HELP PLEASE ASAP Find the distance between A and B. (5,1) (-3,-4)

Mathematics
1 answer:
suter [353]2 years ago
4 0

Answer:

6.32

Step-by-step explanation:

The formula we use to find the distance between two points is:

\sqrt{(x_1-x_2)+(y_1-y_2)}

The x1 is -3, the x2 is 5, the y1 is -4, and lastly, the y2 is 1.

If we input these numbers in the equation, we end up with:

\sqrt{(-3-5)+(-4-1)}

= \sqrt{(-8) (-5)}

= \sqrt{40}

= 2\sqrt{10}

= 6.32455532

Rounded to the nearest hundredth is 6.32

Suppose a ball is thrown directly upward from a height of 7 feet with an initial velocity of 50 feet per second. Use the quadrat
Fittoniya [83]

Answer:

t = 3.3 seconds

Step-by-step explanation:

From the formula of vertical motion of an object under gravity we can write the equation

H = ut + \frac{1}{2} gt^{2} ....... (1)

Where u is the initial velocity (in feet per second) of throw of the object and t is time of travel in seconds and the value of g i.e. gravitational acceleration is 32 feet/sec².

Now, while a ball is thrown vertically upward with velocity 50 ft/sec from a height of 7 ft then the time of travel of the ball before reaching the ground, the equation (1) will be written as

- 7 = 50t - \frac{1}{2} \times 32 \times t^{2}

As we have selected the upward direction as positive so, gravitational acceleration,g will be negative and as the displacement is downward by 7 feet, so it will be negative.

⇒ 16t² - 50t - 7 = 0 ........ (2)

Now, applying Sridhar Acharya formula,

t = \frac{-(-50) + \sqrt{(-50)^{2} - 4(16)(-7)}}{2(16)} {Neglecting the negative root as t can not be negative}

⇒ t = 3.3 seconds {Rounded to the nearest tenth}

Scalcet8 4. 2. 26. suppose that 2 ≤ f '(x) ≤ 4 for all values of x. what are the minimum and maximum possible values of f(4) − f
ziro4ka [17]

The minimum value of f(4) - f(1) is <u>6</u>.

The maximum value of f(4) - f(1) is <u>12</u>.

In the question, we are given that, 2 ≤ f'(x) ≤ 4 for all values of x.

Taking the given inequality as (i).

We are asked to find the minimum and maximum possible values of f(4) - f(1).

We multiply (i) by dx throughout, to get:

4dx ≤ f'(x)dx ≤ 5dx.

To find this, we integrate (i) in the definite interval [4, 1] with respect to dx, to get:

\int_{1}^{4}2dx \leq \int_{1}^{4}f'(x)dx \leq \int_{1}^{4}4dx\\\Rightarrow [2x]_{1}^{4} \leq [f(x)]_{1}^{4} \leq [4x]_{1}^{4}\\\Rightarrow 2*4 - 2*1 \leq f(4)-f(1) \leq 4*4 - 4*1\\\Rightarrow 6 \leq f(4) -f(1) \leq 12

Thus, the minimum value of f(4) - f(1) is 6.

The maximum value of f(4) - f(1) is 12.

Find the sum of 3b/b 2 and 12/b 2 and express it in simplest form
alexandr1967 [171]
\frac{3b}{b^{2}} + \frac{12}{b^{2}} = \frac{3b + 12}{b^{2}} = \frac{3(b) + 3(4)}{b^{2}} = \frac{3(b + 4)}{b^{2}}
