What is the equation of the line perpendicular to 2x − 5y = −35 that contains the point (10, 4)?

Gnoma [55]

Perpendicular has slope that multiplies to -1 in other sloope

thsi one

2x-5y=-35
-5y=-2x-35
y=2/5x+7
slope=2/5
2/5 times -5/2=-1
y=-5/2x+b
findn b
(10,4)
(x,y)
4=-5/2(10)+b
4=-25+b
21=b
y=-5/2x+21
2y=-5x+42
5x+2y=42

Timothy built a base for a circular tabletop. The base can support a tabletop with a radius of at least 6 inches, but not more t

neonofarm [45]

Let

r------> the radius of the circular tabletop

we know that

$r\geq 6\ in$

$r\leq23\ in$

$6\ in \leq r \leq 23\ in$

The area of a circle is equal to

$A=\pi r^{2}$

where

r is the radius of the circle

Part a) What is the smallest possible area of the tabletop that will fit on Timothy’s table base?

we know that

the smallest possible area of the tabletop is for $r=6\ in$

Substitute the value of r in the formula

$A=\pi 6^{2}$

$A=113.09\ in^{2}$

Round to the nearest whole square inch

$A=113\ in^{2}$

therefore

the answer part a) is

the smallest possible area of the tabletop is $113\ in^{2}$

Part b) What is the largest possible area of the tabletop that will fit on Timothy’s table base?

we know that

the largest possible area of the tabletop is for $r=23\ in$

Substitute the value of r in the formula

$A=\pi 23^{2}$

$A=1,661.90\ in^{2}$

Round to the nearest whole square inch

$A=1,662\ in^{2}$

therefore

the answer part b) is

the largest possible area of the tabletop is $1,662\ in^{2}$

Subtract 5p + 8q from the sum of 5p + 4q and – 9p + 69.

Mice21 [21]

Answer:

-9p -4q + 69

Step-by-step explanation:

5p +4q + (-9p +69)

=> 5p + 4q -9p +69

=> -4p +4q +69

Now, we need to subtract 5p +8q from -4p + 4q +69

=> -4p +4q +69 - (5p +8q)

=> -4p + 4q +69 - 5p -8q

=> -9p -4q + 69
