NEED HELPPPPP
Arada [10]

Answer: $245.01

Step-by-step explanation:

A=P(1+rn)n⋅t

A = total amount

P = principal or amount of money deposited,

r = annual interest rate

n = number of times compounded per year

t = time in years

In this example we have

P=$200 , r=7% , n=1 and t=3 years

After plugging the given information we have

A=200(1+0.071)1⋅3=200⋅1.073=200⋅1.225043=245.01

Hope this helps, give me brainliest

Does 4=-3/2(-4)-2 equal out to (-4,4)
Marizza181 [45]

Answer:

yes

Step-by-step explanation:

well im going to assume that the original equation is y = -3/2x - 2

if that is the case, then if you plug in the numbers

4 = -3/2(-4) - 2

4 = 6 - 2

4 = 4

so yes when x is -4, y is 4; (x, y) (-4, 4)

PQRST is a rectangular-based pyramid with a height of 9cm.
Diano4ka-milaya [45]

Answer:

54.1° (1 dp)

Step-by-step explanation:

Let the center point of the rectangle PQRS = M

Calculate the length of the line SM using Pythagoras' Theorem:

          a² + b² = c²

(11/2)² + (7/2)² = SM²

              42.5 = SM²

                SM = √42.5 cm

The height of the pyramid is 9 cm,  therefore, MT = 9

Now we have a right angled triangle with base SM and height MT and hypotenuse ST

We want to find the angle TSM, so we can use the trig formula tan x = O/A, where x is the angle, O is MT and A is SM

tan TSM = MT/SM = 9/√42.5

TSM = arctan (9/√42.5) = 54.082088°

So the angle between the line ST and the plane PQRS = 54.1° (1 dp)
