Graph. y−2=23(x+4) Use the Line Tool and select two points to graph the equation. Use the slope and the point provided in the equation.
Answers
The graph of the equation y − 2 = 2⁄3(x + 4) is a blue line that passes through the points (0, 2) and (3, 4).
To graph the equation `y − 2 = 2⁄3(x + 4)` using the Line Tool and selecting two points, we can use the following steps:
1. Find the slope and y-intercept of the line.
The equation is already in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope is 2⁄3 and the y-intercept is 2.
2. Find a point on the line.
The y-intercept is always a point on the line, so we can use the point (0, 2) as our first point.
3. Use the slope to find another point on the line.
The slope tells us how much to move up or down and how much to move to the right to find another point on the line. In this case, the slope is 2⁄3, so we need to move up 2 units and to the right 3 units from our first point. This gives us the point (3, 4).
4. Select the two points in the Line Tool and draw the line.
Once we have selected the two points, we can draw the line by clicking and dragging the mouse.

What is the point-slope form of a line with slope 6 that contains the same point (1,2)
Answers
The point-slope form of the line with slope 6 that contains the point (1, 2) is y - 2 = 6(x - 1).
The point-slope form of a line is given by:
[tex]\[ y - y_1 = m(x - x_1) \][/tex]
where m is the slope of the line and [tex]\( (x_1, y_1) \)[/tex] is a point on the line.
Given that the slope m = 6 and the point [tex]\( (x_1, y_1) = (1, 2) \)[/tex], we can substitute these values into the point-slope form:
y - 2 = 6(x - 1)
So, the point-slope form of the line with slope 6 that contains the point (1, 2) is y - 2 = 6(x - 1).

E.The graph has a y-intercept of 185
F.As the number of years increases, the number of dolphins in the sanctuary increases
Answers
Answer:
B, C, D, and F
Step-by-step explanation:
The graph is an exponential curve rising upwards. By looking at the graph we can tell that the graph is only increasing, it touches the y-axis at 30 and it lies in the 1st quadrant.
So, option A is wrong, as the graph is increasing.
Option B is correct. The point where graph crosses/touches the y-axis is the y-intercept. So the y-intercept is 30.
Option C is correct. As the graph lies in 1st quadrant and is positive over the entire range of values.
Option D is also correct as the graph is increasing over entire range of values.
Option E is incorrect as y-intercept is 30.
Option F is correct. Since the graph is increasing, this means with every passing year the number of dolphins is increasing.
Therefore, the correct options are: B, C, D, and F

Alma's math teacher said that there was 10 factorial (10!) possible different orders in which the problems on the next exam could be arranged. What does 10! mean?
A- 10^100
B- 10(9+8+7+6+5+4+3+2+1)
C- 10(9)(8)(7)(6)(5)(4)(3)(2)(1)
D- 10,000,000,000
Answers
Answer:
The 10! means 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 ⇒ answer C
Step-by-step explanation:
* Lets explain how to solve the problem
- Factorial number means a number which is multiply itself to its
decreasing numbers
- In mathematics, the factorial of a non-negative integer n, denoted by
n! is the product of all positive integers less than or equal to n
- That means n! = n × (n-1) × (n-2) × (n-3) × ...........× 1
- Ex: 5 ! = 5 × 4 × 3 × 2 × 1 = 120
* Lets solve the problem
- There was 10 factorial 10! possible different orders
- The meaning of 10! is the multiplication of all the numbers from
10 to 1
∴ 10! = 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1
* The 10! means 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1
The correct choice is C, 10(9)(8)(7)(6)(5)(4)(3)(2)(1). The expression 10! (ten factorial) means the product of all integers from 1 to 10, which is calculated as 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1.
Therefore, the correct choice is C. For example, 4! equals 4 × 3 × 2 × 1 = 24.
The expression 10!, read as 'ten factorial', represents the product of all integers from 1 to 10. It is calculated as follows:
10! = 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1
So, the correct choice for what 10! means is:
C- 10(9)(8)(7)(6)(5)(4)(3)(2)(1)
For example, the factorial of 4 is calculated as 4! which equals 4 × 3 × 2 × 1 = 24.
Similarly, for 10!, you multiply all integers from 10 down to 1.
Two sporting goods stores are having discount sales on basketballs. • At one store, a basketball is on sale for 20% off the regular price of $24.95. • At the other store, the same kind of basketball is on sale for 25% off the regular price of $25.80. What is the difference between the sale prices of the two stores?
Answers
Answer:

24.95 - 4.99 = 19.96 (sales price)
store B: 25.80 * 25% (or 0.25) = 6.45 (discount)
25.80 - 6.45 = 19.35
To find the difference of sales price, subtract 19.96 - 19.35 = 0.61

Answers
Answer:
See the highlighted values below.
Step-by-step explanation:
The following right angled triangle will have an angle whose cosine is 5/13.
Hypotenuse = 13 and the 2 legs will be 5 and 12 units long. The 12 is found using the Pythagoras theorem ( 13^2 = 5^2 + 12^2).
cos O = adjacent / hypotenuse = 5/13.
So sin O = opposite / hypotenuse = 12/13.
tan O = opposite / adjacent = 12/5.
csc O = 1 / sin O = 13/12.
sec O = 1 /cos O = 13/5.
cot O = 1 / tan O = 5/12.

