How do I write log7t as a base 2 logarithm?

Answer:

x=17 or x=19

Step-by-step explanation:

(x−18)^2=1

First, simplify both sides of the equation.

x*2−36x+324=1

Then subtract 1 from both sides.

x^2−36x+324−1=1−1

x^2−36x+323=0

Factor left side of equation.

(x−17)(x−19)=0

Then set factors equal to 0.

x−17=0 or x−19=0

x=17 or x=19

Answer:

Its either x=17 or x=19

Answer:

XY = 17 UNIT

Step-by-step explanation:

Given:

TW = 3

YW = 8

XZ = 12

Find:

XY

Computation:

TW = ZW = 3

So,

XW = 12 + 3

XW = 15

So

XY = √XW²+YW²

XY = √15²+8²

XY = √289

XY = 17 UNIT

Applying the definition of perpendicular bisector and the Pythagorean Theorem, the value of XY is calculated as: 17 units.

Recall:

Considering the diagram attached below, we are given that:

[tex]TW = 3\\\\YW = 8\\\\XZ = 12[/tex]

Applying the Pythagorean theorem:

[tex]XY = \sqrt{XW^2 + YW^2}[/tex]

XW = XZ + WZ

XZ = 12 (given)

WZ = TW = 3 (congruent segments)

XW = 12 + 3

XW = 15

Plug in the values of XW and YW into [tex]XY = \sqrt{XW^2 + YW^2}[/tex]

[tex]XY = \sqrt{15^2 + 8^2}\\\\\mathbf{XY = 17}[/tex]

The answer is C.....im pretty sure I took the test

Step-by-step explanation:

Answer:

Step-by-step explanation:

On a table, you'd have two columns: one for your input(x) and one for your output(y). If given an x value, put it into the equation to solve for y, and if you have a y value, put it into the equation for x. You can also come up with your own x values and put them into the equation if you need to create a table from scratch I'm not sure what you're asking but this will help you fill in a table. Here's and example for this equation.

X              Y

1                3

2               6

3               9

Graphs are pretty simple. Just find a value on the x-axis (horizontal), find the point on the line above or below this value, and look at what number it is for the y value. You can do this backwards if you need to find y when given x.

Answer:

Step-by-step explanation:

y = 5x² - 46x + 77

If you want the roots they are 11/5 and 7 both positive.

We first convert from degrees to radians multiplying by π/180:

θ = 1000° × π/180 = 17.45 rad

The radius is:

r = d/2 = 4 in /2 = 2 inch

So, The distance traveled is given by the product of the angle in radians and the radius. This is:

d = θr = (17.45 rad)(2 inch) = 34.9 inch

Answer:

11/5

Step-by-step explanation:

the line goes up 11, and over 5, therfore the slope would be rise over run...so 11/5

Answer:

-457.96

Step-by-step explanation:

Step-by-step explanation:

273.15 + °C = K

°C = K - 273.15

0.95K to °C = 0.95 - 273.15 = -272.2°C

°C to °F

(9/5 °C) + 32 = °F

(9/5 × -272.2) + 32 = °F

-489.96 + 32 = °F

= -457.96°F

Answer:

x = 5

Step-by-step explanation:

9x - 28 = 5x - 8 (because Y and X are equal, and XZ and YZ are equal)

add 8 to both sides

9x - 20 = 5x

subtract 9x from both sides

-20 = -4x

divide 4x from both sides

5 = x

x = 5

Answer:

The object will be 2 inches above the rest position when at approximately 0.23 seconds

Step-by-step explanation:

The given parameters are;

The equation that models the distance, d, of the object in inches above or below the rest position = a×(cos(b·t))

If a = 5 and b = 5, we have;

d = 5 × (cos(5 × t))

When the object is approximately 2 inches above the ground, we have;

d = 2 = 5 × (cos(5 × t))

cos(5 × t) = 2/5

5 × t = cos⁻¹(2/5) ≈ 1.16

t =  (cos⁻¹(2/5))/5 ≈ 1.16/5

t ≈ 0.23 s

The object will be 2 inches above the rest position when t ≈ 0.23 s.

C. Reflexive property

Step-by-step explanation:

When a line segment is congruent or the same as itself, it is considered to have a property known as reflexive property.

This means line segment CE is a mirror image of itself. Therefore, line segment CE is congruent to line segment CE.

Line segment CE is what divides the figure given into two equal halves, making both parts congruent to each other.

Answer:d + q = 40 -----> d = 40 - q

10d + 25q = 760

Substitute!

10(40 - q) + 25q = 760

400 - 10q + 25q = 760

15q = 360

q = 24

d = 40 - 24

d = 16

$43.48

Step-by-step explanation:

58.89x.30=17.68

58.89-17.68=41.21

41.21x.055=2.27

41.21+2.27= $43.48

Answer:

$43.49

Step-by-step explanation:

When you take of 30%, multiply by 0.7

When you add 5.5%, multiply by 1.055

Start with $58.89

Take off 30%: 0.7 * $58.89 = $41.22

Add 5.5%: 1.055 * $41.22 = $43.49
