Answer:

3

Step-by-step explanation:

You solve the inner first, then move to the outer.

Let's look at g(3) first. It is stated in the problem that g(3) = 2.

We then use this value for f(x). It is stated in the problem that f(2) = 3.

The answer is 3.

Jason and Eddy are traveling from Jacksonville to Miami, which is a distance of 382 miles. According to the American Automobile
wolverine [178]

Answer:

The value is  v =  49.23 \  mph

Step-by-step explanation:

From the question we are told that

  The  distance from Jacksonville to Miami is  d  =  382 miles

  The  time it take to travel from Jacksonville to Daytona is  t_1  = 1 \ hour\ and\ 54\ minutes = 1 + \frac{54}{60} =  1.9 \  hours

  The  time it take to travel from Daytona Beach to Fort Pierce is t_2  = 2\ hours\ and\ 51\ minutes= 2 + \frac{51}{60} =  2.85 \  hours

    The  time it take to travel from Fort Pierce to West Palm Beach is  

t_3  = 1\ hour\ and\ 23\ minutes= 1 + \frac{23}{60} =  1.38 \  hours

     The  time it take to travel from West Palm Beach to Miami t_4  = 1\ hour\ and\ 38\ minutes= 1 + \frac{38}{60} =  1.63 \  hours

Generally the average speed is mathematically represented as

      v  =  \frac{d}{t_1 + t_2 +t_3 + t_4 }

=>   v  =  \frac{382}{1.9  + 2.85 +1.38 + 1.63 }

=>    v =  49.23 \  mph

Express the product of 2x^2+7x-10 and x+5 in standard form
zimovet [89]

Answer:

2x³+17x²+25x-50

Step-by-step explanation:

Standard Form: All your numbers and variables in order of the highest exponent.

(2x²+7x-10)(x+5)

We want to distribute x and 5 to every single value.

2x³+7x²-10x+10x²+35x-50

Simplify.

2x³+17x²+25x-50

This is standard form because the highest values are on the left (x³ is larger than x²).

Can some one help me with math
hoa [83]
5 is A, because it's the only number that is whole when square rooted.
6 is confusing because it only gives you one number per answer, unless you are to add the two distances together? Then it would be 7 because X's distance is +4 and Y's distance is +3
I do not have an answer for 7
8 is 3.7 (or C)
9 is an easy one. Find out what the L and W is, and since it's a square we only need to find one of them. We square root the area and we are given 14.96662955, if rounded we get 15. So the answer is A
10 I don't understand the "estimate" for a square root number, I was not taught that.

An osprey flying horizontally 100 feet above a lake spots a fish below. It tilts its flight path downward by 45°. If the osprey
Ierofanga [76]

Answer: the rate at which its altitude is changing is -47 ft/s

Step-by-step explanation:

Given that;

ds/dt = 45 mph =  45 × 5280/3600 = 66 ft/sec

no we have to determine dx/dt

so

cos∅ = dx/dt / ds/dt

cos45° = dx/dt / 66  

dx/dt = 0.7071 × 66

dx/dt = 46.6686 ≈ 47 ft/s ( as altitude is decreasing, its negative - )

so the rate at which its altitude is changing is -47 ft/s
