Answer:
Step-by-step explanation:
1/2 + 1 1/16 + 3/8 = ?

A deep sea diver dives 26 feet from the surface of the ocean. He then ascends 7 feet. What interger represents the divers present location in the sea?
Answers
Answer:
-19
Step-by-step explanation:
Previous position in sea + change in position= current position
-26+7= -19
Hope this helps! :)
Answer:
It is -19
Step-by-step explanation:
Well, you would do this -26 + 7 because the diver dove 26 feet BELOW sea level, which is also -26. He then ascends 7 feet, which means he is coming UP. So -26 + 7 = -19.
The path of a skateboarder can be modeled by the equation (x – 3)2 = –4(y – 9), where distance is in feet and air resistance is insignificant. If the skateboarder makes a jump from a ramp at x = 0, what is her maximum height and how far is she horizontally from the end of the ramp when she lands?
Answers
Answer:
The correct answer would be: "Maximum height 9 feet; horizontal distance 9 feet".
Step-by-step explanation:
I know this not only because I already took the test, BUT by graphing the equation (you can use graphing apps) it'll give you the answer.
Her maximum height is 9 feet & she is horizontally 9 feet from the end of the ramp when she lands.
What is skateboarders maximum height ?
The path of the skateboarder can be modelled by the equation,
(x-3)² = -4(y-9)
Now, from the equation, solving y,
(x-3)² = -4(y-9)
⇒ y-9 = -[tex]\frac{1}{4}[/tex](x-3)²
⇒ y = -[tex]\frac{1}{4}[/tex](x-3)² + 9
∴ Maximum height is 9 feet.
How far is she horizontally from end of ramp ?We have to take y = 0,
Now, -[tex]\frac{1}{4}[/tex](x-3)² + 9 = 0
⇒ -(x²-6x+9)+36 = 0
⇒ -x²+6x-9+36 = 0
⇒ x²-6x-27 = 0
⇒ x²-9x+3x-27 = 0
⇒ (x-9)(x+3) = 0
⇒ x = 9 or x = -3
Neglecting the negative value we get, x = 9
So, Her horizontal distance from end of the ramp is 9 feet.

Step-by-step explanation:
N₁ = 6
N(n+1) = 6*(Nn -4 )
N₍₁₊₁₎= 6* (N₁ - 4)
N₂ = 6 *(6-4) = 6*2
N₂ = 12

Answer:
x = (y +2)/3
Step-by-step explanation:
The flowchart is trying to help you see that you "undo" what is done to x, in reverse order.
x is first multiplied by 3, then -2 is added.
First, we want to undo the addition of -2, so we add the opposite of that to y:
y = 3x -2 ⇒ y +2 = 3x
Then we want to undo the multiplication by 3, so we divide by 3:
y +2 = 3x ⇒ (y +2)/3 = x
The solution for x is ...
x = (y +2)/3

In your diagram, each box has the inverse operation of the one in the box above it. The inverse of subtracting 2 is adding 2. The inverse of multiplying by 3 is dividing by 3. The arrows connecting the boxes are intended to show you that these inverse operations occur in the reverse order of the original operations, as we described above. (The small box at bottom center might contain "3x".)

Evaluate each function for the given input values. For f (x)=2/3x+ 3, find f (x) when x= 9 and when x=-3
Answers
Answer:
Step-by-step explanation:
f(x) = 2/3 x + 3
x = 9
f(9) = 2/3 * 9 + 3 Divide 9 by 3
f(9) = 2 * 3 + 3 Combine 2 * 3
f(9) = 6 + 3 Combine
f(9) = 9 The answer is just a coincidence. The answer for the next one shouldn't be - 3
f(-3) = 2/3 *(-3) + 3 Divide 3 into - 3
f(-3) = 2*(-1) + 3
f(-3) = -2 + 3
f(-3) = 1

A street sign is in the shape of an isosceles triangle that has a base of 6.5 inches bigger than either of the equal sides. If the perimeter of the triangle is 65 inches, what is the length of the equal sides?
Answers
Answer:
19.5
Step-by-step explanation:
side is 6.5 bigger, so minus the 6.5 from the total perimeter of 65 and divide by 3.
65- 6.5 = 58.5
58.5 ÷ 3 = 19.5
equal sides are 19.5
longer side is 19.5 + 6.5
Answer:
19.5 inches
Step-by-step explanation:
You can interpret this problem as x + x + (x + 6.5)=65, with x being the length of the equal sides.
Simplified, this equation becomes 3x+6.5=65.
Solving, this becomes 3x+6.5-6.5=65-6.5 which comes out as 3x=58.5. Next, we divide this equation by 3 on both sides, which then comes out to x=19.5. Therefore, the length of equal sides are 19.5.
Check: There are two equal sides, so 19.5+19.5. Since the base is 6.5 inches bigger than either of the equal sides, the base is equal to 19.5+6.5=26. Adding these values all together comes out to 19.5+19.5+26=65.
