Answer:

5/13

Step-by-step explanation:

Since the triangles are similar, the cos F = cos C

Cos C = adjacent side/ hypotenuse

Cos C = 5/13

Cos F = 5/13

Answer:

The correct answer is,

| -8|

| 4 |

Step-by-step explanation:

It is given two matrices,

1)Let Matrix A =   5  -2

                          -6    2

2) Matrix B =       -1

                          -1

Matrix A is 2 x 2 matrix and matrix B is 2 x 1 matrix

To find the product of two matrices

A x B =    5  -2       x      -1     =   -10+2      =   -8

             -6    2              -1             6 -2            4

Answer:

advance tickets cost $20 each & same-day tickets cost $35 each

Step-by-step explanation:

Let cost of advanced ticket be x and cost of same-day ticket be y. Now we can write 2 equations and solve them simultaneously.

"The combined cost of one advance ticket and one same-day ticket is $55":

[tex]x+y=55[/tex]

and

"...40 advance tickets and 15 same-day tickets were sold. The total amount paid for the tickets was $1325":

[tex]40x+15y=1325[/tex]

We solve for x in the first equation to get x = 55 - y and substitute this into 2nd equation and solve for y:

[tex]40(55-y)+15y=1325\\2200-40y+15y=1325\\-25y=1325-2200\\-25y=-875\\y=\frac{-875}{-25}=35[/tex]

Now plugging in y = 35 into the first equation, we can solve for x:

[tex]x+y=55\\x+35=55\\x=55-35\\x=20[/tex]

Hence, advance tickets cost $20 each & same-day tickets cost $35 each

Answer:

d = b/c.

Step-by-step explanation:

Just divide both sides by c:

b = cd

b / c = cd/ c

b/c = d.

Answer:

[tex] d = \frac { b } { c } [/tex]

Step-by-step explanation:

We are given the following equation and we are to solve it for d:

[tex] b = c d [/tex]

Since we are asked to solve this equation for d and it contains all variables, it means that we need to make the variable 'd' the subject of the equation by keeping all other variables at the other side of the equation.

[tex] b = c d [/tex]

[tex]d=\frac{b}{c}[/tex]

Option 2 - [tex]-6x^3+x^2-\sqrt5[/tex]

This is a polynomial by definition.

Option 3 - [tex]8x^2+\sqrt x[/tex]

This is not a polynomial as  [tex]\sqrt x[/tex] is not considerable.

Answer:

c

Step-by-step explanation:

The correct option is c. $336.36. The previous day's closing price of  stock was:c. $336.36.

To determine the closing price of stock the previous day, we need to use the information provided in the table. The table shows the net change (Chg) in the stock price and the current closing price (Close). The net change is the difference between the current closing price and the previous day's closing price.

From the table:

- Current closing price (Close): $342.64

- Net change (Chg): $6.28

Since the net change represents the increase in the stock price from the previous day to the current day, we can calculate the previous day's closing price by subtracting the net change from the current closing price.

[tex]\[\text{Previous day's closing price} = \text{Current closing price} - \text{Net change}\][/tex]

[tex]\[\text{Previous day's closing price} = 342.64 - 6.28 = 336.36\][/tex]

Therefore, the previous day's closing price of stock was:

c. $336.36

Answer:

first...you have to split the net into three rectangles and two triangles

picture inserted

Step-by-step explanation:

step 1

triangular base area

1/2 bh = 1/2 (44 in)(64 in)

= 1/2 (2,816 sq in)

= 1,408 sq in.

2 x 1,408 sq in = 2,816 sq in.

step 2

end rectangle area

lw = (68 in)(69 in)

= 4,692 sq in

2 x 4,692 sq in = 9,384 sq in

Now find the area of the middle rectangle

lw - (69 in) (44 in) = 3,039 sq in.

then add all the areas together

2,816 + 9,384 + 3,036 = 15,236 sq in

The fabric that is required to make the tent should be B. 15,236 sq in.

triangular base area

1/2 bh = 1/2 (44 in)(64 in)

= 1/2 (2,816 sq in)

= 1,408 sq in.

Now

2 (1,408 sq in) = 2,816 sq in.

Now

end rectangle area

lw = (68 in)(69 in)

= 4,692 sq in

So,

2  (4,692 sq in) = 9,384 sq in

Now determine the area of the middle rectangle

So,

lw - (69 in) (44 in) = 3,039 sq in.

So, the fabric required is

= 2,816 + 9,384 + 3,036

= 15,236 sq in

Answer:

15 inches

Step-by-step explanation:

Suppose length of original square is L inches.

