$4\ tomatoes\ :\ 3.40\ dollars$

Divide each side by 4 (division property of equality lets us do this) to find the price of one tomato.

$1\ tomato\ :\ \boxed{0.85\ dollars}$ (85 cents)

An engineer is designing a runway for an airport. Several planes will use the runway and the engineer must design it so that it

swat32

Answer:

d=117.33 m

Step-by-step explanation:

Initial velocity of planes, u = 0 (because they are at rest)

Acceleration, a = 3.3 m/s²

Final take off speed, v = 88 m/s

We need to find the minimum allowed length for the runway. Let it is d. d will be the distance. It can be calculated using third equation of motion as follows :

$v^2-u^2=2ad\\\\d=\dfrac{v^2-u^2}{2a}$

Putting all the values, we get :

$d=\dfrac{88^2-0^2}{2\times 33}\\\\d=117.34\ m$

Hence, the minimum allowed length for the runway is 117.33 m.

<h3>How to find the equation of linear regression using a calculator?</h3>

To find the equation, we need to insert the points (x,y) in the calculator.

For this problem, the points (t,v) are given as follows:

(2, 500), (3, 700), (4, 900), (5, 110)

Hence, inserting these points into a calculator, the equation is given by:

f(x) = 200x + 100.

Answer:

$\cos{A}=\pm\sqrt{\dfrac{1+\cos{x}}{2}}$

Step-by-step explanation:

$\cos{A}=\cos{\frac{x}{2}}=\pm\sqrt{\dfrac{1+\cos{x}}{2}}$

Apparently, you're supposed to recognize that the formula tells you the value of cos(x/2).
