Jim is a furniture salesman. his weekly pay is $300 plus3.5% of his total sales for the week.jim sell x dollar's worth of furnit

Lesechka [4]

For this case, the first thing we must do is define a variable.
We have then:
x: total sales for the week
We now write the equation that models the problem.
We have then:
p (x) = 0.035x + 300
Answer:
a function, p (x), which can be used to determine his pay for the week is:
p (x) = 0.035x + 300

Please help I’m so lost

Marysya12 [62]

Answer:

u = 7.21

Step-by-step explanation:

The magnitude of u is just the distance between the two points. The coordinates of the left-most point are (-2,-8) and the coordinates of the right point are (4, -4). I'm assuming the x coordinates here because we don't actually know the scale.

Ok so from these points, you can draw a triangle (u can see it in the attached file).

From the coordinates we can tell the lengths of the sides, and the triangle shows that u is the hypotenuse of the triangle. This triangle is also a right triangle, so u can use Pythagoras' theorem to find the length of u.

$a^{2}+b^{2} = c^{2} \\6^{2}+4^{2} = c^{2} \\\sqrt{6^{2} +4^{2} } = c\\\sqrt{36+16} = c\\7.21 = c$

Since c = u, we know now that the magnitude of u is 7.21

Hope this helps!

Rationalize the denominator of the given expression

Grace [21]

You multiply top and bottom of the fraction by the conjugate of 5 - √2 which is 5 + √2. This produces a rational denominator:-

= √7 ( 5 + √2) / (5 - √2)(5 + √2)

= √7 ( 5 + √2) / (25 -2)

= (√7 ( 5 + √2)) / 23 answer

Write the equation of a circle with diameter endpoints of (-14,1) and (-10,9)

lara31 [8.8K]

Answer:

$(x+12)^2+(y-5)^2=80$

Step-by-step explanation:

First, we see that the center of the circle is (-12, 5) by taking the midpoint of the circle. Secondly, the length of diameter is $\sqrt{4^2+8^2}=\sqrt{80}$ .
