Mark dropped an object from a bridge 400 feet above the ground level with an initial velocity of 0. He knows that the gravitational pull of the earth is about 16 feet per second squared. wants to find how many seconds,t, it will take the object to hit the ground. Match each expression with the correct equation that models this situation or solution.
Answer:
The first listed equation is the correct equation to solve
The correct answer is: t = 5 seconds
Step-by-step explanation:
Let me mention first that there is an error in the statement that the gravitational pull of the Earth is 16 ft/s^2. It is in fact 32 ft/s^2, and the actual equation uses half of the acceleration multiplied by the square of the variable time, so it gives as final expression :
[tex]y(t)=-16\,t^2+ 0 \,t +400[/tex]
and we want to find the value/s for "t" that make this equation equal zero (when it reaches the ground and the object just touches the ground. This makes the equation we want to solve:
[tex]0=-16\,t^2+ 0 \,t +400\\16\,t^2+0\,t -400=0[/tex]
which solving for "t" becomes:
[tex]16\,t^2-400 =0\\16\,t^2=400\\t^2=\frac{400}{16} \\t^2=25\\t= +/- 5\,\,sec[/tex]
So we adopt the positive answer (positive time) since the negative value has no physical meaning for this problem.
That is: t = 5 seconds
correct equation: -16t^2 + 0t + 400 = 0
solution: 5 seconds

Find the area of a circle with diameter 10cm use the value 3.14
Answer:
78.5 cm
Step-by-step explanation:
The area of a circle is represented by A = πr². Since we are replacing the value of pi(π) with 3.14, and the diameter is 10, meaning the radius(r) is 5, we can plug both values into the equation, to get A = 3.14(5^2). This simplifies to 78.5.
Answer:
78.5 cm^2[tex]solution \\ diameter = 10 \: cm \\ radius = \frac{10}{2} = 5 \: cm \\ area \: of \: circle = \pi \: {r}^{2} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 3.14 \times {5}^{2} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 3.14 \times 5 \times 5 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 3.14 \times 25 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 78.5 {cm}^{2} [/tex]

In 2010, Rafik bought a house. In 2015, Rafik sold the house to Bianca. He made a 20% profit on the sale. In 2019, Bianca sold the house for £193800. She made a 5% loss. Work out how much Rafik paid for the house in 2010.
9514 1404 393
Answer:
£170,000
Step-by-step explanation:
Bianca bought the house for 1 +20% = 1.2 times Rafik's purchase price. She sold it for 1 -5% = 0.95 times what she bought it for. So, we have ...
(Rafik's purchase price)×1.2×0.95 = £193800
Rafik's purchase price = £193,800/(1.2×0.95) = £170,000
Rafik bought the house for £170,000.

ANSWER QUICKLY!!! Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2, and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.
(QUESTION!!!)--->Graph the function. On the graph, make sure to label the intercepts. You may graph your equation by hand on a piece of paper and scan your work or you may use graphing technology.
1. 2x + 3y = 1470
3y = -2x + 1470
y = -2/3x + 490 <== slope intercept form
==================
2. y = -2/3x + 490....slope = -2/3.....y int = (0,490)
to graph, start at (0,490)....since the slope is -2/3, we will go down 2 spaces, then to the right 3 spaces, then down 2 spaces, and to the right 3 spaces. It helps to find the x int which can be found by subbing in 0 for y into the equation and finding x. So ur x int is (735,0)...this is where ur line should cross the x axis.
===================
3. function notation : f(x) = -2/3x + 490...not sure how to explain the meaning...sorry
===================
4. graph the function....it will be the same line as the graph I explained before...y = -2/3x + 490
y int = (0,490)
x int = (735,0)
===================
5. original : new :
2x + 3y = 1470 2x + 3y = 1593
3y = -2x + 1470 3y = -2x + 1593
y = -2/3x + 490 y = -2/3x + 531
similarities : Both of these equations will have the same slope, which is -2/3. Both lines are descending. Both lines are parallel to each other.
differences : These lines will have different x and y intercepts
y = -2/3x + 490 : y int = (0,490), x int = (735,0)
y = -2/3x + 531 : y int = (0,531), x int = (796.5,0)
======================
6. pick 2 points on the line.....(0,300) and (450,0)
find the slope using the slope formula : slope = (y2 - y1) / (x2 - x1)
(0,300)....x1 = 0 and y1 = 300
(450,0)...x2 = 450 and y2 = 0
now we sub and find the slope
slope = (0 - 300) / (450 - 0) = -300/450 reduces to -2/3
now we use y = mx + b
slope(m) = -2/3
use either of ur points...(450,0)...x = 450 and y = 0
now sub and find b, the y int
0 = -2/3(450) + b
0 = - 300 + b
300 = b
so ur equation is : y = -2/3x + 300....or 2x + 3y = 900

Clara is building a triangular garden. She wants the length of the longest side to be three more than twice as long as the length of the shortest side, and the third side will be twelve feet long.
Answer:
3s+15
Step-by-step explanation:
let 's' be the length of the shortest side
-> twice as long as the length of the shortest side =2s
->length of the longest side to be three more than twice as long as the length of the shortest side = 2s + 3
-> the third side= 12 feet
p = s + 12 + 2s+3
p= 3s+15

A garden is in the shape of a rectangle 85 m by 50 m.
Flowers are grown in 32% of the garden.
The rest of the garden is grass.
Work out the area of the garden that is grass.
50 m
Answer
2890
Step-by-step explanation:
2,890 meters^2 is grass
Step-by-step explanation:
First find the area of the garden
Area of a rectangle can be found using:
a=lw
a=85*50
a=4,250 meters^2
We know that 32% of the area is flowers, so we can multiply 32% and 4250
32%*4250
Convert 32% to a decimal by dividing by 100
32%/100=0.32
0.32*4250=1360
So, 1360 meters^2 is flowers.
The rest must be grass, so we can find the difference between the total area and the flowers
4250-1360=2890

In circle P, diameter QS measures 20 centimeters. Circle P is shown. Line segment Q S is a diameter. Line segment R P is a radius. Angle R P S is 123 degrees. What is the approximate length of arc QR? Round to the nearest tenth of a centimeter. 9.9 centimeters 19.9 centimeters 21.5 centimeters 43.0 centimeters
Answer:
Length of arc QR is [tex]\approx[/tex] 9.9 cm
Step-by-step explanation:
Given that circle P, i.e. center is point P.
QS is diameter with length 20 cm.
Given that RP is the radius with
[tex]\angle RPS = 123^\circ[/tex]
To find length of arc QR = ?
Solution:
Arc QR subtends the [tex]\angle QPR[/tex] on center P.
So, we need to find the angle [tex]\angle QPR[/tex] to find the length of arc QR.
QS is the diameter so [tex]\angle QPS = 180^\circ[/tex]
[tex]\angle QPS = 180^\circ = \angle QPR +\angle RPS\\\Rightarrow 180^\circ = \angle QPR +123^\circ\\\Rightarrow \angle QPR = 57^\circ[/tex]
Converting in radians,
[tex]\angle QPR = 57^\circ \times \dfrac{\pi}{180} = 0.99\ radians[/tex]
Using the formula for length of arc:
[tex]l = \theta \times R[/tex]
Where [tex]\theta[/tex] is the angle subtended by the arc on center.
R is the radius of circle.
Here,
[tex]\theta = 0.99\ radians\\R = 10\ cm[/tex]
[tex]l = 0.99 \times 10\\l = 9.9\ cm[/tex]
Length of arc QR is [tex]\approx[/tex] 9.9 cm
Answer:
9.9 cm
Step-by-step explanation:
