Answer:

$=\left(-\frac{19}{2},\:-2\right)$

Step-by-step explanation:

$\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)\\\\\left(x_1,\:y_1\right)=\left(-10,\:5\right),\:\\\left(x_2,\:y_2\right)=\left(-9,\:-9\right)\\\\=\left(\frac{-9-10}{2},\:\frac{-9+5}{2}\right)\\\\Simplify \\=\left(-\frac{19}{2},\:-2\right)$

20. Which set of parametric equations over the interval 0 ≤ t ≤ 1 defines a line segment with initial point (–5, 3) and terminal

lesya [120]

Given:

Initial point = (–5, 3)

Terminal point = (1, –6)

To find:

The set of parametric equations over the interval 0 ≤ t ≤ 1.

Solution:

The interval is 0 ≤ t ≤ 1, initial point is (–5, 3) and terminal point is (1, –6). It means,

$x(0)=-5,y(0)=3$

$x(1)=1,y(1)=-6$

Put t=1 in each parametric equation.

In option A,

$x(1)=-5+1=-4\neq 1$

In option B,

$x(1)=-5+3(1)=-5+3=-2\neq 1$

In option D,

$x(1)=-5+8(1)=-5+8=3\neq 1$

Therefore, options A, B and D are incorrect.

In option C,

$x(1)=-5+6(1)=-5+6=1$

$y(1)=3-9(1)=3-9=-6$

Put t=0 in x(t) and y(t).

$x(0)=-5+6(0)=-5$

$y(0)=3-9(0)=3$

Since, only in option C $x(0)=-5,y(0)=3,x(1)=1,y(1)=-6$ , therefore, the correct option is C.

1/5 or 0.23 which is bigger

avanturin [10]

0.23 is bigger, because 1/5 is only 0.20 in decimal form

Who can help me on my math I’m failing can y’all please help me on some questions.

Answer:

7 quarters, 8 nickels

Step-by-step explanation:

So the system of equations you have is:

x + y = 15

0.25x + 0.05y = 2.15

Here's how to solve:

first, multiply both sides of the equation 0.25x + 0.05y = 2.15 by 100 to get rid of the decimal places:

25x + 5y = 215

Then, you can divide both sides by 5 to simplify it more:

5x + y = 43

Now, you have the system of equations:

5x + y = 43

x + y = 15

Now subtract the two equations:

4x = 28

divide both sides by 4

x = 7

plug x = 7 into the equation x + y = 15 to solve for y:

7 + y = 15

subtract 7 from both sides

y = 8

So you know that there are 7 quarters and 8 nickels.
