after swimming 60 feet below the surface of the water, a whale swims up 30 feet. use a number line to help you create an equation that shows the new location of the whale in relation to the water's surface.
ANSWER:
A. The equation is -60 + 30 = 30. The whale is 30 feet below the waters surface.
B. The equation is -60 + (-30) = -90. The whale is 90 feet below the waters surface.
C. The equation is -60 + 30 = -90. The whale is 90 feet below the waters surface
D. The equation is -60 + (-30) = -30. The whale is 30 feet below the waters surface.
Answers
Answer:
First, in standard notation, we must define our zero.
In this case, would make sense to define the zero in the surface of the water.
(below is a number line so you can see the process to think this)
Then if the whale is swimming 60ft bellow the surface of the water, then the first position of the whale is:
-60
Now the whale goes up 30ft, then the new position of the whale is:
-60ft + 30ft = -30ft.
The correct option is A:
The equation is -60 + 30 = -30. The whale is 30 feet below the water's surface.
(you wrote that the equation was equal to +30 instead of -30 in the option A, i supposed that it was a typo)
Answer:
I belive the answer is A.
Step-by-step explanation:
A projectile is launched into the air. The function h(t) = –16t2 + 32t + 128 gives the height, h, in feet, of the projectile t seconds after it is launched. After how many seconds will the projectile land back on the ground?
The projectile will land after ______ seconds
Answers
Answer:
t = 4 seconds
Step-by-step explanation:
The height of the projectile after it is launched is given by the function :
[tex]h(t)=-16t^2+32t+128[/tex]
t is time in seconds
We need to find after how many seconds will the projectile land back on the ground. When it land, h(t)=0
So,
[tex]-16t^2+32t+128=0[/tex]
The above is a quadratic equation. It can be solved by the formula as follows :
[tex]t=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]
Here, a = -16, b = 32 and c = 128
[tex]t=\dfrac{-32\pm \sqrt{(32)^2-4\times (-16)(128)} }{2\times (-16)}\\\\t=\dfrac{-32+ \sqrt{(32)^2-4\times (-16)(128)} }{2\times (-16)}, \dfrac{-32\- \sqrt{(32)^2-4\times (-16)(128)} }{2\times (-16)}\\\\t=-2\ s\ \text{and}\ 4\ s[/tex]
Neglecting negative value, the projectile will land after 4 seconds.
Write the equation of a line that is parallel to y =1/2x + 9 and goes through the point (-2,2)
Answers
Answer:
y = 1/2x + 3
Step-by-step explanation:
The slope of a parallel line is the same as the original.
Find the new y-intercept.
y = 1/2x + b
2 = 1/2(-2) + b
2 = -1 + b
3 = b
y = 1/2x + 3

What is the domain of the relation?

Oc. { -2,-1, 0, 1, 2, 3}
Ob.{-2, 0, 1,3}
Od. {0, 1, 2, 3}
Answers
Answer:
(03.01) The domain of a relation is the output (y) values of the relation the input (x) values of the relation a set of points that pair input values with output values x and y values written in the form (x, y)
{-2, -1, 0, 1, 2, 3} representing the domain of the relation.
What is a function?A relation is a function if it has only One y-value for each x-value.
To determine the domain of a relation, we need to identify all possible values for the input or independent variable.
In this case, without any further information, we can look for the set of numbers provided in the answer choices and determine which set includes all possible values for the input.
Looking at the given answer choices:
A. {-1, 0, 1, 3}
B. {-2, 0, 1, 3}
C. {-2, -1, 0, 1, 2, 3}
D. {0, 1, 2, 3}
Since there is no specific information or restrictions mentioned, the most inclusive set that covers all possible values for the input variable is {-2, -1, 0, 1, 2, 3}.
Therefore, {-2, -1, 0, 1, 2, 3}, representing the domain of the relation.

What is (n+8) + (n-12)
Answers
Answer:
n = 2
Step-by-step explanation:
Simplifying
(n + 8) + (n + -12) = 0
Reorder the terms:
(8 + n) + (n + -12) = 0
Remove parenthesis around (8 + n)
8 + n + (n + -12) = 0
Reorder the terms:
8 + n + (-12 + n) = 0
Remove parenthesis around (-12 + n)
8 + n + -12 + n = 0
Reorder the terms:
8 + -12 + n + n = 0
Combine like terms: 8 + -12 = -4
-4 + n + n = 0
Combine like terms: n + n = 2n
-4 + 2n = 0
Solving
-4 + 2n = 0
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + 2n = 0 + 4
Combine like terms: -4 + 4 = 0
0 + 2n = 0 + 4
2n = 0 + 4
Combine like terms: 0 + 4 = 4
2n = 4
Divide each side by '2'.
n = 2
Simplifying
n = 2

M is the midpoint of LN. If LM = 3x and MN = x + 8, what is MN?
Answers
Answer:
12
Step-by-step explanation:
Since M is a midpoint of LN, we can see 3x equal to x+8. Remove 1 x to get 2x=8. Solve for x to get x=4. Note that this is not the end to your problem. They asked for the length of MN, not the value of x. Plugging x into MN give you 4+8, which is 12.
(If you need to show work, here it is)
3x=x+8
2x=8
x=4
MN=x+8
MN=4+8
MN=12
The basketball team sold pizzas for a fundraiser. They sold large pizzas for $15.00 and medium pizzas for $12.00. If the basketball team sold 96 pizza all together and made $1356, how many of each type of pizza did they sell?
Answers
Answer:
93 large, 3 medium
the first thing you gotta do is find the least amount of the smaller number that you can take away until it becomes a multiple of the largest number.
1356-12(1)
1344-12(2)
1332-12(3)
1320 12 factored into 1356 3 times before we reached a multiple of 15 so we subtract 3 from the total number of pizza sold and we have 93 large pizzas and 3 medium pizzas
