D (t)=16t□2+96t+112 where t represents time in seconds
Luda [366]
A.
the starting point is where t=0
d(0)=-16(0)^2+96(0)+112
D(0)=112
started from 112 feet


b. max height is vertex
for
y=ax^2+bx+c
the x value of the vertex is -b/2a

so
D(t)=-16t^2+96t+112
t value of vertex is -96/(2*-16)=3
it reaches after 3 seconds

C. simpliy evaluate D(t) for t=3
D(3)=-16(3)^2+96(3)+112
D(3)=-16(9)+288+112
D(3)=-144+400
D(3)=256
max height is 256ft

(HELP ASAP!!)
7nadin3 [17]

Answer:

1500

Step-by-step explanation:

24 month means 2 years ( N )

rate 15 pcpa ( R )

amount is 5000 ( P )

so by formula

interest = P×N×R/100

so ( I ) = 5000×2×15/100

so( I ) = 50×2×15 ....... ( here 100 ( 2 zero ) and 5000.( 2 zero ) got canceled

so ( I ) = 50×2×15

so ( I ) = 100×15

so ( I ) = 1500

What is the equation? Pls show your work.
Semmy [17]

Answer:

y=2x-2

Step-by-step explanation:

y=mx+b is point slope form.

let m= the slope

b=y intercept

the y intercept is -2

y=mx-2

then after finding the slope (2) put that in

y=2x-2

Determined to find the slope<br>(1 7K), and (-3,5K)​
Helga [31]

Answer: \dfrac{K}{2} .

Step-by-step explanation:

As we know ,

The slope of a line that passes through (x_1,y_1) and (x_2,y_2)  is given by :

\dfrac{y_2-y_1}{x_2-x_1}

The slope of a line that passes through (1 , 7K), and (-3,5K)​ =

\dfrac{5K-7K}{-3-1}\\\\=\dfrac{-2K}{-4}\\\\=\dfrac{K}{2}

Hence, the slope of the given line is \dfrac{K}{2} .
