Answer:

A

Step-by-step explanation:

Answer:

Step-by-step explanation:

we are given that 1 angle equals 27 and the other two are equal.

180-27=153. and the other two are equal so they each equal 76.5 (153 divided by 2) now since one of the angles is supplementary with angle x, they together must equal 180 so: 180-76.5=x, x=103.5

Answer:

Slope: 6

Y-intercept: 4

Equation: y=6x+4

Step-by-step explanation:

For slope you do change in y over change in x so its 10-4/1-0 in this case which gets you 6/1 or 6 for your slope

It crosses the y-axis at (0,4) so your y-intercept is 4

The base equation is y=mx+b m is slope b is y-intercept so you plug in your values and get y=6x+4

Complete the square:

2x² + 9x - 18

2(x² + 9/2 x) - 18

2(x² + 9/2 x + 81/16 - 81/16) - 18

2(x² + 2 (9/4) x + (9/4)²) - 81/8 - 18

2(x + 9/4)² - 225/8

If you're not familiar with the method, the idea is to get a quadratic from the standard form

ax² + bx + c

into its vertex form

a (x - h)² + k

where (h, k) is the vertex of the parabola associated with the quadratic.

Expand the vertex form to get

a (x² - 2xh + h²) + k

ax² - 2ahx + ah² + k

For the two forms to be equivalent, we must have

-2ah = b

ah² + k = c

which means

h = -b/(2a)

k = c - ah² = c - b²/(4a)

In this case, a = 2, b = 9, and c = -18, so

h = -9/(2 • 2) = -9/4

k = 18 - 9²/(4 • 2) = -225/8

The graph that represents a function is graph (1)

The attached graphs represent the given parameters

From the attached figure, we can see that there are four graphs

Each of the four graphs represented different functions

As a general rule,

A graph that represents a function must pass the vertical line test

The vertical line test is such that:

If a line is drawn from the x-axis, it must touch the curve not more than one times

The graph that passes this test is graph (1)

This is so because it is a quadratic graph

Hence, the function graph is (1)

Answer:

true

Step-by-step explanation:

Answer:

P(A and B)=0.2

Step-by-step explanation:

P(A or B) represents mutually exclusive events, which mean they cannot occur at the same time. For example, you can't turn your head left and right at the same time. Their probabilities would be added as a result.

P(A and B) represents events that do occur at the same time, so the probabilities are multiplied. P(A and B)=P(A)*P(B)=0.5*0.4=0.2 or 20%

Answer:

About 158 times

Step-by-step explanation:

Represent the rate of human heart with H and sparrow's heart with S

[tex]H = 1,533,000\ times[/tex]

[tex]S = 241,776,000\ times[/tex]

Required

Determine how many times faster is S than H

To do this, we simply divide S by H i.e.

[tex]Number = \frac{S}{H}[/tex]

[tex]Number = \frac{241,776,000}{1,533,000}[/tex]

[tex]Number = 157.714285714[/tex]

[tex]Number = 158[/tex] --- approximated

Hence, the sparrow's heart beats about 158 times faster than the human hearts

Answer:

x>11 is the solution to both equations.

Step-by-step explanation:

I apologize for late response I've been busy lately. Anyways here ya go! :

From what I understand it wants us to solve "9x-4>95" so that's what I'll do.

add 4 to each side

9x>99

divide each side by 9

x>11 is the solution to 9x-4>95

For 4x+10>54

subtract 10 from each side

4x>44

divide each side by 4

x>11 is the solution to 4x+10>54

Answer:C 4x-y=2

Step-by-step explanation:

The equation of the line that has a slope of 4 is 4x - y = 10.

Option D is the correct answer.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

Slope = 4.

The line contains (3, 2).

The equation of the line.

y = mx + c

m = 4

(3, 2) = (x, y)

2 = 4 x 3 + c

2 = 12 + c

c = 2 - 12

c = -10

Now,

y = 4x - 10

4x - y = 10

Thus,

The equation of the line is 4x - y = 10.
