A hiker stands on a small hill and tosses a stone. The stone then follows a path with height h above the ground at time t. The function
h(t) = - 16t2 + 16x + 32 models the stone's path. How long does it take the stone to reach its maximum height?
Answer:
At time t=0.5, the stone reaches a maximum height of h= 35.
Step-by-step explanation:
A quadratic function or function of the second degree is a polynomial function defined by:
f(x)=a*x² + b*x +c
The maximums and minimums of a function are the largest (maximum) or smallest (minimum) values of a function.
The vertex of the function is a point that is part of the parabola or quadratic function that coincides with the maximum or minimum. When a> 0, the vertex of the parabola is at the bottom of it, being a minimum (that is, the parabola opens "upward"), and when a <0 the vertex is at the top , being a maximum (that is, the parable opens "downward").
h represents the value of its abscissa (value of x).
k represents the value of its ordinate (value of f (x)).
The value of h can be calculated with the formula [tex]h=-\frac{b}{2*a}[/tex]
The value of k must be obtained by substituting the value of h in the function f(x)=a*x² + b*x +c
In this case: a=-16, b=16 and c=32. As a <0 the vertex is at the top , being a maximum. So:
[tex]h=-\frac{16}{2*(-16)}=0.5[/tex]
Substituting the value of h in the function f(x)=-16*x² + 16*x +32 you get:
f(0.5)=-16*0.5² + 16*0.5 +32
f(0.5)= 35
At time t=0.5, the stone reaches a maximum height of h= 35.
Andrew cut a rectangular piece of wood along a straight line, as shown below. K110° Andrew calculated that x = 70°. Which of the following statements justifies Andrew's calculations? A Vertical angles are congruent. B. Altemate exterior angles are congruent. C. Consecutive interior angles are supplementary. D. Adjacent angles formed by perpendicular lines are complementary, Ο Α B C D PLEASEEEEEE HELP ME FAST !!
Answer:
C. Consecutive interior angles are supplementaryStep-by-step explanation:
Andrew calculated it correctly
Angles 110 and x are supplementary as consecutive interior angles
110 + x = 180x = 180 - 110x = 70Correct choice is C

Answer:
3[tex]\sqrt{3}[/tex] and [tex]\sqrt{7}[/tex]
Step-by-step explanation:
Simplifying surds is similar to collecting like terms in algebra.
If the surds have the same value then collect them by adding/ subtracting their coefficients.
(a)
[tex]\sqrt{3}[/tex] (7 - 2 + 1 - 3)
= [tex]\sqrt{3}[/tex] (3)
= 3[tex]\sqrt{3}[/tex]
(b)
[tex]\sqrt{7}[/tex] (5 + 4 - 8)
= [tex]\sqrt{7}[/tex] (1)
= [tex]\sqrt{7}[/tex]

The scale factor from a small triangle ABC to a large
triangle XYZ is 4. How many times larger will the
perimeter of triangle XYZ be than the perimeter of
triangle ABC?
9514 1404 393
Answer:
c 4 times
Step-by-step explanation:
If the side lengths of the original triangle are AB, BC, and CA, then those of the dilated triangle are 4AB, 4BC, 4CA.
The sums of these are the perimeters.
P = AB +BC +CA
perimeter of XYZ = 4AB +4BC +4CA = 4(AB +BC +CA) = 4P
The perimeter of XYZ is 4 times the perimeter of ABC.

Eric made a scale drawing of the middle school. The scale he used was 1inch=5feet. If the gym is 30 inches by 20 inches in the drawing, what is the acual length and width of the gym.
Answer: 150 feet : 100 feet
Step-by-step explanation:
From the question, we are informed that the scale used by Eric was 1inch=5feet.
If the gym is 30 inches by 20 inches in the drawing, the acual length and width of the gym would be:
Length = 30 inches = 30 × 5 feet = 150 feet
Width = 20 inches = 20 × 5 feet = 100 feet
Therefore, the acual length and width of the gym would be 150 feet by 100 feet
Answer:
Answer: 150 feet : 100 feet
Step-by-step explanation:
From the question, we are informed that the scale used by Eric was 1inch=5feet.
If the gym is 30 inches by 20 inches in the drawing, the actual length and width of the gym would be:
Length = 30 inches = 30 × 5 feet = 150 feet
Width = 20 inches = 20 × 5 feet = 100 feet

Option 1: $10.00 every day
Option 2: $3.00 on the first day, $3.50 on the second, $4.00 on the third, and so on, increasing by $0.50 per day.
Option 3: $0.01 on the first day, $0.02 on the second, $0.04 on the third, and so on, doubling each day.
Option 1: ($10.00 per day) :
#1 (Is this option Arithmetic, Geometric, or neither?)
#2 (Write a formula to find how much you would make on any day.)
Option 2 : (increases by $0.50 per day, day 1: $3.00)
#1 : Is this option Arithmetic, Geometric, or neither?
#2: Write a formula to find how much you would make on any day.
Option 3: (doubles each day, day 1: $0.01)
#1 : Is this option Arithmetic, Geometric, or neither?
#2: Write a formula to find how much you would make on any day.
Answer:
Option 1:
Arithmetic
f(x)=10+10xd
Option 2:
Neither
f(x)=3.00+0.50d
Option 3:
Geometric
f(x)=0.01(2)^x
Step-by-step explanation:
An arithmetic equation is one that increases by the same amount every day, a constant, straight rate. Geometric increases by the same amount everyday, doubling every day is an example of this, its linear, and is a constant rate of change.
f(x)=10+10xd means the initial 10 plus 10 every day, the d= day, so if you want to calculate a certain day, such as day 10 you replace d with the day number
f(x)=10+10x10= 110
f(x)=3.00+0.50d means initial 3.00 dollars adding 0.50 each day that passes, again, replace the d with the day number you are on.
f(x)=3.00+0.50 x 10= 8
f(x)=0.01(2)^x
the 0.01 is our starting number, the (2) represents the doubling every day, the x represents the day, and is squared.
f(x)=0.01(2)^10 = 10.24

Answer:
Irrational numbers cannot be written as a fraction, or the ratio of two whole numbers.
You would have to find a GCF (greatest common factor) and multiply it out of the radical.
ex.
[tex]\sqrt{6}[/tex] = 2 x 2 x 2
when you have to multiplier numbers then you can combine two of them to take outside the radical, meaning 2x2x2
2[tex]\sqrt{2\\}[/tex]
so [tex]\sqrt{6}[/tex] would be closest to the positive 2 on the number line and 2 notches.
[tex]\sqrt{11}[/tex]
is an irrational number, so it might fall into 3.3 if turned into a decimal.

A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 2,260 ft Determine the flag's width and length if the length is 290 ft greater than the width.
Answer:
length= 710 width= 420
Step-by-step explanation:
As we consider a rectangle we can replace "length" with l and "width" with w so that the perimeter will be:
2l+2w= 2260
With the length as:
l= w+290
The length, substituted into the perimeter is:
2(w+290)+2w=2260
Distribute:
4w+580=2260
Subtract:
4w=1680
Divide:
w=420
To find the length, take the width and add 290:
420+290=710
l=710
