The Force equals to Mass times acceleration.
Thus, we now know that the mass of the object is 4 (unit of mass). Hence 8/2=4.
So, 3 times 2 equals to 6 N.
Am I correct?
What values of b will cause 8x^2 x bx + 2 = 0 to have one real solution?
=======================================================
Explanation:
I'm assuming you meant to type 8x^2 + bx + 2 = 0
Compare this to ax^2 + bx + c = 0
We have a = 8, b = unknown, c = 2.
We'll use the discriminant formula which is D = b^2 - 4ac to find that
D = b^2 - 4ac
D = b^2 - 4*8*2
D = b^2 - 64
Since we want one real solution, we set the discriminant equal to zero.
D = b^2 - 64
0 = b^2 - 64
64 = b^2
b^2 = 64
b = sqrt(64) or b = -sqrt(8)
b = 8 or b = -8
So the equation 8x^2 + 8x + 2 = 0 has one solution. So does the equation 8x^2-8x+2 = 0

What fraction does Point A on the number line below represent?
A horizontal number line is shown from negative 1 to 0 to positive 1.There are tick marks to show increments of 1 over 8. Only the whole numbers are labeled. Plot Point A at the third tick mark to the right of 0.
(10 point)
a
fraction 3 over 8
b
fraction negative 3 over 8
c
fraction 6 over 8
d
fraction negative 6 over 8
Answer:
It should be A
Step-by-step explanation:
Since the number is positive and the tick marks divide the whole numbers by 8ths and you need to plot the dot 3 ticks to the right of zero it would be 3 over 8.

Answer:
The answer would be 22/12 or 1 and 11/12
Step-by-step explanation:
1/2+2/3+3/4
First get common denominators so you have a denominator of 12 so 6/12+8/12+9/12
Add those together and you get 23/12 but you have to subtract one because that's what the problem says so you get 22/12

Javier was making a cake from scratch. The recipe he is using makes enough cake to
serve 15 people. Javier wants to triple (X 3) the recipe. The ingredients are:
2. If Javier triples the recipe, how many people will he be able to serve?
• 2 cups all-purpose flour
• 2 cups sugar
• 1 teaspoon baking soda
• 1/2 teaspoon salt
• 1/2 teaspoon ground cinnamon
• 1 can (12 ounces) cola
1 cup butter, cubed
1/4 cup baking cocoa
• 2 large eggs, room temperature I
1/2 cup buttermilk
• 1 teaspoon vanilla extract
.
Answer:
45
Step-by-step explanation:
it we triple the recipe then we well have to times the people by 3 so 15x3=45
so 45 is your answer
Frederick evaluates the numerical expression [(53.7 + 37.2) - (3 3 + 3.8)] - 8.6 and records the answer as 51.5. Lana evaluates the numerical expression 53.7 + 37.2 - 3 3 + 3.8 - 8.6 and records the answer as 59.1. The expressions have the same numbers and operations. Explain how Frederick and Lana can both be correct.
answer this to prove your worth
Both people can be correct because of a little something called PEMDAS or the OOO (order of operations). In the first problem, the equation includes brackets and parentheses, doing 53.7+37.2 THEN 33+3.8 THEN subtracting them THEN subtracting 8.6 from that number, instead of doing 53.7+37.2 THEN subtracting 33 THEN adding 3.8 THEN subtracting 8.6. Doing certain parts of the equation first, dicated by the parentheses/brackets/braces, can change the final answer. The second expression has you going in order one by one, while the first has you doing groups of the equation at a time (neither are wrong or bad).

Trevor ran 2.3 miles on Monday and then ran some more on Tuesday, he had run a total of 5.55 miles for the week. How much did he run on Tuesday?
Answer:
He ran 3.25 on Tuesday
Step-by-step explanation:
The answer is 3.25 because 5.55 minus 2.3 is 3.25.
Answer:
3.25 miles
Step-by-step explanation:
Let's use x as a placeholder for the number you don't know yet.
2.3+x=5.55
To get the x by itself, we need to subtract 2.3. Remember, whatever we do to one side we have to do to the other side.
x=5.55-2.3
Now we must subtract 2.3 from 5.55.
5.55-2.3=3.25
Now we know:
x=3.25
Since the question asks for the answer in miles, we can say that Trevor ran 3.25 miles on Tuesday.
