Answer:

a=180-2.50d

Step-by-step explanation:

If Penny starts with a balance of $180, and a represents the account left in her account after d days. we can start modeling an incomplete equation:

a=180

We are then told that she spends $2.50 each (d) day. This can be represented as:

2.50d

Let's now include the expression into the incomplete equation. Remember that since she is spending, the 2.50d will be subtracted from her balance of $180:

a=180-2.50d

Hi, can someone help me on this. I'm stuck --
CaHeK987 [17]

Answer:

a) Fx=-5N  Fy=-5*sqrt(3) N   b) Fx= 5*sqrt(3) N    Fy=-5N

c) Fx=-5*sqrt(2) N    Fy=-5*sqrt(2)   N

Step-by-step explanation:

The arrow's F ( weight) component on axle x  is Fx= F*sinA  and on axle y is

Fy=F*cosA

a) The x component and y component both are opposite directed to axle x and axle y accordingly.  So both components are negative.

So Fx = - 10*sin(30)= -5 N      Fy= -10*cos(30)= -10*sqrt(3)/2= -5*sqrt (3) N

b) Now the x component  is co directed to axle x , and y component is opposite directed to axle y.

So x component is positive and y components is negative

So Fx = 10*sin(60)= 5*sqrt(3) N       Fy= -10*cos(60)= -10*1/2= -5 N

c)The x component and y component both are opposite directed to axle x and axle y accordingly.  So both components are negative.

So Fx = - 10*sin(45)= -5*sqrt(2)  N    

 Fy= -10*cos(45)= -10*sqrt(2)/2= -5*sqrt (2) N

Evaluate each function. Step by step.
Usimov [2.4K]

Answer:

Substitute what t and n equals to in the equation and just solve using algebra.

So number 2, plug in -3 where ever the variable N is located in and solve.

g(-3) = 3(-3)^2+3+2(-3)  ---> g(-3) = 27+3-6 ---> g(-3) = 24 That's the answer for 2.

For 1

plug in -5 into the t variable and solve.

k(t) = -2 |3(-5)| + 2 Since the || is between the 3 and 5, answer will be positive.

k(t) = -2(15)+2

k(t) = -28

A building 64 ft high casts a 288-ft shadow. Sarah casts an 18-ft shadow. The triangle formed by the building and its shadow is
Rzqust [24]

s/18=64/288  multiply both sides by 18

s=1152/288

s=4 ft

So Sarah is four feet tall.
