kati45 [8]

Answer:

The required function that models the number of branches t years since Bela began studying her tree is

number of branches = $60(1.83)^{\frac{t}{2.9} }$

Step-by-step explanation:

Let t be the time in years

Initially Bela's tree had 60 branches.

therefore the function that can be used to model the number of branches after t years will be given by

number of branches( after t years) $= 60\times(1 + \frac{83}{100})^{\frac{t}{2.9} } = 60(1.83)^{\frac{t}{2.9} }$

After each soccer practice Scott Runs 4 sprints of 10 yards each complete exclamation to find how many practices it will take fo

Tpy6a [65]

Answer:

Scott will have to do 44 practices

Step-by-step explanation:

Let X be the number of yards per practice.

Let P = number of practice Scott needs to do.

Multiply 20 yards by 4 sprints

X = 20yards × 4 sprints = 80 yards

Number of yards he had to sprint per practice will be:

1 mile = 1760 yards

Converting from miles to yards

X = 1760 × 2 miles = 3520 yards

Number of practice,P Scott need to do = (3520/80)yards

Number of Practice,P = 44

What is the surface area of a sphere with a radius of 13 units?

allochka39001 [22]

Answer:

2,122.64 square units or $676 \pi$ units squared

Step-by-step explanation:

The surface area of a sphere can be found using the formula $A=4\pi r^2$ . Since the radius is 13 units, substitute r=13.

$SA=4\pi r^2\\SA = 4 \pi (13)^2\\SA = 4 \pi *169\\SA = 2122.64$

Without multiplying 3.14 for $\pi$ , the answer is

$SA = 169*4 \ pi\\SA = 676 \pi$
