Answer:
Step-by-step explanation:
D.The left end goes up and the right end goes down because this is a first order function
The end behavior of the function f(x) = -2(x - 2)^5 is that the left end goes up and the right end goes down. This is determined by the odd degree and negative leading coefficient of the function.
Explanation:The end behaviors of a function can be determined by looking at the highest degree term, also known as the leading term. In this case, for the function f(x) = -2(x - 2)^5, the highest degree is odd (5), and the coefficient, -2, is negative.
Odd degree with a negative leading coefficient means that the end behaviors of this function will be: as x approaches negative infinity (moves left), the function values will go toward positive infinity (up), and as x approaches positive infinity (moves right), the function values will go toward negative infinity (down).
So the correct option here is: D. The left end goes up; the right end goes down.

The radius of a fishing line is 2.5*10^-4 foot. Write this number in standard form. Then write your answer using inches.
To write the radius of the fishing line in standard form, it is 0.00025 foot. In inches, the length is 0.003 inches.
Explanation:The radius of the fishing line is given as 2.5*10^-4 foot. To write this number in standard form, we first need to convert it into decimal form.
To do this, we move the decimal point four places to the left, since the exponent is negative. This gives us 0.00025.
Therefore, the number in standard form is 0.00025 foot.
To convert this into inches, we know that there are 12 inches in a foot. So, we multiply the length in feet by 12 to get the length in inches.
Therefore, the length of the fishing line in inches is 0.00025 foot * 12 inches/foot = 0.003 inches.
10. An archery arrow is shot with a speed of 45 m/s at an angle of 10°. How for
horizontally can the arrow travel before hitting a target at the same height
from which it was released?
Answer:
The horizontal distance travelled by an arrow is 70.6 m.
Step-by-step explanation:
Given : An archery arrow is shot with a speed of 45 m/s at an angle of 10°.
To find : How for horizontally can the arrow travel before hitting a target at the same height from which it was released?
Solution :
The expression for the range of the projectile motion is
[tex]R=\frac{V^2\sin 2\theta}{g}[/tex]
Where, the velocity of an arrow is V = 45 m / s
The angle of release of an arrow is [tex]\theta=10^\circ[/tex]
The acceleration due to gravity is g =9.81 m/s²
Substitute the values,
[tex]R=\frac{45^2\sin 2(10)}{9.81}[/tex]
[tex]R=\frac{2025\sin (20)}{9.81}[/tex]
[tex]R=70.6\ m[/tex]
Therefore, the horizontal distance travelled by an arrow is 70.6 m.
The arrow travels approximately 70.9 meters.
To determine how far the arrow travels horizontally, we need to break the initial velocity into horizontal and vertical components and use the projectile motion equations.
Step-by-step solution:
Determine the horizontal and vertical components of the initial velocity:The arrow travels approximately 70.9 meters horizontally before hitting a target at the same height from which it was released.
Nine out of twelve members of a jury are over 35 years old. What percent of the jury is not over 35?
Answer:
75% are so 15%
Step-by-step explanation:
To determine the percentage of the jury not over 35 years old, divide the number of jurors not over 35 by the total number of jurors (3/12) and then multiply by 100, resulting in 25 percent.
Explanation:If nine out of twelve jurors are over 35, then three out of twelve jurors are not over 35. To find out what percentage of the jury is not over 35, we use the following calculation:
Divide the number of jurors who are not over 35 by the total number of jurors. So we get 3/12.To convert this fraction into a percentage, multiply by 100. So we get (3/12) × 100.Perform the multiplication: 3 × 100 = 300, then divide by 12: 300 / 12 = 25.Therefore, 25 percent of the jury is not over 35 years old.
How do yo solve (x-5)(-3)=18
Answer:
x = -1
Step-by-step explanation:
Given
(x - 5)(-3) = 18
Expand the bracket
x X -3 -5 x -3 = 18
-3x + 15 = 18
Subtract 15 from both sides
-3x + 15 - 15 = 18 - 15
-3x = 3
Divide both sides by -3
-3x/-3 = 3/-3
x = -1

