How do I solve this?

Answer:

  x = 26

Step-by-step explanation:

The length marked x is the hypotenuse of a right triangle with legs 10 and 24. The Pythagorean theorem can be used to find the value of x.

The Pythagorean theorem tells you the square of the hypotenuse is the sum of the squares of the legs:

  x² = 10² +24²

  x² = 100 +576 = 676 . . . . simplify

  x = √676 . . . . . . . take the square root

  x = 26

Answer:

The hypotenuse is 26 units

Step-by-step explanation:

Step 1:  Determine the value of x

Pythagorean theorem:  [tex]a^2 + b^2 = c^2[/tex]

[tex](24)^2+(10)^2=c^2[/tex]

[tex]576 + 100 = c^2[/tex]

[tex]676 = c^2[/tex]

[tex]26 = c[/tex]

Answer: The hypotenuse is 26 units

Answer:

[tex]\sec^2(\alpha)=1+\tan^2(\alpha)[/tex]

[tex]\csc^2(\alpha)=1+\cot^2(\alpha)[/tex]

[tex]\cot^2(\alpha)=\dfrac{1}{\tan^2(\alpha)}[/tex]

[tex]\begin{aligned}\sec^2(\alpha) \cdot \csc^2(\alpha) & = (1+\tan^2(\alpha))(1+\cot^2(\alpha))\\\\ & =1+\cot^2(\alpha)+\tan^2(\alpha)+tan^2(\alpha)\cot^2(\alpha)\\\\ & = 1+\cot^2(\alpha)+\tan^2(\alpha)+\tan^2(\alpha) \cdot \dfrac{1}{\tan^2(\alpha)}\\\\ & = 1+\cot^2(\alpha)+\tan^2(\alpha)+ \dfrac{\tan^2(\alpha)}{\tan^2(\alpha)}\\\\& = 1+\cot^2(\alpha)+\tan^2(\alpha)+1\\\\& = \tan^2(\alpha)+\cot^2(\alpha)+2\end{aligned}[/tex]

Answer:

E. the product of seven and the difference of b minus two

Step-by-step explanation:

7(b-2)

seven is being multiplied by the difference of b minus 2

So this can be written as the product of seven and the difference of b minus two.

Reasons its not the other answer choices

A. two subtracted from the quotient of seven divided by b would be (7/b) - 2

B. seven added to difference of b minus two would be 7 + (b-2)

C. the quotient of seven divided by b minus two would be 7/(b-2)

D. two subtracted from seven times b would be 7b - 2

Key Vocabulary:

Difference = Subtraction

Product = Multiplication

Quotient = Division

The product of seven and the difference of b minus 2

First of all the difference of 2 numbers indicates that we subtract these numbers .

For instance , here we subtract :

b - 2

so we have the difference of b minus 2

then the product means we multiply .

For instance , here we multiply 7 times the difference of b and 2 .

A number / variable before the parentheses indicates that we multiply that number times the parentheses .

Answer:

Step-by-step explanation:

The formula for the area of a triangle gives a relationship between area, height, and base length. The problem statement gives the area, and it gives another relation between height and base length. Using these two relations, you can solve for the dimensions of the triangle.

__

The side to which the altitude is measured is called the "base" in the area formula. The altitude is called the "height." The relation between them given by the area formula is ...

  A = 1/2bh

  51 = 1/2bh . . . . . . using the given value for area

The other relation given by the problem statement is that the base is 1 less than 3 times the height:

  b = 3h -1 . . . . . . . base is 1 less than 3 times altitude

__

Using this second equation to substitute for 'b' in the first equation, we have ...

  51 = 1/2(3h -1)h

  102 = 3h² -h . . . . multiply by 2, eliminate parentheses

  3h² -h -102 = 0 . . . . . put in standard form

  3h² -18h +17h -102 = 0 . . . . . prepare to factor

  3h(h -6) +17(h -6) = 0 . . . . . factor pairs of terms

  (3h +17)(h -6) = 0 . . . . . . . . finish factoring

Solutions are the values of h that make these factors zero:

  3h +17 = 0   ⇒   h = -17/3

  h -6 = 0   ⇒   h = 6

We know that dimensions in a geometry problem must be positive, so the solution here is h = 6. Then b = 3h -1 = 3(6) -1 = 17. The dimensions are all in inches.

The length of the side is 17 inches; the altitude to that side is 6 inches.

Answer:

x = -7, y = -3 yup you did it right!

Step-by-step explanation:

Solve the following system:

{-2 y + x = -1 | (equation 1)

8 y - 5 x = 11 | (equation 2)

Swap equation 1 with equation 2:

{-(5 x) + 8 y = 11 | (equation 1)

x - 2 y = -1 | (equation 2)

Add 1/5 × (equation 1) to equation 2:

{-(5 x) + 8 y = 11 | (equation 1)

0 x - (2 y)/5 = 6/5 | (equation 2)

Multiply equation 2 by 5/2:

{-(5 x) + 8 y = 11 | (equation 1)

0 x - y = 3 | (equation 2)

Multiply equation 2 by -1:

{-(5 x) + 8 y = 11 | (equation 1)

0 x + y = -3 | (equation 2)

Subtract 8 × (equation 2) from equation 1:

{-(5 x) + 0 y = 35 | (equation 1)

0 x + y = -3 | (equation 2)

Divide equation 1 by -5:

{x + 0 y = -7 | (equation 1)

0 x + y = -3 | (equation 2)

Collect results:

Answer: {x = -7, y = -3

Answer:

$283.2

Step-by-step explanation:

Area of the order = Length * Width

7.02×10^3 = 1.17×10^2 * Width

7020 = 117W

W = 7020/117

W = 60feet

The perimeter of the border = 2(L+W

P = 2(117+60)

P = 2 * 177

P = 354 feet

If a border cost $0.80 per foot, 354 feet long border will cost 0.80 * 354 = $283.2

cos (theta) = √21/5

Step-by-step explanation:

4/25 + (cos (theta))^2 = 1

(cos (theta))^2 = 1 - 4/25 = 21/25

cos (theta) = √21/5

The three positive numbers whose sum is 27 will be 14, 1, and 12.

A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

Suppose the three positive numbers are x, y and z.

If the summation of numbers is 27.

⇒ x + y + z = 27 --- (1)

⇒ z = 27 - x - y

Suppose the square sum of the number be S.

∴ S = x² + y² + z²

⇒ S = x²+ y² + (27 - x - y)² --- (2)

We will optimize the function, partially differentiating it with respect to x and y, and setting dS/dx = 0 to get the minimum value of S.

2x + 2(27- x - y)(-1) = 0

2x - 54 + 2x + 2y = 0

4x + 2y - 54 = 0

y = 27 - 2x --- (3)

Differentiate partially with respect to y as

2y + 2(27 - x - y)(-1) = 0

2y - 54 + 2x + 2y = 0

4y + 2x - 54 = 0

x = 54 - 2y --- (4)

Substitute the value of y = 27 - 2x in the equation (4),

x = 12 - 2(27 - 2x)

x = 12 - 54 + 4x

4x - x = 54 - 12

3x = 42

⇒ x = 14

By substituting x = 14 in equation (3)

y =2(14) - 27

y = 28 - 27

⇒ y = 1

Substitute the values of x and y in equation (1),

14 + (1) + z = 27

z = -14+27-1

z= 12

Thus, the three positive numbers whose sum is 27 will be 14, 1, and 12.
