Answer:

1.

[tex] \frac{n^{2} - 1 }{2} [/tex]

2.

[tex] \sqrt{29} [/tex]

Step-by-step explanation:

Area of triangle=1/2×b×h

=

[tex] \frac{1}{2} \times (n - 1)(n + 1)[/tex]

[tex] \frac{( {n}^{2} + n - n - 1) }{2 } [/tex]

[tex] \frac{ {n}^{2} - 1 }{2} [/tex]

2. Area of triangle=14

[tex] \frac{ {n}^{2} - 1 }{2} = 14[/tex]

[tex] {n}^{2} - 1 = 28[/tex]

[tex] {n}^{2} = 29[/tex]

[tex]n = \sqrt{29} [/tex]

Answer:

x= -5/2 or -5.2

Step-by-step explanation:

you know the equation: y=mx+b, so we can substitute the -3 for x, the 7 for y and the -4 for m:

7=-4(-3)+b

now solve:

7=12+b

subtract 12 on both sides:

b=-5

now what you want to do is substitute it in and solve for x:

y=-4x-5

so:

5=-4x-5,

solve:

10=-4x

x=-5/2!!!!!!!!!!!!!!

hope this helped :)

Answer:

96.5%

Step-by-step explanation:

Answer:

241250000 cars aren't diesel (Basically 96.5%)

Step-by-step explanation:

250 million = 250000000

If we are talking about the percentage of cars that aren't diesel, we have two ways of solving this. (I'm gonna solve for not just percentage but for amount too)

1. Find out the percentage that isn't diesel by subtracting 3.5% from 100% and then multiplying the answer to get the result.

or

2. We find out what 3.5% of 250 million is and then subtract that from 250 million

Now to make this short, I will do the first one.

100-3.5 = 96.5

96.5% x 250,000,000 = 241250000

Answer:

(-5,-7)

Step-by-step explanation:

Set functions equal to each other.

2x+3= -4x-27

2x+4x = -3-27

6x=-30

x= -5

f(-5) = 2(-5) +3

f(-5) =-10+3 y= - 7

g(-5) = -4(-5) -27

g(-5) =20-27 y= -7

x=-5 y=-7

(-5,-7)

Answer:

(-5,-7)

Step-by-step explanation:

Answer:

c = 5b ±sqrt(-10(b+a)+2)

Step-by-step explanation:

By using the Pythagoras theorem,

c² = a² + b²

a = b-5

b = a+5

c² = (b-5)² + (a+5)²

c² = b²-10b+25 + a²+10a+25

c² = b²-10b-10a+50

c² = b²-10(b+a)+50

c = 5b ±sqrt(-10(b+a)+2)

you really don't see this ?

this is rotated by 180 degrees around the origin.

do you see how the different points change positive from one shape to the other ?

think what happens when you rotate a disk (like a plate) with something on it. how does that something on it change is position and orientation ?

this here is the same thing. look at H and how it turns into O.

Answer:

y=0.25x-6

Step-by-step explanation:

The change in air temperature over 1.25 hours is -9.75°F

A linear equation is in the form:

y = mx + b;

where y, x are variables,  m is the rate of change and b is the initial value of y.

As a hurricane approaches, the air temperature changes −7.8°F every hour. The amount of change after 1.25 hours is:

Change = −7.8°F every hour * 1.25 hours

Change = -9.75°F

Therefore the change in air temperature over 1.25 hours is -9.75°F

Answer:

p=36

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:

p/18+7-(9)=0

Simplify p/18

(p/18+7)-9=0

7= 7/1= 7*18/18

p+7*18/18=p+126/18

(p+126)/18-9=0

9=9/1=9*18/18

(p+126)-(9*18)/18=p-36/18

p-36/18=0

p-36=0

p=36

Patterns are used to represent sequence of numbers.

The shape at the 50th position is a triangle

The pattern rule is given as: square, triangle, circle, oval.

The number of shapes (n) is given as:

[tex]n =4[/tex]

So, the 50th shape is calculated using the following absolute operator

[tex]Shape = 50\%4[/tex]

i.e. divide 50 by 4, and take note of the remainder.

When 50 is divided by 4, the remainder is 2

So, we have:

[tex]Shape =2[/tex]

This means that, the shape at the 50th position is the same shape at the 2nd position.

Hence, the shape is triangle
