Answer:
1000
Step-by-step explanation:
The easiest way to go about this is by turning our number into ABCD.
A will be in the 1000th spot, B 100th, C 10th, and D 1st.
A has to be ≥ 5. So 5, 6, 7, 8, 9.
B has to be a prime number. 2, 3, 5, 7.
C is able to be any number it wants, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
Since the number is odd, D has to be 1, 3, 5, 7, 9.
A has 5 different possibilities. B has 4, C has 10, and D has 5.
You'll then multiply all of these numbers for your answer.
5 * 4 * 10 * 5 = 1000

The curve above is the graph of a sinusoidal function. It goes through the points (- 4, 0) and (2, 0) Find a sinusoidal function that matches the given graph If needed, you can enter pi = 3.1416 as in your answer, otherwise use at least 3 decimal digits
A sinusoidal function that matches the given graph is y=cosπx/3+2.
From the given question, the curve is the graph of a sinusoidal function.
It goes through the points (- 4, 0) and (2, 0).
We have to find the sinusoidal function that matches the given graph.
For this problem, we can use either of these general equations :
y = Asin(Bx + C) + D or y = Acos(Bx + C) + D.
A = amplitude = distance on Y-axis from centre of graph to highest or lowest point.
So from the given graph
A = 1
T = period = distance on X-axis over one complete cycle
So from the given graph
T = 6.
So B=2π/6 =π/3
D = distance that graph has been moved up or down on the Y-axis
D = 0
C= horizontal shift (left side if positive)
From the given Graph
C = 2
So, equtaion is
y = Acos(Bx + C) + D
Putting the each variable value
Using π =3.1416.
y = 1*cos(π/3 x + 2) + 0
y = cosπx/3 + 2
Hence, a sinusoidal function that matches the given graph is y=cosπx/3+2.

Robert is standing on a bridge that spans a canyon. He drops a pebble from the bridge, and records how long the pebble takes to reach the water below. If the pebble takes 5.49 seconds to reach the water, what is the height of the bridge?
"Height of the bridge is 148 m"
Given :
time = 5.49 s
Since pebble is dropped from a height it will have acceleration due to gravity (g = 9.8 m/s²) ∴ a = 9.8 m/s²
Let us assume that Initial velocity (v) is 0 m/s² (pebble is not moving)
we have to find distance d = ?
Now according to formula
d = vt + 1/2 at²
Now putting the values in the formula
d = 0 × 5.49 + 1/2 × 9.8 × (5.49)²
d = 0 + 147.68
d = 147.68 ≈ 148 m
Therefore the height of the bridge is 148 m.

so I am doing Eureka math and 7th grade kinda need help....rewrite the expression by using distributive property and collecting like terms. 2 4/5v - 2/3(4v+1 1/6)
Answer:
2/15v + 7/9
Step-by-step explanation:
We take our base equation, then we will make every mixed number into an improper fraction. This will give us 14/5v - 2/3(4v+ 7/6). Then we will open the parentheses. This gives us: 14/5v - 8/3v+ 14/18. We will bring both the v's to a common denominator, giving us 42/15v - 40/15v+ 14/18. Then we can subtract and simplify. 2/15v + 7/9.

Step-by-step explanation:Hey! Let's help you with out with this question!
Alright! So! We're trying to figure out the slope of the table. And how do we do that? Well, there is actually a formula that can help us here! And that is using the slope between two points.
What is the formula for the slope between two points?The formula is as follows:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
It allows us to figure out the slope by taking two coordinate points and sub them into the formula to find m, which in this case is the slope!
Let's use this equation twice, we do this to make sure that the slope is consistent throughout the table.
Using the formula for the first two points:The first two points are:
(3, 36)(6, 30)Now, we apply the formula as such:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{30-36}{6-3}[/tex]
[tex]m=\frac{-6}{3}[/tex]
[tex]m=-2[/tex]
Alright, so we have a slope [tex]m=-2[/tex] for the first two points! Let's check if the last two points have the exact same slope as well!
Using the formula for the last two points:The last two points are:
(9, 24)(12, 18)We apply the formula again!
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{18-24}{12-9}[/tex]
[tex]m=\frac{-6}{3}[/tex]
[tex]m=-2[/tex]
Conclusion:Well, what do you know? Given our application of the slope between two points, we get a common answer [tex]m=-2[/tex]. So, therefore, it would be b) [tex]m=-2[/tex]

We were told that Wesley willed his estate to Margaret, Betty Jo, and Johnny.
Given that he gave Margaret $20,000. Betty Jo got 22 times as much as Margaret, it means that the amount the at Betty Jo got is 22 * 20000 = 440000
Given that Johnny got 32 times as much as Margaret, it means that the amount that Johnny got is
20000 * 32 = 640000
Therefore, the total value of the estate is
20000 + 440000 + 640000 = 1100000
The total value of the estate is $1,100000

Given two circles on a coordinate plane, use transformations to prove that both circles are similar
The two circles are said to be similar because they undergo a rigid transformation that does not change its shape.
How to prove similarity using transformation?A similarity transformation is defined as one or more rigid transformations (reflection, rotation, translation) followed by a dilation. Now, when a figure is transformed using a similarity transformation, an image is created that is similar to the original figure. This means that, two figures are similar if a similarity transformation will map the first figure to the second figure.
By definition of similarity transformation, looking at the given diagram, both shapes are circles and as such it is obvious that one circle has been dilated by a scale factor to get the other circle.
Thus, they have the same shape and are similar circles.

What is the answer for this equation 3X+y=5
The equation
[tex]3x+y=5[/tex]has two variables: x and y.
And since we have only one equation, the variables have infinite possible values, which are related to that equation.
Another way of seeing that is by calling x the independent variable, and then y will be the dependent variable (its value depends on the value of x).
So, we can isolate y on the left side of the equation, to obtain:
[tex]\begin{gathered} 3x+y=5 \\ \\ 3x+y-3x=5-3x \\ \\ y=-3x+5 \end{gathered}[/tex]Now, we see that the above equation represents a line (an infinite set of points), that has a slope -3 and a y-intercept 5.
Therefore, all the points on that line are solutions to the given equation.

Maria can draw a number line connecting the points 0 and 12, then divide the distance between them into four equal parts. The division operation produces the location of the point closest to zero.
What is number line ?A number line is a picture of a graduated straight line that serves as a visual representation of real numbers in elementary mathematics. Every point on a number line is assumed to be a real number, and every real number is assumed to be a point.
Integers are frequently represented as specially marked points evenly spaced on a line. Despite the fact that the image only shows the integers from -3 to 3, the line includes all real numbers, which continue indefinitely in each direction, as well as numbers that are between the integers. It is frequently used to help teach simple addition and subtraction, particularly with negative numbers.
The number line is also known as a real line or real number line in advanced mathematics.

IMPORTANT: SUM OF ALL THREE ANGLES OF A TRIANGLE EQUAL 180
For angle 1 we add 59+90 since those are the 2 known angles
90+59=149
Now subtract by 180
180-149=31
Angle 1 is equal to 31
Now for angle 2 we subtract 59 from 180 since it is on a flat surface the sum of those angles will equal 180 degrees
180-59=121
Angle 2 is 121 degrees
Now for angle 3 we add 121 and 12 since we know those 2 angles
121+12=133