patrick is going to paint the fence posts around the corral. the rectangular corral is 50 ft by 30 ft, with the fence posts spaced 5 feet apart. how many fence posts does patrick have to paint?
Answers
Answer:
32 posts
Step-by-step explanation:
In terms of fence-post spaces, the corral is 10 by 6, so its perimeter is ...
P = 2(10 +6) = 32 . . . . . fence post spaces.
Patrick intends to paint 32 fence posts.
Final answer:
Patrick needs to paint a total of 32 fence posts around the rectangular corral. This total counts the posts for both pairs of sides after considering that the four corner posts have been counted twice.
Explanation:
The question involves calculating the total number of fence posts needed to surround a rectangular corral. Since the corral is 50 ft by 30 ft, and fence posts are spaced 5 feet apart, we must calculate how many posts are needed on each side of the rectangle and then add them together.
To begin with, for each of the longer sides (50 ft), we would need 50 ft ÷ 5 ft/post = 10 posts per side. However, we need to add one more post to close the rectangle, so we have 10 + 1 = 11 posts on each of the longer sides. For the shorter sides (30 ft), it would be 30 ft ÷ 5 ft/post = 6 posts per side, plus the extra post to close the rectangle, resulting in 6 + 1 = 7 posts on each of the shorter sides.
To get the total number of posts, we add up the posts on all sides: (11 posts × 2) + (7 posts × 2) = 22 + 14 = 36 posts. However, we must consider that we have counted the corner posts twice, once for each side they join. Since there are four corners, we subtract four posts from our total, resulting in 36 - 4 = 32 posts that Patrick needs to paint.
Regard y as the independent variable and x as the dependent variable and use implicit differentiation to find dx/dy. x5y2 − x4y + 2xy3 = 0
Answers
Answer:
dx/dy = (x^4 - 2x^5y - 6xy^2) / (5x^4y^2 - 4x^3y + 2y^3).
Step-by-step explanation:
x^5y^2 − x^4y + 2xy^3 = 0
Applying the Product and Chain Rules:
y^2*5x^4*dx/dy + 2y*x^5 - (y*4x^3*dx/dy + x^4) + (y^3* 2*dx/dy + 3y^2*2x) =0
Separating the terms with derivatives:
y^2*5x^4*dx/dy - y*4x^3*dx/dy + y^3* 2*dx/dy = x^4 - 2y*x^5 - 3y^2*2x
dx/dy = (x^4 - 2x^5y - 6xy^2) / (5x^4y^2 - 4x^3y + 2y^3)
Answer:
[tex]\frac{dx}{dy}=\frac{-2x^5y+x^4-6xy^2}{5x^4y^2-4x^3y+2y^3}[/tex]

Differentiate with respect to y.
[tex]\frac{d}{dy}(x^5y^2)-\frac{d}{dy}(x^4y)+\frac{d}{dy}(2xy^3)=0[/tex]
Using product rule we get
[tex]x^5\frac{d}{dy}(y^2)+y^2\frac{d}{dy}(x^5)-x^4\frac{d}{dy}(y)-y\frac{d}{dy}(x^4)+2x\frac{d}{dy}(y^3)+2y^3\frac{d}{dy}(x)=0[/tex] [tex](fg)'=fg'+gf'[/tex]
[tex]x^5(2y)+y^2(5x^4\frac{dx}{dy})-x^4(1)-y(4x^3\frac{dx}{dy})+2x(3y^2)+2y^3\frac{dx}{dy}=0[/tex]
[tex]2x^5y+5x^4y^2\frac{dx}{dy}-x^4-4x^3y\frac{dx}{dy}+6xy^2+2y^3\frac{dx}{dy}=0[/tex]
Isolate [tex]\frac{dx}{dy}[/tex] terms on left side.
[tex]5x^4y^2\frac{dx}{dy}-4x^3y\frac{dx}{dy}+2y^3\frac{dx}{dy}=-2x^5y+x^4-6xy^2[/tex]
[tex](5x^4y^2-4x^3y+2y^3)\frac{dx}{dy}=-2x^5y+x^4-6xy^2[/tex]
Isolate [tex]\frac{dx}{dy}[/tex] term.
[tex]\frac{dx}{dy}=\frac{-2x^5y+x^4-6xy^2}{5x^4y^2-4x^3y+2y^3}[/tex]

Given: Circle X with a Radius r and circle Y with radius s Prove: Circle x is similar to circle y
Answers
Answer:
Step-by-step explanation:
To prove that Circle X is similar to Circle Y, we need to show that their corresponding angles are equal and their corresponding sides are proportional. We can compare the ratios of the circumference to the diameter for both circles, which are equal, implying that the angles in the two circles are equal and Circle X is similar to Circle Y.
Explanation:To prove that Circle X is similar to Circle Y, we need to show that their corresponding angles are equal and their corresponding sides are proportional. Since the radii of the two circles are different (r for Circle X and s for Circle Y), we cannot directly compare their sides. However, we can compare their ratios. If we divide the circumference of Circle X by its diameter, we get the value of pi (π), which is approximately 3.14. Similarly, if we divide the circumference of Circle Y by its diameter, we would also get pi (π). This means that the ratios of the circumference to the diameter for both circles are equal, which implies that the angles in the two circles are equal and therefore, Circle X is similar to Circle Y.
