Step-by-step explanation:

Answer:y=3x +1

Step-by-step explanation:

The interval for the given situation is  (0, 4).

Given that, height = 400 ft, initial velocity of 64 ft/s and the equation s(t) = -16t² + 64t + 400.

Initial velocity is the velocity at time interval t = 0 and it is represented by u. It is the velocity at which the motion starts. They are four initial velocity formulas: (1) If time, acceleration and final velocity are provided, the initial velocity is articulated as. u = v – at.

To find the interval in which the ball is higher than the building, solve the inequality h(t) > 400. The inequality is easily solved by subtracting 400 so the comparison is to zero, factoring the expression involving t, and identifying the time interval in which the signs of the factors are the same.

-16t² +64t +400 > 400

⇒ -16t² +64t > 0

⇒ -16t (t -4) > 0

⇒ t=0 and t-4=0

Both factors will have negative signs on the interval (0, 4).

Therefore, the interval for the given situation is  (0, 4).

Answer:

The sum of the coefficients is 85.

Step-by-step explanation:

(3x + 7)(7x + 5)
3x * 7x is 21x^2
3x*5 is 15x

7 * 7x is 49x

7 * 5 is 35

21x^2 + 15x + 49x + 35

So the answer is 21x^2 + 64x + 35

Add the coefficients: 21 + 64 = 85

Answer:

n = q/10 - (r t)/10

Step-by-step explanation:

Solve for n:

q - 14 n = r t - 4 n

Subtract q - 4 n from both sides:

-10 n = r t - q

Divide both sides by -10:

Answer: n = q/10 - (r t)/10

Answer:

Step-by-step explanation:

m∠BCD = 145°  ⇒  m∠BCA = 180° - 145° = 35°

From ΔABC:

                    m∠ABC + m∠BCA + m∠BAC = 180°

                         65° +  35° + m∠BAC = 180°

                                  m∠BAC = 180° -  100°

Answer:

7.5 centimeters

Step-by-step explanation:

The circumference is pi times the diameter

46.8/3.14=14.9

The radius is half of the diameter

14.9/2=7.45

7.45 is rounded to 7.5

Mid point of the points PQ is (₋0.3 , 3.25)

Given points are:

P(₋2 , 2.5)

Q(1.4 , 4)

midpoint of PQ = ?

A location in the middle of a line connecting two points is referred to as the midpoint. The midpoint of a line is located between the two reference points, which are its endpoints. The line that connects these two places is split in half equally at the halfway.

The midpoint calculation is the same as averaging two numbers. As a result, by adding any two integers together and dividing by two, you may find the midpoint between them.

Midpoint formula (x,y) = (x₁ ₊ x₂/2 , y₁ ₊ y₂/2)

we have two points:

P(₋2,2.5) = (x₁,y₁)

Q(1.4,4) = (x₂,y₂)

Midpoint = (₋2 ₊ 1.4/2 , 2.5₊4/2)

= (₋0.6/2 , 6.5/2)

= (₋0.3 , 3.25)

Hence we determined the midpoint of PQ as (₋0.3 , 3.25)

Answer:

19.81cm^2

Step-by-step explanation:

To solve this, you need to use Heron's formula. Heron's formula solves for the area of a triangle given 3 sides defined as a, b, and c, as well as the perimeter. In this formula, p is half of the perimeter. The formula is:

sqrt(p*(p-a)*(p-b)*(p-c))

Plugging the values into this formula gives 19.81cm^2.

Answer: OK, stay with me on this one

the image is what your graph will look like, but with 2 lines instead of one. on the bottom, mark the months. on the side, write temperatures. Then on each month for the line for A, dot the temperature it is with a connected line. (Like the line is on the image.) Then do the same for the line for city B. I'd recommend doing it in 2 different colors, and label some where else which city.

Answer:

-1075

Step-by-step explanation:

The 64th term of the arithmetic sequence -4, -21, -38, .... is -1075.

Arithmetic sequences are a set of numbers written in an order where the difference of any two consecutive term will be a constant. This constant difference between the consecutive terms is called the common difference commonly denoted by 'd'. In other words, arithmetic sequences are formed by adding or subtracting a constant number to each term.

Arithmetic sequences are also known as arithmetic progression.

Here, the given sequence is -4, -21, -38, ...

Common difference, d = (-21) - (-4) = -21 + 4 = -17

First term, a = -4

We have to find the 64th term of this sequence.

nth term of an arithmetic progression is given by the formula,

aₙ = a + (n - 1)d

a₆₄ = -4 + [(64 - 1) × (-17)]

     = -4 + [63 × (-17)]

     = -4 + (-1071)

     = -1075

Hence the 64th term of the arithmetic sequence -4, -21, -38, .... is got as  -1075.
