The table shows values for functions f(x) and g(x)

Pls help I need it done tonight

Ksenya-84 [330]

Answer:

ABD= 58

BDC= 32

Step-by-step explanation:

complementary = 2 angles equal 90 degrees.

8y+2=90

Subtract 2 both sides.

8y=88

y=11

That's not all, put y into the equations.

ABD

5(11)+3

Multiply

55+3=58

BDC

3(11)-1

MULTIPLY

33-1

SUBTRACT

32

The height in feet, h, of a model rocket t seconds after launch is given by the equation h(t) = 3+70t - 16t^2. The average rate

andriy [413]

Answer:

The average rate of change

$\frac{dh}{d t} = 70 (1) - 16(2t)$

At t = 1

$\frac{dh}{d t} = 70 (1) - 16(2t) = 38$

at t=3

Step-by-step explanation:

Step(I):-

The given function h(t) = 3+70t - 16t²

$\frac{dh}{d t} = 70 (1) - 16(2t)$

The $\frac{dh}{d t} = 70 (1) - 16(2t) =0$

70 - 32 t = 0

⇒ 70 = 32 t

⇒ $t = \frac{70}{32} = \frac{35}{16}$

Step(ii):-

The average rate of change in h(t) between t = 1 second and t = 3 second

$\frac{dh}{d t} = 70 (1) - 16(2t)$

At t = 1

$\frac{dh}{d t} = 70 (1) - 16(2t) = 38$

At t = 3

Fancy goldfish x cost $3 each and common goldfish y cost $1 each.Graph the function y=20-3x to determine how many of each type o

aniked [119]

The pairs of goldfish Tasha can buy for $20 are $(0,20), (1,17), (2,14),$

$(3,11),(4,8),(5,5),and (6,2)$

Step-by-step explanation:

To find the how many type of goldfish that Tasha can buy for $20 is the set of positive ordered pairs.

Let x denote the number of fancy goldfish.

Let y denote the number of common goldfish.

To find how much goldfish can Tasha buy for $20 is to substitute the value for x in the equation $y=20-3x$

Now, substituting $x=0$ in $y=20-3x$ , we get,

$y=20$

The ordered pair is $(0,20)$

Similarly, substituting $x=1$ ,

$y=20-3(1)\\y=20-3\\y=17$

For $x=2$ ,

$y=20-6\\y=14$

For $x=3$ ,

$y=20-9\\y=11$

For $x=4$ ,

$y=20-12\\y=8$

For $x=5$ ,

$y=20-15\\y=15$

For $x=6$ ,

$y=20-18\\y=2$

Thus, the pairs of goldfish Tasha can buy for $20 are $(0,20), (1,17), (2,14),$ $(3,11),(4,8),(5,5),and (6,2)$
