Answer:

532

Step-by-step explanation:

532 = 2·2·7·19

There are 24 possible 3-digit numbers from the set {2, 3, 5, 7}. Of those, 6 have four factors: 372, 375, 532, 572, 732, 735.

The sums of factors of these numbers are ...

38, 18, 30, 28, 68, 22

The number of interest is 532.

Find the equation of the line perpendicular to the given line, through the given point x=-3; (1,8)

Bumek [7]

Answer:

y = 8

General Formulas and Concepts:

Algebra I

Coordinates (x, y)

Slope-Intercept Form: y = mx + b

m - slope
b - y-intercept

Step-by-step explanation:

Step 1: Define

Identify

[Line] x = -3

Point (1, 8)

Step 2: Find Perpendicular Line

A vertical line's slope is undefined.

The negative reciprocal of an undefined slope is 0.

Define perpendicular slope: m = 0
Substitute in m [Slope-Intercept Form]: y = 0x + b
Simplify: y = b

Given point (1, 8), our y-value is equal to 8.

∴ the perpendicular line is y = 8.

Answer:

$\Huge\boxed{x=12}$

Step-by-step explanation:

Hello There!

The following angles are complementary angles

Complementary angles have a sum of 90

So to solve for the variable (x) we use this equation

90 = 35 + 4x + 7

step 1 combine like terms

35+7=42

now we have

90 = 4x + 42

step 2 subtract 42 from each side

90 - 42 = 48

42 - 42 cancels out

now we have

48 = 4x

step 3 divide each side by 4

4x/4 = x

48 / 4 = 12

we're left with x=12

Willing to brainlist solve 16-17 please during this exam

Answer:

16. B

17. B

Step-by-step explanation:

16. The intercept form of the parabola is

$y=a(x-x_1)(x-x_2),$

where $x_1, x_2$ are two x-intercepts.

In your case,

$x_1=2\\ \\x_2=-8$

$y=a(x-2)(x-(-8))\\ \\y=a(x-2)(x+8)$

To find a, substitute coordinates of the point (-6,-4) parabola is passing through

$-4=a(-6-2)(-6+8)\\ \\-4=-16a\\ \\a=\dfrac{1}{4}$

and

$y=\dfrac{1}{4}(x-2)(x+8)$

17. The vertex form of the parabola equation is

$-2p(y-k)=(x-h)^2,$

where (h,k) are the coordinates of the vertex and sign "-" because parabola goes down.

In your case, vertex is (2,3), so

$-2p(y-3)=(x-2)^2$

The vertex is 3 units from the focus, then

$\dfrac{p}{2}=3\\ \\p=6$

The equation of the parabola is

$-2\cdot 6(y-3)=(x-2)^2\\ \\y=-\dfrac{1}{12}(x-3)^2+3$
