PLEASE ANSWER I NEED HELP WITH NUMBER 6 AND 7!!

Given:

A table of values of a linear function.

To find:

The slope, y-intercept and equation of the function.

Solution:

Take any two points on the table.

Let the points are (-1, -3) and (0, -6).

Slope of the line:

[tex]$m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]$m=\frac{-6-(-3)}{0-(-1)}[/tex]

[tex]$m=\frac{-6+3}{0+1}[/tex]

[tex]$m=\frac{-3}{1}[/tex]

m = -3

Slope of the function = -3

y-intercept of the function is the point where x = 0.

In the table y = -6 when x = 0

y-intercept = -6

Equation of a line:

y = mx + c

where m is the slope and c is the y-intercept

y = -3x + (-6)

y = -3x - 6

Equation of a function is y = -3x - 6.

The slope of the function's graph is 3, the y-intercept is 2, and the equation for the function is y = 3x + 2.

To find the slope of the function's graph, we can use the formula: slope = (change in y) / (change in x). We can choose any two points from the table and calculate the slope. Let's choose the points (0,2) and (1,5). The change in y is 5 - 2 = 3, and the change in x is 1 - 0 = 1. Therefore, the slope is 3/1 = 3.

To find the y-intercept of the function's graph, we can use one of the points from the table. Let's use the point (0,2). Since the y-intercept is the value of y when x = 0, the y-intercept is 2.

The equation for a linear function is y = mx + b, where m is the slope and b is the y-intercept. So for this function, the equation is y = 3x + 2.

Answer:

x = 55

The angles are complementary

Step-by-step explanation:

Since those angles add up to be 90:

2x-20 = 90

Add 20 to both sides:

2x = 110

x = 55

Answer:

The area of the shaded triangular section is 72 square inches

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The rectangular stained glass can be divided into 24 identical triangular parts

step 1

Determine the area of complete rectangle

[tex]A=(48)(36)=1,728\ in^2[/tex]

step 2

Divide the area of complete rectangle by 24

[tex]1,728/24=72\ in^2[/tex]

therefore

The area of the shaded triangular section is 72 square inches

Answer:

72 square inches

Step-by-step explanation:

The image is shown below.

The area of a rectangle is length times width.

Length is 48 and width is 36

Hence, area of whole rectangle is:

Area = 48 * 36 = 1728

Now, the whole figure is broken down into

24 congruent triangles

So, each triangle's area is:

1728/24 = 72 square inches

The shaded region is ONE of the triangles, so the shaded region area is:

72 square inches

Answer:

The distance across the river from Omkar to the big rock is 72 meters.

Step-by-step explanation:

Using the given information draw as triangle as shown below.

According to angle sum property, the sum of interior angles of a triangle is 180°.

In triangle ABC,

\angle A+\angle B+\angle C=180^{\circ}

98^{\circ}+33^{\circ}+\angle C=180^{\circ}

131^{\circ}+\angle C=180^{\circ}

\angle C=180^{\circ}-131^{\circ}=49^{\circ}

The measure of angle C is 49°.

Sine formula:

\frac{a}{\sin a}=\frac{b}{\sin b}=\frac{c}{\sin c}

Using sine formula in triangle ABC, we get

\frac{AC}{\sin B}=\frac{AB}{\sin C}

\frac{AC}{\sin 33^{\circ}}=\frac{100}{\sin 49^{\circ}}

AC=\frac{100}{\sin 49^{\circ}}\times \sin 33^{\circ}

AC=\frac{100}{0.7547}\cdot0.544639

AC=72.166

AC\approx 72

Therefore the distance across the river from Omkar to the big rock is 72 meters.

The probability that the backpack is pink or canvas is option (c) 0.9.

The probability that the backpack is pink or canvas can be calculated using the formula for the probability of the union of two events:

P(A or B) = P(A) + P(B) - P(A and B).

According to the question,

A represents: the event that the backpack is pink

B represents: the event that the backpack is the canvas

Substituting the given probabilities, we get:

P(pink or canvas) = 0.7 + 0.7 - 0.5 = 0.9.

So, the probability that the backpack is pink or canvas is option (c) 0.9.

20

Step-by-step explanation:

Final answer:

The least common denominator for the fractions 2/5, 1/2, and 3/4 is 20, as it is the smallest number that all denominators can divide into without leaving a remainder.

Explanation:

The least common denominator (LCD) of the fractions 2/5, 1/2, and 3/4 is the smallest number that can be divided evenly by each of the denominators (5, 2, and 4, respectively). To find the LCD, we can list out the multiples of each denominator until we find a common multiple.

The multiples of 5 are 5, 10, 15, 20, 25, and so on. The multiples of 2 are 2, 4, 6, 8, 10, 12, and so on. The multiples of 4 are 4, 8, 12, 16, 20, and so on. When we look at these lists, the smallest number that appears in all three lists is 20. Therefore, 20 is the least common denominator for the fractions 2/5, 1/2, and 3/4.

Step-by-step explanation:

Similarity in Mathematics refers to two shapes resembling each other such that one can be acquired from the other using a sequence of dilations and rigid transformations. They have the same angle measures and proportional side lengths.

In the field of Mathematics, particularly in Geometry, similarity refers to the concept that alludes to how well two shapes resemble each other. Two shapes are considered similar if you can obtain one from the other using a sequence of stretches, shrinks (know as dilations), and rigid transformations (like rotation, reflection, or translation).

In other words, option D is the most accurate: If there is a sequence of rigid transformations and dilations, that take one figure to the other, then they are similar. It's important to note that the characteristics of similar figures include having the same angle measures and proportional side lengths.

Answer:

125.60

Step-by-step explanation:

the formula for the area of a cylinder is A=2πRH+2πRsquared. I find it easiest to multiply pi by 2 instead of anything else which is 6.28. Then I multiply the radius (2) times the height (8) equaling 16. Then you multiply that number by 6.28. Equaling 100.48. Then you have to do the second part which is radius (2) squared equaling 4. Then you multiply that by 6.28, equaling 25.12. then you add the two sums (25.12+100.48=125.60).

hope that makes sense!!

Answer:

$5000

Step-by-step explanation:

To get the amount earned as commission, we deduct the fixed pay from the total earned pay. Given the total monthly earnings as $2400 while fixed pay of $2200, in this case, the amount of commission will be

Commission= 2400-2200=200

Since the commission is 4% of the total sales, then the total sales equivalent to 100% is given by cross multiplication

If4%=$200

100%=?

Total sales will be 100%*$200/4%=$5000

? is the hypotenuse of the right triangle formed.

Using Pythagoras' identity on the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