Now, to form a new square the length increases by 2.5 inches

So, new length=L+2.5 inches

Given that, perimeter of new square =70 inches.

Formula:-

        Perimeter=4*length of square

Therefore 70=4*(L+2.5)

                   70 =4 L+10

                   4 L=60

                  L=15 inches

Answer:

The original length of each side was 15 inches.

Step-by-step explanation:

In this case we have to have clear that the perimeter of square consists in the addition of the length of each one of its four sides, this is:

[tex]perimeter=a+a+a+a[/tex]

The new square has a perimeter of 70, and we have to find the original length of each side, the equation will be:

[tex]70=a+2.5+a+2.5+a+2.5+a+2.5[/tex]

[tex]70=4a+10[/tex]

We have to clear a:

[tex]a=\frac{70-10}{4} \\a=\frac{60}{4} \\a=15[/tex]

The original length of each side was 15 inches.

[tex]y = - 2(x - 2)(x - 10)[/tex]

[tex]0 = - 2(x - 2)(x - 10)[/tex]

[tex]x - 2 = 0 \\ x = 2[/tex]

[tex]x - 10 = 0 \\ x = 10[/tex]

Answer:

The zero's are x=2 and x=10

Step-by-step explanation:

y = -2(x-2) (x-10)

We want to find the zero's so we set y=0

0 = -2(x-2) (x-10)

Using the zero product property

x-2 = 0   and x-10 =0

x-2+2 =0+2     x-10+10 =0+10

x =2      x=10

The zero's are x=2 and x=10

let's recall something about a right-triangle.

it has a 90° angle, and the longest side, the hypotenuse, from the pythagorean theorem, is c² = a² + b², or namely c = √( a² + b²).

so, let's take a peek at the two smaller sides, 60 and 11, can we get the longest side from it using the pythagorean theorem?

[tex]\bf \textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2\implies c=\sqrt{a^2+b^2} \qquad \begin{cases} c=\stackrel{hypotenuse}{61}\\ a=\stackrel{adjacent}{60}\\ b=\stackrel{opposite}{11}\\ \end{cases} \\\\\\ 61=\sqrt{60^2+11^2}\implies 61=\sqrt{3600+121} \\\\\\ 61=\sqrt{3721}\implies 61=61~~\stackrel{\textit{yeap, it is}}{\checkmark}[/tex]

The given lengths of 60ft, 61ft, and 11ft can form a right triangle. This has been confirmed by applying the Pythagorean theorem, which gives equal results for both sides of the equation.

In the field of Mathematics, the formation of a right triangle with given side lengths can be verified using the Pythagorean theorem. The theorem states: If a triangle is a right triangle, then the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides, as represented by this formula: a² + b² = c².

Applying this theorem to your question, we can use the three lengths you've provided: 60ft, 61ft, and 11ft. Let's assign the longest length (considered as the hypotenuse in a right triangle) as 'c', which is 61ft in this case. The other sides 'a' and 'b' would be 60ft and 11ft.

Here's how the theorem fits: 60² + 11² = 61².

Calculating the squares gives us 3600 + 121 = 3721 for the left-hand side, and 3721 for the right-hand side as well. Since the results are equal, the given lengths can indeed form a right triangle according to the Pythagorean theorem.

The length of the bd in the given triangle is 12 cm. This is obtained by applying the Pythagoras theorem.

The Pythagoras theorem states that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse. I.e., [tex]a^2+b^2=c^2[/tex].

The triangle is perpendicularly divided into two halves looking like right-angled triangles.

The side lengths for the given triangle are bc=13 cm and ac=10 cm

The line segment bd divides the triangle into two right-angled triangles symmetrically.

So, the base ac of the given triangle is divided at the mid-point d.

Thus,

ac = ad + dc

here, d is the mid point, ad = dc

So, ad=dc=5 cm

Now, the triangle forms a right-angled triangle with sides bd, dc, and bc. Where bc is the hypotenuse.

To find the length of bd, applying the Pythagoras theorem

[tex](bc)^2=(bd)^2+(dc)^2[/tex]

⇒ [tex](13)^2 = (bd)^2 + (5)^2[/tex]

⇒ [tex]169 = (bd)^2 +25[/tex]

⇒ [tex](bd)^2 = 169 - 25[/tex]

⇒ [tex](bd)^2 = 144[/tex]

∴ bd = 12 cm

Therefore, the length of the bd is 12 cm.