Enter your answers in the boxes to correctly complete this statement.
The decimal point should be moved ___ places to the right because there are ___ zeros in 10 to the power of 5.
Decimal point moved 5 places to the right, since 10⁵ has 5 zeros in it.
Step-by-step explanation:
52.48 is multiplied by 10 to the power of 5, that is 100, 000, we will get ,
[tex]52.48 \times 10^{5}=5248000.00[/tex]
When 52.48 is multiplied by 100,000, we will get 5248 followed by 5 zeros, 524800000.
Now we have to count the decimal point from left to right, so we will get 5248000.00, zeros after the decimal point has no value.
The decimal point should be moved _5__ places to the right because there are _5__ zeros in 10 to the power of 5.

a picture frame holds a 4-in. by 6-in. photograph. the frame adds a border x inches wide around the three sides of the photo. on the fourth side the frame forms a border that is 3x - 0.5 in. wide. the combined area of the photograph and the frame is 80.5 in^2. write a quadratic equation for the combined area. Then use the quadratic equation formula to find x
Answer:
1. The quadratic equation is 3x² +17.5x - 58.5 = 0
2. The values of x are 2.38 and -8.21, but we only take 2.38 for our problem.
3. The dimensions of the combined area are approximately 6.38 inches and 12.64 inches.
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Photograph dimensions = 4 inches * 6 inches
Frame dimensions = x inches * 3x - 0.5 inches
Area of the combined area of the photograph and the frame = 80.5 inches²
2. Write a quadratic equation for the combined area. Then use the quadratic equation formula to find x.
One side of the combined area of the photograph and the frame = 4 + x inches
Second side of the combined area of the photograph and the frame = 6 + 3x - 0.5 inches
Now, we can write the quadratic equation this way:
Combined area of the photograph and the frame = One side * Second side, replacing with the values we know:
80.5 = (4 + x) * (6 + 3x - 0.5)
80.5 = (4 + x) * (5.5 + 3x)
80.5 = 22 + 5.5x + 12x + 3x²
3x² +17.5x - 58.5 = 0
Using the quadratic formula, where, a = 3, b = 17.5 and c = - 58.5, we have:
x = (-b +/- √b² - 4ac)/2a
x = (-17.5 +/- √17.5² - 4 * 3 * -58.5) 2 * 3
x = (-17.5 +/- √306.25 + 702)/6
x = (-17.5 +/- √1,008.25)/6
x = (-17.5 +/- 31.75)/6
x₁ = 14.25/6 = 2.38
x₂ = -49.25/6 = -8.21
We took the value of x₁ because x₂ is negative and we can't have a negative value for the length or the width, therefore:
80.5 = (4 + x) * (5.5 + 3x)
Replacing x, we have:
80.5 = (4 + 2.38) * (5.5 + 3 * 2.38)
80.5 = 6.38 * 12.64
80.5 ≅ 6.38 * 12.64

[tex]\angle 6 =45\°[/tex]
Step-by-step explanation:
Given:
m∠1 = 135°
Lines b and c are parallel.
To Find:
m∠6 = ?
Solution:
Linear Pair:
A linear pair of angles is formed when two lines intersect.
Two angles are said to be linear if they are adjacent angles formed by two intersecting lines.
The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
Example
∠ 1 and ∠ 2 ∠ 1 and ∠ 3 ,etc
[tex]\angle 1 + \angle 3 = 180\°[/tex]
Substituting the values we get
[tex]135 + \angle 3 = 180\\\\\angle 3 = 180-135=45\°[/tex]
Now,
Lines b and c are parallel. .Given
When Two lines are Parallel Alternate interior angles are equal
∠ 3 and ∠ 6 are Alternate Interior angles
[tex]\angle 3 = \angle 6[/tex]
But [tex]\angle 3 =45\°[/tex]
[tex]\angle 6 =45\°[/tex] ...Transitive Property
Therefore,
The Measure of angle 6 is

the cube and rectangular prism have the same base area and height. how can you use this information to determine the volume of the pyramid?
The given pyramid's volume is 40 cubic units.
Step-by-step explanation:
Step 1:
It is given that base areas of the pyramid and the prism are the same. The height is also equal.
The rectangular prism's height is 15 units so as per the given question, the height of the pyramid is also 15 units.
