Answer:233/6

Step-by-step explanation:

The time when the ball hit the ground, which is thrown from a height of 70 meters with an initial downward velocity of 10 m/s is 2.87.

A quadratic equation is the equation in which the unknown variable is one and the highest power of the unknown variable is two.

The standard form of the quadratic equation is,

[tex]ax^2+bx+c=0[/tex]

Here,(a,b, c) is the real numbers and (x) is the variable. To solve the equation for x, use the following formula,

[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

The ball's height h (in meters) after t seconds is given by the following.

[tex]h=70-10t-5t^2[/tex]

The ball is thrown from a height of 70 meters with an initial downward velocity of 10 m/s. In this case,

The time when the ball hit the ground has to be find out. The value of the height when it hit the group is zero. Put the value of h=0 in the above equation,

[tex]h=70-10t-5t^2\\0=70-10t-5t^2\\5t^2+10t-70=0\\5t^2+10t-70=0\\[/tex]

Solve the quadratic equation using the following formula,

[tex]t=\dfrac{-10\pm \sqrt{10^2-4(10)(-70)}}{2\times5}\\t=-4.87, t=2.87[/tex]

Consider positive value. Thus, the time when the ball hit the ground, which is thrown from a height of 70 meters with an initial downward velocity of 10 m/s is 2.87.

Answer:

Line d

Step-by-step explanation:

Since, transversal b is forming equal degree of angles (95°) with lines c and d.

So, line c || line d

As we know that parallel lines have same slope.

So, If the slope of line c is given, the slope of line d is also known.

Answer:

The answer is 2 561,2785 !!!

The required value is 2,556.2785 which is determined by the multiplication operation.

In mathematics, Multiplication operations perform Multiplying values on either side of the operator.

For example 4×2 = 8

The numbers are given in the question, as follows:

78.93 and 32.45

To calculate the product of 78.93 and 32.45, you can use the standard multiplication algorithm.

78.93 x 32.45

Apply the multiplication operation, and we get

2,556.2785

Thus, the required value is 2,556.2785.

Answer:

B and C

Step-by-step explanation:

Since m and n are parallel, we can call the two lines extending from the point B transversals.

[tex]m\angle{1} = 60^\circ[/tex] because they are vertical angles

[tex]m\angle{2} = 20^\circ[/tex] from the corresponding angles theorem.

[tex]m\angle{4} = 60^\circ[/tex] from the corresponding angles theorem.

[tex]m\angle{3} = 100^\circ[/tex] because angle 2 and 4 sum to 80, and [tex]m\angle{2} + m\angle{3} + m\angle{4} = 180^\circ[/tex] because it is a straight angle.

From this, we can see which ones are true.

A is false because angle 2 is 20 degrees.

B is true because angle 3 is 100 degrees.

C is true because angle 2 + angle 4 = 20 + 60 = 80 degrees.

D is false because angle 2 + angle 3 = 20 + 100 = 120 degrees.

Therefore, only B and C are true.

Answer:

24+9x=5

Step-by-step explanation:

First you need to find the least common multiple of the denominators of the fractions. In this case, it would be 12. Then, multiply the entire equation by this number.

2*12=24,

3/4*12=36/4=9,

5/12*12=60/12=5.

Using these values will give your final equation: 24+9x=5

Answer:

Step-by-step explanation:

Answer:

First we estimate the percent's. 8.5% - 10%, 18% - 20%. Then we do the equation. If you add percent's you get 30% multiply that by 40 and you get 12. Add that to you problem and you get $52.  

Step-by-step explanation:

Since the tax and gratuity were 4 and 8 dollars you can just add those up to the 40, but I did it another way.

This is the sample response if you want a better explanation.

The gratuity is about 20% of $40, which is $8. The tax is about 10% of $40, which is $4. So, the total cost is about $40 + $8 + $4 = $52.
