PLEASE HELP WILL MARK BRAINLIEST!!
Arturiano [62]

Answer:

Yes.

Step-by-step explanation:

Though x and y can be achieved in a system of equations. The equation

x (t)=0.0411905(t^2)+(-0.164619)t+28.0114

And

y (t)=-0.024127(t^2)+(-0.591143)t+(-87.4403)

Are not system of equations but rather two different models of equations. Nevertheless

To find t in the first equation, x(t) has to be equal to zero.

When the t is substituted in the second equation, t will completely disappear. Given the value of y(t) and vice versa.

Kimberly is ordering bath towels and washcloths for the inn where she works. The total cost of the order is T=6b+2w, where T is
Arturiano [62]

Given:

The total cost of the order is

T=6b+2w

where, T is the total cost, b is the number of bath towels, and w is the number of wash cloths.

Her budget is $85.

To find:

The constraints, so that she can order a maximum of washcloths or bath towels.

Solution:

We have,

T=6b+2w

Her budget is $85. So, total cost is less than or equal to 85.

6b+2w\leq 85       ...(i)

For maximum number of bath towels, the number of wash cloths is 0.

6b+2(0)\leq 85

6b\leq 85

Divide both sides by 6.

b\leq \dfrac{85}{6}

b\leq 14.167

For maximum number of wash cloths, the number of bath towels is 0.

6(0)+2w\leq 85

2w\leq 85

Divide both sides by 2.

w\leq \dfrac{85}{2}

w\leq 42.5

Therefore, the required constraints for maximum of washcloths or bath towels are w\leq 42.5 and b\leq 14.167 respectively.
