Pythagorean Theorem: hypotenuse= leg^2×leg^2

Answer:

v=0.15 miles per second

Step-by-step explanation:

The distance it travels in miles, d, is related to the time in seconds, t, by the equation d=0.15t.

We need to find how fast is it flying.

Differentiate the given equation wrt t.

[tex]\dfrac{dd}{dt}=\dfrac{d}{dt}(0.15t)\\\\\because \dfrac{dd}{dt}=\text{velocity(v)}\\\\v=0.15[/tex]

It means the velocity of the airplane is 0.15 miles per second.

Answer: y = 1/5x+5

Step-by-step explanation: Slope intercept form is y = mx+b, where m is the slope, and b is the y intercept. Substitute accordingly.

Answer:

4

Step-by-step explanation:

And let the missing number be x

We can solve using Algebra

11x - 10 = 34

11x = 34 + 10

11x = 44

x = 44/11

x = 4

For verification:

4(11) - 10 = 34

44 - 10 = 34

34 = 34

Hence, Proved

Answer:

Answer:

[tex]x=3[/tex]

[tex]y=1[/tex]

Step-by-step explanation:

We can subtract the first equation from the second to find the value of [tex]y[/tex], although we can also do this vice versa.

[tex]x-x=2y+1-y-2[/tex]

[tex]y-1=0[/tex]

[tex]y=1[/tex]

Now, we can use substitution to solve for [tex]x[/tex]:

[tex]x = y+2[/tex] (pick any equation for substitution)

[tex]x=1+2[/tex]

[tex]x=3[/tex]

Hope this helps :)

Answer:

The equation of line in the form of Ax + By = C is: [tex]\mathbf{4x+y=-17}[/tex]

Step-by-step explanation:

We need to find the equation of line, with the given slope passes through the given point.

Slope m = -4

Point: (-2,-9)

We need to find slope and y-intercept of the line.

The slope of line is given m = -4

Now, we need to find the y-intercept

Using the point (-2,-9) and slope m = -4, we can find y-intercept

The formula used will be: [tex]y=mx-b[/tex]

Putting values of: y= -9, x =-2 and m = -4

[tex]y=mx+b\\-9=-4(-2)+b\\-9=8+b\\b=-9-8\\b=-17[/tex]

So, y-intercept b = -17

Now, the equation of required line having slope m = -4 and y-intercept b = -17 is:

[tex]y=mx+b\\y=-4x-17[/tex]

Writing equation in required form i.e. of Ax + By = C

[tex]y=-4x-17\\4x+y=-17[/tex]

So, the equation of line in the form of Ax + By = C is: [tex]\mathbf{4x+y=-17}[/tex]

Answer: 2%

Step-by-step explanation:

As the loan was only for a year at simple interest, find out how much of $2,000, $40 is:

= 40/2,000

= 2%

Step-by-step explanation:

given

3y + 6x = - 3

writing in slope intercept form y = mx + c

3y = - 3 - 6x

y = -3/3 - 6x /3

y = - 1 - 2x

y = -2x - 1

m = - 2

c = - 1

Hope it will help :)

Answer:

The percentage increase is 78.72%

Step-by-step explanation:

Here, we want to calculate a percentage increase

We proceed to use the mathematical relation as follows;

Percentage increase = (new value - old value)/old value * 100%

new value is value in 2011 = 252

old value is value in 2006 = 141

Substituting these values, we have;

(252-141)/141 * 100%

= 111/141 * 100%

= 78.72%

Answer:

  Triangle Angle Sum

Step-by-step explanation:

Corresponding angles applies to parallel lines crossed by a transversal, or to angles in similar figure. The term has no meaning in this geometry.

Supplementary angles refers to a pair of angles that have a sum of 180°. Usually these are seen in quadrilaterals and figures involving parallel lines. The term has no meaning in this geometry.

The Pythagorean theorem relates side lengths in a right triangle. It has no utility in this geometry. Here we're concerned with angles, not sides.

__

The theorem useful for finding x is the Triangle Angle Sum theorem, which tells you the sum of angles in a triangle is 180°. That theorem lets you write a linear equation involving x, so that x can be found.

_____

  (3x -2) +(x +8) +(2x +3) = 180

  6x +9 = 180

  x = 171/6 = 28.5°

The three angles are 36.5°, 60°, 83.5°.

Step-by-step explanation:

9 can be written as a product of 3 and 3

9=3×3 ( because 3 is a prime no. as it has two different factors ,i.e. 3 and 1)

Step-by-step explanation:

so we start using repeated division to find 9 as a product of primes.

First divide 9 by the smallest prime factor it has.

9/3=3

Next, divide the result (3) by the smallest prime factor it has.

3/3=1

Once you reach 1, which we just did, you have finished.

Now collect all the results you have.

3x3

There you go, 9=3x3, as a product of primes.

or 3^2, if you want to write it in index notation.

This works for any integer.

Answer:  think its A because that little square box is a angle of a angle triangle.i won't get my answer right. cool

Step-by-step explanation: i can't explain this

Answer: a = 8;  b = 15;  c = 17

Step-by-step explanation:

c = b + 2  and c = 2a + 1

b = c − 2 and a =  [tex]\frac{c-1}{2}[/tex]

​

c² = b² + a²  

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

[tex]c^{2}= \frac{4 (c-2)^{2}+(c - 1)^{2} }{4}[/tex]

[tex]4c^{2}={4 (c^{2} + 4 -4c)+c ^{2} + 1-2c[/tex]

[tex]4c^{2}={4 c^{2} + 16 -16c)+c ^{2} + 1-2c[/tex]

[tex]c^{2}-18c+17=0[/tex]

[tex]c(c -17)-1(c-17)=0[/tex]

​[tex](c -1)(c-17)=0[/tex]

c = 1 or c = 17

If c = 1 then b = 1 - 2 = -1, that's not possible

So x = 17

b = 17 - 2 = 15

a = [tex]\frac{17-1}{2} = 8[/tex]

Length sides of the triangle are 17 cm, 15 cm and 8 cm.

I saw some of this on a site but I want to make sure its correct so we're gonna apply the pythagorean theory and see if its correct.

[tex]a^{2} + b^{2} = c^{2} \\8^{2} + 15^{2} = 17^{2} \\64 + 225 = 289\\289 = 289\\[/tex]

This shows that this is correct.

Hope this helped! Again, some of this was from a site, not from me.

Hello,

the above question requires more information for anyone to be able to answer.

In the abscence of that, the total weight of the two heaviest peaches can be obtained by simply summing the individual weights of the two heaviest peaches.

If for instance there are 13 peaches and the two heaviest peaches weight 5Kg and 5.5 kg respectively, the weight of the two would translate to the following:

Step-by-step explanation:

5 +5.5= 10.5Kg

Answer:

That's what pops up, on a scratch

Step-by-step explanation:

Given

k = - 2

Now evaluating

√- 72 * - 2

= √ 144

= √ ( 12)²

= 12

Hope it will help you :)❤

The evaluated solution of √-72k for k = -2 is 12.

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operation is called the arithmetic operator.

Operators which let do a basic mathematical calculation

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

Given expression as :

⇒ √-72k

And k= -2

To Evaluate the expression

Now Substitute the value of k= -2 in the expression

⇒ √- 72 × - 2

⇒ √ 144    [√ 144 = 12]

⇒  12

Hence, the evaluated solution of √-72k for k = -2 is 12.
