How and his friends bought stickers for $1.25 each and will mark them up 180%. What will they sell the tickets for?

Answer:

The correct answer is C: Y = -1/2x - 4.The slope of the given line is -1/2, so any line that is parallel to it will have the same slope. In order to find the equation of a line with the same slope that passes through the point (2, -5), we can use the point-slope form of the equation of a line.The point-slope form of the equation of a line is:y - y1 = m(x - x1)where m is the slope of the line, and (x1, y1) is a point on the line.In this case, we can plug in the values m = -1/2, x1 = 2, and y1 = -5 to get:y + 5 = -1/2(x - 2)Solving for y, we get:y = -1/2x - 4Therefore, the equation of the line that is parallel to the given line and passes through the point (2, -5) is Y = -1/2x - 4.

Applying the definition of the median of a triangle, the length of AO is calculated as: 14 units.

The median of a triangle is a line segment that joins the midpoint of a side of a triangle and the opposite vertex to the side.

There are three medians in a triangle, and the three of them intersect at a point inside the triangle. This point of intersection is known as the centroid.

According to the centroid theorem of a triangle, the length from the vertex to the centroid is two-third of the length of a median.

Thus, the figure shows that triangle ABC has three medians, BL, AM, and CK, which intersect at point O. This means the centroid of the triangle is point O.

By implication, it means that:

Length of AO = 2/3 * (length of AM)

Plug in the value of AM:

Length of AO = 2/3 * (21) [centroid theorem]

AO = 2 * 7

AO = 14

The equation of the line would be y = (-3/4)x + 5.

What is the slope-point form of the line?

For the line having slope "m" and the point (x1, y1) the equation of the line passing through the point (x1, y1) having slope 'm' would be

                      y - y1 = m(x - x1)

The given equation is [tex]y=-\frac{3}{4}x-17[/tex]

The required line is parallel to the given line.

and we know that the slopes of the parallel lines are equal so the slope of the required line would be m = -3/4

And the required line passes through (8, -1)

so by using slope - point form of the line,

      y - (-1) = (-3/4)(x - 8)

      y + 1 = (-3/4)x - (-3/4)8

       y + 1 = (-3/4)x + 24/4

       y = (-3/4)x + (12/2 - 1)

       y = (-3/4)x + 5

Hence, the equation of the line would be y = (-3/4)x + 5.

A child of a parent with a mutation in collagen and displaying OI will have 50% probability of also having OI.

Osteogenesis imperfecta (OI) is an inherited or genetic bone disorder which is present at birth. It is also known as brittle bone disease. A child born with OI may have soft bones which fracture easily, bones which are not formed normally, and other problems. Signs and symptoms may range from mild to severe.

Life expectancy for OI babies vary greatly depending on OI type. Babies with Type II generally die soon after birth. Children with Type III may live longer, but mostly only until around age 10.

About 90% of OI cases are caused by autosomal dominant mutations in the type I collagen genes. Mutations in one or the other of these genes cause the body to make either abnormally formed collagen or too little collagen. Mutations in these genes cause OI Types I through IV.

since f(x) = 2×x + 1

therefore f(2.99) = 2×2.99 + 1 = 6.98 ≈ 7

The position of mailbox after 10s is equal to sum displacements is 14m.

The principle is that the slope of the line on a velocity-time graph reveals useful information about the acceleration of the object. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line).

Given velocity time graph understand in three parts.

1. first 6s mailbox have constant velocity 3m/s

the displacement covered by it = area under v-t graph(square shape)

s1=3 x 6 =18m

2. the mailbox at rest at 6-8 s.

the displacement covered by it s2=0

3. the mail returned with constant velocity 2m/s

Displacement is defined to be the change in position of an object. It can be defined mathematically with the following equation:

Displacement=Δx=[tex]x_{f} - x_{0}[/tex]

[tex]x_{f}[/tex]=refers to the value of the final position.

[tex]x_{0}[/tex]= refers to the value of the initial position.

Δx is the symbol used to represent displacement

the displacement covered by it s3 =(10-8) (-2) =-4m

the position of mailbox after 10s is equal to sum displacements=s1+s2+s3 =18+0-4=14m the displacement - time graph.

Therefore, the position of mailbox after 10s is equal to sum displacements is 14m.

Using a double integral, the area of the region is [tex]\frac{\pi}{12}[/tex].

Consider the following polar equation:

r = 8cos3[tex]\theta[/tex]

This is the process for measuring the intensity of light. Such intensity varies according to how close or far you are from LED light bulbs. Engineers use polar curves to plot the level of the intensity at any given point. In other words, a polar curve tells an engineer how LED light bulbs spread light across a room or surface.

The objective is to find the area of the region using double integral.

The sketch of the curve attached at the end of solution.

The intersection points of the curve with horizontal axis are given by,

8cos3[tex]\theta[/tex] = 0

cos3[tex]\theta[/tex] = 0

[tex]3 \theta & =\pm \frac{\pi}{2}[/tex]

Let A be the area of the curve.

The area of the loop is given by,

[tex]& A(D)=\iint_D d A \\[/tex]

[tex]& =\int_{-\frac{\pi}{6}}^{\frac{\pi}{6}} \int_0^{\cos 3 \theta} r d r d \theta \\[/tex]

There are 324 miles can Mario drive with 9 gallons of gas.

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

He can drive 18 miles on ½ a gallon of gas.

Now,

Since, He can drive 18 miles on ½ a gallon of gas.

Let the number of miles cover with 9 gallons of gas = x

So, By definition of proportion, we get;

⇒ 18 / (1/2) = x / 9

⇒ 18 × 2 = x / 9

⇒ 36 × 9 = x

⇒ x = 324 miles
