](\$1.50 \times x)+ (\$1.25 \times y) = \$375\\\\1.50x+1.25y=375[/tex]
Hence, the equation that can be used to model the different numbers of beverages and candy that can be sold to meet the goal is 1.50x+1.25y=375.

The length of packing a box is 24 in. the width is 1/2 of the length. The height is 3 1/2 inches more than the width. What is the volume of the packing box? HELPPPP
Answer:
4464in^3
Step-by-step explanation:
Length of Box = 24 in.
Width = 1/2 x Length = 1/2 x 24 = 12in.
Height = 3.5 + Width = 3.5 + 12 = 15.5 in.
Volume of box = Volume of Cube =
Length x Width x Height =
