Answer:

130

Step-by-step explanation:

Recall that order of operations rules state that multiplication must be carried out before addition.

Thus, 18 + 4(28) = 18 + 112, after multiplying 28 by 4.

Next, combine these two constants: 18 + 112 = 130

Sketch the curve represented by the parametric equations (indicate the orientation of the curve), and write the corresponding re

raketka [301]

Answer:

(See explanation below for further details).

Step-by-step explanation:

Let be a parametric curve represented by $x = 3\cdot t - 5$ and $y = 5\cdot t + 1$ , where $t$ is the parametric variable.

The curve is represented graphically with the help of a graphing tool, whose outcome is included in the image attached below. The corresponding rectangular equation is found by eliminating t of each equation.

$t = \frac{x+5}{3}$ and $t = \frac{y-1}{5}$

$\frac{x+5}{3} = \frac{y-1}{5}$

$5\cdot (x+5) = 3\cdot (y-1)$

$5\cdot x +25 = 3\cdot y - 3$

$5\cdot x -3\cdot y = -28$

The parametric equations represents a linear function (first-order polynomial).

What are the square roots of 36100?

sleet_krkn [62]

$\huge\text{Hey there!}$

$\large\textsf{What are \bf the square roots of 36,100?}$

$\mathsf{\sqrt{36,100}=190\times190 = \bold{190}^2}$

$\mathsf{190^2=36,100}$

$\mathsf{(- 190)^2=36,100}$

$\mathsf{190\times190=36,100}$

$\mathsf{\sqrt{36,100}=\bf 190}$

$\mathsf{-\sqrt{36,100}=\bf -190}$

$\boxed{\boxed{\large\text{Answer: \huge \bf -190 and 190}}}\huge\checkmark$
