Question 10 of 10

Mathematics
1 answer:
Aliun [14]3 years ago
7 0

Answer:

D. 28

Step-by-step explanation:

We are given the following polynomial function:

F(x) = x^2 - 2x - 7

Find F(-5).

This is the value of F for which x = -5. So

F(-5) = (-5)^2 - 2(-5) - 7 = 25 + 10 - 7 = 28

28, which means that the correct answer is given by option D.

The altitude of a triangle is increasing at a rate of 1 cm/ min while the area of the triangle is increasing at a rate of 2 cm2
serg [7]
Ya, calculus and related rates, such fun!




everything is changing with respect to t

altitude rate will be dh/dt and that is 1cm/min
dh/dt=1cm/min

area will be da/dt which is increasing at 2cm²/min
da/dt=2cm²/min

base=db/dt

alright

area=1/2bh
take dervitivie of both sides
da/dt=1/2((db/dt)(h)+(dh/dt)(b))
solve for db/dt
distribute
da/dt=1/2(db/dt)(h)+1/2(dh/dt)(b)
move
da/dt-1/2(dh/dt)(b)=1/2(db/dt)(h)
times 2 both sides
2da/dt-(dh/dt)(b)=(db/dt)(h)
divide by h
(2da/dt-(dh/dt)(b))/h=db/dt

ok
we know
height=10
area=100
so
a=1/2bh
100=1/2b10
100=5b
20=b

so
h=10
b=20
da/dt=2cm²/min
dh/dt=1cm/min

therefor
(2(2cm²/min)-(1cm/min)(20cm))/10cm=db/dt
(4cm²/min-20cm²/min)/10cm=db/dt
(-16cm²/min)/10cm=db/dt
-1.6cm/min=db/dt

the base is decreasing at 1.6cm/min

What is the quotient (x3 + 8) ÷ (x + 2)? x2 + 2x + 4 x2 – 2x + 4 x2 + 4 x2 – 4
MissTica

Answer:

x^2-2x+4

Step-by-step explanation:

The given expression is

\frac{x^3+8}{x+2}

Recall and use the following property to factor the numerator;

a^3+b^3=(a+b)(a^2-ab+b^2)

\frac{x^3+2^3}{x+2}=\frac{(x+2)(x^2-2x+2^2)}{(x+2)}

This will give us;

\frac{x^3+2^3}{x+2}=\frac{(x+2)(x^2-2x+4)}{(x+2)}

Simplify;

\frac{x^3+2^3}{x+2}=x^2-2x+4
