Answer:
x = 2, x = -5/2
Step-by-step explanation:
2x² + x - 10 = 0
(2x + 5)(x - 2) = 0
2x + 5 = 0
2x = -5
x = -5/2
x - 2 = 0
x = 2

determine the domain of the following graph
Answers
Answer:
[-5, 10) or you can write [tex]-5\le x < 10[/tex]
Step-by-step explanation:
The domain is the set of all values of x used in the function. Scan across the graph from left to right (much as you do when reading). The first point you find on the graph has an x-coordinate 5 (see the solid dot?). Then, as you continue reading across the graph, there are values of x used until you get to 10. The dot at x = 10 is open, not filled in. That indicates that the number x = 10 is NOT used by the function.
So the domain is all real numbers greater than or equal to -5 and less than 10.
[-5, 10) is called interval notation; a square bracket means the value next to it IS used by the function, a parenthesis means the value next to it is NOT used.
At the city triathlon, athletes bike 110 miles, run a 23.5 miles marathon, and swim. If the total distance of this triathlon is 135.7 miles, how far de the athletes swim?
Answers
Answer: 2.20 miles
Step-by-step explanation:
The triathlon involves the bike race, swimming and the marathon.
You are given the distance for the marathon, the biking and the total distance.
Total distance = Swimming + Marathon + Biking
135.7 = Swimming + 23.5 + 110
Swimming = 135.7 - 23.5 - 110
Swimming = 2.20 miles

This is solving quadratic functions by square roots btw
Answers
Multiply both sides by 4 to get rid of the four on the left.
3x^2 = 192
Divide both sides by 3
x^2 = 64
The square root 64 to get x
Remember there are two answers
x = 8 and x = -8
Answer:
x = 8
Explanation:
[tex]\frac{3x^2}{4} =48[/tex]
multiply both sides by 4: [tex]3x^2=192[/tex]
divide both sides by 3: [tex]x^2=64[/tex]
take the square root:

Ja’quan was told to go inside one afternoon while he was at summer camp. He heard thunder and saw flashes of lightning. Suddenly, small balls and chunks of ice were falling on the field. Ja’quan checked the thermometer, because he never saw ice fall in South Florida, and noticed that it was 77°F (or 25°C). How was ice able to fall even though the temperature was much warmer than freezing?
a) Ja’quan read the thermometer wrong
b) He must have observed hail falling from thunder clouds

Caterers made 272 cups of punch for a party. They will distribute the punch equally into 6 bowls. How many cups of punch will each bowl have? A. B. C. D.
Answers
Answer:
45.33 cups.
Step-by-step explanation:
272 divided by 6 gives this answer
The number of cups of punch each bowl will have is given by the equation A = 45.3 cups
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of cups of punch in each bowl be represented as A
Now , the equation will be
The total number of cups of punch = 272 cups
The number of bowls = 6 bowls
So , the number of cups of punch in each bowl A = total number of cups of punch / number of bowls
Substituting the values in the equation , we get
The number of cups of punch in each bowl A = 272/6
The number of cups of punch in each bowl A = 45.3 cups
Therefore , the value of A is 45.3 cups
Hence , the number of cups in each bowl is 45.3 cups

A solid circular cylinder has a base radius 5 cm and a height 12.5 cm. Find the approximate increase in the surface area of the cylinder when the radius of the base increases to 5.05
Answers
Answer:
19.72 cm²
Step-by-step explanation:
A solid circular cylinder has a base radius 5 cm and a height 12.5 cm.
The volume of cylinder is given by :
[tex]V=\pi r^2 h\\\\=3.14\times (5)^2\times 12.5\\\\=981.25\ cm^2[/tex]
When r = 5.05, new volum becomes,
[tex]V=\pi r^2 h\\\\=3.14\times (5.05)^2\times 12.5\\\\=1000.97\ cm^2[/tex]
Increase in area = 1000.97 - 981.25 = 19.72 cm²
So, the increase in surface area of the cylinder is equal to 19.72 cm².

State the slope and y-intercept for the graph of the equation -8x + y = -12.
Show your work!!
Answers
Answer:
Slope is 8 and Y-Intercept is -12
Step-by-step explanation:
Move the -8x over to the right side by adding it, You are now at
y=-12+8x
Move these around and you are now at
Y=8x-12
Answer:
Step-by-step explanation:
Remark
y must have a numerical coefficient of 1. This equation does. If it does not, then you must divide through by whatever is in front of the y.To read the slope, you must have x and its coefficient on opposite sides of the equal sign. So you get y = 8x - 12 when you add 8x to both sidesNext, the y intercept is found when x = 0y = 8x - 12y = 8(0) - 12y = - 12The y intercept is -12 or in point form (0, - 12)Answer
slope = 8
y intercept = - 12
