Answer: 0.00703
Step-by-step explanation: The ordinary number, or standard form, of this expression would be 0.00703 because here, we are multiplying 7.03 in scientific notation by a power of ten that is negative. If any exponential power of 10 is being multiplied and is negative, the digits move that same number of places to the right of the decimal point to render a smaller number than it was in the expression. Hope this helps!
A ball is hit from the ground. When the ball has traveled a horizontal distance of d meters, its height, h, in
meters, can be modeled by the function h (d) = -
1 d + d.
What is the horizontal distance from the point where the ball is hit to the point where the ball lands on the
ground?
nour in the snaca nrovided
Answer:
125 meters
Step-by-step explanation:
The ball will hit the ground when its height is zero. Use that value for h in the equation, and solve for d.
__
h(d) = -d²/125 +d . . . . the given equation
0 = d(-d/125 +1) . . . . . use h=0, and factor out d
This equation is satisfied by values of d that make the factors zero:
d = 0 ⇒ d = 0
-d/125 +1 = 0 ⇒ d = 125
The horizontal distance to the landing point is 125 meters.

NO LINKS!! Write the equation of the trigonometric graph. Try fractional values or π for the box next to x.
Answer:
y = 1·cos(π/3·x) +3
Step-by-step explanation:
The general form of the trig equation will be ...
y = (amplitude)·cos(2π/(period)·x) +(midline shift)
__
midlineYou have already determined correctly that the midline shift is 3 units.
amplitudeThe amplitude is the difference between the peak value (4) and the midline, so is ...
amplitude = peak - midline = 4 -3 = 1
periodThe period is the horizontal distance between corresponding parts of the graph. Here, the distance between peak values is 6 units, so the period is 6. That means the argument of the cosine function is ...
(2π)/6·x = (π/3)·x
__
The function you are looking for is ...
[tex]y=1\cdot\cos\left(\dfrac{\pi}{3}x\right)+3[/tex]
Answer:
[tex]y=\boxed{1}\: \cos(\:\boxed{1}\:x)+\boxed{3}[/tex]
Step-by-step explanation:
General form of cos periodic function:
y = A cos(B(x + C)) + D
where:
A = Amplitude (height from the center line to the peak or trough)2π/B = Period (horizontal distance between one peak and the next)C = (horizontal) Phase ShiftD = Vertical ShiftParent function → y = cos(x)
The parent function y = cos(x) has a center line at y = 0.
The center line of the new function is at y = 3, so the parent function has been shifted vertically by 3 units. Therefore, D = 3:
⇒ y = A cos(B(x + C)) + 3
The amplitude of the parent function is 1.
The amplitude of the new function is also 1. Therefore, A = 1:
⇒ y = 1 cos(B(x + C)) + 3
The parent function has a peak at x = 0.
The new function has a peak at x = 0. Therefore there has been no horizontal phase shift, so C = 0:
⇒ y = 1 cos(B(x + 0)) + 3
⇒ y = 1 cos(Bx) + 3
Finally, from inspection of the curve, the period appears to be 2π (6.28)
2π/B = 2π so B = 1
⇒ y = 1 cos(1x) + 3
Please see attached graph for reference.
The parent function is shown in blue.The dotted line is shown in grey.The new function is shown in black.5

The problem itself gives us c and a.
We have to solve for b.

1089 - 64 = 1025 = b^2
notice that we found b^2 but we are looking for b

Solve the system of equations graphically. Then classify
the system as consistent or inconsistent and the
equations as dependent or independent.
5x - y = 7
5x+6y= -7
Answer:
They are consistent and independent
Step-by-step explanation:
Consistency
If two lines have an intersection point, they are said to be consistent. For example, two parallel lines do not have an intersection and therefore they are inconsistent.
In the problem, the two lines intersect at (1, -2) so they have a unique solution and therefore consistent.
Dependency
Two lines are said to be independent if one of them cannot be written as an integer multiple of the other. Or, in other words, if the slope-intercept form of both equations have different slope and y intercept
Note: slope-intercept form of an equation is y = mx + c where m is the slope and c the y intercept
Line 1: 5x - y = 7 can be written as y = 5x - 7 which has slope +5 and y intercept -7
Line2 : 5x + 6y = -7 can be re-written as y = (-5/6)x - (7/6). This has slope -5/6 and y intercept -7/6
Since slope and intercepts of both lines are different they form a system of independent equations

x = 6
Step-by-step explanation:Equilaterals are a type of triangle where all of the sides are congruent. The angles are also all equal.
Setting Up the Equation
As stated above, all of the sides are congruent. This means that the lines must be equal to which others. Since the sides are equal, we can set them equal to each other.
AB = ACNow, we can substitute the expressions in the equation.
22x - 33 = 7x +57Solving the Equation
After we set up the equation, we can solve for x using the properties of equality. There are different orders in which this can be solved. So if you prefer to work in a different order, the answer should still be the same.
First, rewrite the equation
22x - 33 = 7x +57Next, add 33 to both sides
22x = 7x + 90Then, subtract 7x from both sides
15x = 90Finally, divide both sides 15
x = 6This gives us our final answer of 6.
Checking the Answer
If you wanted to, you can check your answer by plugging 6 into the original equation.
22(6) - 33 = 7(6) + 57Then solve the equation
99 = 99Since both sides are equal, the answer must be correct.
What are practical situations of geometric series.
Answer:
One of the practical situation of geometric series is : A ball bouncing is an example of a finite geometric sequence. Each time the ball bounces it’s height gets cut down by half. If the ball’s first height is 4 feet, the next time it bounces it’s highest bounce will be at 2 feet, then 1, then 6 inches and so on, until the ball stops bouncing
Answer:
Geometric series are seen in practical situations, most notably in those involving geometric growth or decay. If a series of numbers are formed by percentages, then it can result in a geometric sequence. Ex. compound interest (see below).
Step-by-step explanation:
A geometric series is the result of adding the terms of a geometric sequence. These sequences have a common ratio, r, which is used to find missing terms. The common ratio is found with [tex]r=\frac{a_n}{a_{n-1}}[/tex]. For example, [tex]a_1(r)=a_2, \mbox{ and } a_2(r)=a_3... \mbox{ etc.}[/tex]
Geometric sequences can be used to model practical situations, and such situation could involve geometric growth or decay.
A geometric sequence can be used to model compound interest. An example of this is [tex]A = P (1 + \frac{r}{100})^n[/tex] where the common ratio, r, of the series is equal to 1 + r/100 in the compound interest formula above.
