Answer: 5.7s
Step-by-step explanation:
We are explicitly given the final velocity of 58.8m/s, and implicitly given the acceleration of 9.8m/s^2 due to gravity. We are also implicitly given the initial velocity of the pebble. The pebble was not thrown off the cliff, it simply fell off the cliff. Therefore the initial velocity is 0m/s. Using the first kinematic equation, you get:
[tex]v_f=v_i+at[/tex]
[tex]58.8=0+(9.8)t[/tex]
[tex]58.8=9.8t[/tex]
[tex]t=5.7s[/tex]

DEF is a dilation of ABC with center (0,0). What is the scale factor?
3
1/2
1/3
1/4
Answer:
that is a 1/3 dialation, becuase you can estimate the base of the bigger triangle to be around 12 and the base of the smaller triangle is 4, and that would be a fraction that is something like 4/12 which happens to be equal to 1/3.

The area of a square garden is
1/144 km ^2 . How long is each side?
Answer:
[tex]\frac{1}{12}[/tex] Km
Step-by-step explanation:
the area (A) of a square is calculated as
A = s² ( s is the side length )
here A = [tex]\frac{1}{144}[/tex] , then
s² = [tex]\frac{1}{144}[/tex] ( take square root of both sides )
s = [tex]\sqrt{\frac{1}{144} }[/tex] = [tex]\frac{1}{\sqrt{144} }[/tex] = [tex]\frac{1}{12}[/tex]
Answer:
side= 1/12 km = 0.083km
Step-by-step explanation:
The formula of area of a square is: A=side²
To get the length of each side, square root each side of the formula as shown below:
√A=√(side)²
√(1/144)=side
side= √(1/144) = 1/12 = 0.083km

What is the equation of the blue line?
Answer:
y=2x+3
Step-by-step explanation:
Because the y-intercept starts at 3 and it goes up by 2 and to the side 1 so it would be y = 2x +3
Answer: y = 2x + 3
Step-by-step explanation:
We will write the equation in slope-intercept form.
y = mx + b
The slope can be found with "rise over run" since we have clear points on the graph.
Start at (0, 3), count up 2 units, and count one unit to the right. This gives us a slope of positive 2.
Rise / run = 2 / 1 = 2
The "b" value is where the line hits the y-axis. It hits the y-axis at y-coordinate 3, so our y-intercept is positive 3.
Final equation:
y = 2x + 3
The rate (in mg carbon/m3/h) at which photosynthesis takes place for a species of phytoplankton is modeled by the function P = 110I I2 + I + 4 where I is the light intensity (measured in thousands of foot-candles). For what light intensity is P a maximum? I = thousand foot-candles
Using the vertex of a quadratic equation, it is found that P is at a maximum for l = -0.5 thousand foot-candles.
What is the vertex of a quadratic equation?A quadratic equation is modeled by:
[tex]y = ax^2 + bx + c[/tex]
The vertex is given by:
[tex](x_v, y_v)[/tex]
In which:
[tex]x_v = -\frac{b}{2a}[/tex]
[tex]y_v = -\frac{b^2 - 4ac}{4a}[/tex]
Considering the coefficient a, we have that:
If a < 0, the vertex is a maximum point.If a > 0, the vertex is a minimum point.In this problem, the function for P is given by:
[tex]P(l) = \frac{110l}{l^2 + l + 4}[/tex]
The function will be at a maximum when the denominator is at a minimum. The denominator is a quadratic function with coefficients a = 1, b = 1, c = 4, hence:
[tex]l_v = -\frac{b}{2a} = -\frac{1}{2} = -0.5[/tex]
P is at a maximum for l = -0.5 thousand foot-candles.

Is a triangle with sides 7 feet, 12 feet, and 14 feet a right, acute or obtuse triangle?
Answer:
Acute
Step-by-step explanation:
This should be an acute triangle because if this was a right angle, then the three sides should be figured out by the Pythagorean Theorem.
An obtuse angle wouldn't be right either, you need an angle to be over 90.
A cylinder has a radius of 19 millimeters. Its volume is 22,670.8 cubic millimeters. What is the height of the cylinder?
Answer:
19.99
Step-by-step explanation:
use the formula
[tex]\pi {r}^{2} h = v[/tex]
change it up so that you solve for height
[tex] \frac{v}{ {r}^{2} \times \pi } = h[/tex]
substitute values in and solve
Answer:
20.00 mm to the nearest hundredth.
Step-by-step explanation:
V = π r^2 h
22,670.8 = π * 19^2 * h
h = 22,670.8 / π * 19^2
= 22,670.8 / 1134.115
= 19.9899
An equilateral triangle is shown inside a square inside a regular pentagon inside a regular hexagon. Write an expression for the area of the shaded regions.
Answer:
the shaded area= area of the regular hexagon-the area of the regular pentagon+ the area of the square-the area of the equilateral triangle
Step-by-step explanation:
for the equation to be true we must first identify the shapes used.
the shapes used include
regular hexagonregular pentagonsquareequilateral trianglenow that we know the shapes we must find out which shapes are shaded
regular hexagon (shaded)regular pentagon (not shaded)square (shaded)equilateral triangle (not shaded)now we know which shapes are shaded we can now form the equation to find the area
i will turn the shapes into varibles so its easier on my brain and yours
area of the regular hexagon= harea of the regular pentagon= parea of the square= sarea of the equilateral triangle= tshaded area= Awe can know use the info gathered earlier to create the equation
shaded area = (area of the regular hexagon - area of the regular pentagon (the hexagon is shaded while the pentagon is not therefore you would subtract the area of the hexagon by the area of the pentagon))+(area of the square- area of the triangle( same reason as the hexagon and pentagon the triangle is not shaded therefore creating a gap in the square)
or in other words with the variables
A=( h-p )+( s-t )

A baseball bat costs $41. This is $9 more than four times the wholesale cost of the bat.Find the bat's wholesale cost.
We can find the bat's wholesale cost by working backwards -
Do $41 - 9 to get $32, then we can divide the 32 by the 4 to get $8.
Therefore, the wholesale cost of the bat is $8.
Happy to help!
Answer:
The bat's wholesale cost is $8
Step-by-step explanation:
You first have to subtract 9 from 41 as that will be 4 times the wholesale cost, which is $32. Then you have to divide 32 by 4, as we want to get the wholesale cost, not 4 times of the wholesale cost, and this would give us the wholesale cost, which is $8.
