Answer:

match the boxes to the parts of the equations shown below

Step-by-step explanation:

$\text{slope}=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{50-34}{5-3}=\dfrac{16}{2}=8$

<h3>Right</h3>

$\text{slope}=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{2-31}{30-1}=\dfrac{-29}{29}=-1$

Simplify the imaginary number sqr -75

m_a_m_a [10]

Answer:

5i $\sqrt{3}$

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

and $\sqrt{-1}$ = i

Given

$\sqrt{-75}$

= $\sqrt{25(3)(-1)}$

= $\sqrt{25}$ × $\sqrt{3}$ × $\sqrt{-1}$

= 5 × $\sqrt{3}$ × i

= 5i $\sqrt{3}$

What is the surface area of the triangular prism

Harrizon [31]

Answer:

$surface \: a = 9 \times 5 \\ = 45ft \times 2 \\ = {90}^{2} ft\\ surface \: b = \frac{1}{2} bh \\ = \frac{1}{2 } \times 6 \times 4 \\ = 3 \times 4 \\ = 12 \times 2 \\ = {144}^{2} ft \\ = 90 + 144 \\ = {234}^{2} ft$

there are 2.54 centimeters in 1 inch. there are 100 centimeters in 1 meter.questionto the nearest meter, how many meters are in

Gre4nikov [31]

There are 7 meters in 279 inches.

There are 2.54 centimeters in 1 inch.
There are 100 centimeters in 1 meter.
The number of inches is given to be 279.
Unit conversion is a multi-step procedure that includes multiplying or dividing by a numerical factor, determining the appropriate number of significant digits, and rounding.
First of all, we need to convert inches to centimeters.
1 inch equals 2.54 centimeters.
279 inches equals 2.54*279 centimeters.
279 inches equals 708.66 centimeters.
Now, we need to convert these centimeters into meters.
Meters in 100 centimeters = 1
Meters in 1 centimeters = 1/100
Meters in 708.66 centimeters = (1/100)*708.66
Meters in 708.66 centimeters = 7.0866
Thus, there are approximately 7 meters in 279 inches.

A company uses a combination of three components- A, B and C to create three different drone designs. The first design Glider us

FrozenT [24]

Answer:

Consider the following calculations

Step-by-step explanation:

Since 1 Blimp uses 2 components of B and C each

=> choosing 2 components of B(remaining after using in other prototypes) for 1st model= 22C2

choosing 2 components of B(remaining after using in other prototypes) for 2nd model= 21C2

choosing 2 components of B(remaining after using in other prototypes) for 3rd model= 20C2

choosing 2 components of B(remaining after using in other prototypes) for 4th model= 19C2

choosing 2 components of B(remaining after using in other prototypes) for 5th model= 18C2

and choosing 2 components of C(remaining after using in other prototypes) = 24C2

Similarly for C

P(5 prototypes of Blimp created)=[(22C2 / 25C2 )*(24C2 / 25C2 )] + [(21C2 / 25C2 )*(23C2 / 25C2 )]+[(20C2 / 25C2 )*(22C2 / 25C2 )]+[(19C2 / 25C2 )*(21C2 / 25C2 )]+[(18C2 / 25C2 )*(20C2 / 25C2 )]
