Could someone please help me with this
makvit [3.9K]

Answer:

4√3 cm^2

Step-by-step explanation:

30 60 90 right triangle

The ratio of short leg : long leg :   hypo. = x : x√3 :2x

Given Hypo BC = 4 = 2 * 2

so Long leg = 2√3

Area of ABC = 1/2 (b)(h)

= 1/2 (4)(2√3)

= 4√3

Answer

4√3 cm^2

Perimeter = 3 x 4 = 12 cm (you asked from other, so I answered for you as well)

1. Write the slope-intercept form of the equation of each line given the slope and y-intercept.
AleksAgata [21]

Answer:

4b. −6x + y = −4

4a. 7x + 4y = −12

3b. y = ½x + 3

3a. y = −6x + 5

2b. y + 2 = −⅔(x + 3)

2a. y - 3 = ⅘(x - 5)

1b. y = -x + 5

1a. y = 5x - 3

Step-by-step explanation:

4.

Plug the coordinates into the Slope-Intercept Formula first, then convert to Standard Form [Ax + By = C]:

b.

2 = 6[1] + b

6

−4 = b

y = 6x - 4

-6x - 6x

_________

−6x + y = −4 >> Standard Equation

a.

4 = −7⁄4[-4] + b

7

−3 = b

y = −7⁄4x - 3

+7⁄4x +7⁄4x

____________

7⁄4x + y = −3 [We do not want fractions in our Standard Equation, so multiply by the denominator to get rid of it.]

4[7⁄4x + y = −3]

7x + 4y = −12 >> Standard Equation

__________________________________________________________

3.

Plug both coordinates into the Slope-Intercept Formula:

b.

5 = ½[4] + b

2

3 = b

y = ½x + 3 >> EXACT SAME EQUATION

a.

−1 = −6[1] + b

−6

5 = b

y = −6x + 5

* Parallel lines have <em>SIMILAR RATE OF CHANGES</em> [<em>SLOPES</em>].

__________________________________________________________

2.

b. y + 2 = −⅔(x + 3)

a. y - 3 = ⅘(x - 5)

According to the <em>Point-Slope Formula</em>, <em>y - y₁ = m(x - x₁)</em>, all the negative symbols give the OPPOSITE TERMS OF WHAT THEY REALLY ARE, so be EXTREMELY CAREFUL inserting the coordinates into the formula with their CORRECT SIGNS.

__________________________________________________________

1.

b. y = -x + 5

a. y = 5x - 3

Just write out the Slope-Intercept Formula as it is given to you.

I am joyous to assist you anytime.

Let ​f(x)= -5x+6. Find and simplify ​f(3n−5​). <br><br> f(3n-5)= ?
IRINA_888 [86]
We know that our function is f(x)=-5x+6; the only thing we need to find f(3n-5) is replace x with (3n-5) in our original function:
f(x)=-5x+6
f(3n-5)=-5(3n-5)+6

Now, lets simplify our function:
f(3n-5)=-15n+25+6
f(3n-5)=-15n+31

After simplify our function, we can conclude that f(3n-5)=-15n+31

You are competing in a race. The table shows the times from last year's race. You want your time to be last year's median time w
olasank [31]

Answer:

  28 ≤  x ≤40

Step-by-step explanation:

Arrange the data from the smallest to the largest

26, 27, 28,32, 32, 33, 35, 36, 38, 40,42,48

Identify the median value

26, 27, 28,32, 32,<u> 33, 35</u>, 36, 38, 40,42,48

Getting the median

(33+35)/2   =  68/2  = 34 minutes

You want your time to be last year's median time with an absolute deviation of at most 6 minutes

This mean ±6 minutes, hence this will be 34 ± 6

34+6=40  and 34-6=28

The inequality will be    28 ≤  x ≤40
