Answer:

The answer is B:8

Step-by-step explanation:

because when you line up the numbers in order

5 6 7 8 11 11 15

The middle number is 8

We need to simpify the given expression. The given expression to us is ,

Given Expression :-

[tex]\sf\implies \dfrac{ cos^2\theta -1}{4 \ sin^2\theta }[/tex]

Using Identity :-

[tex]\sf\implies \red{ sin^2\theta + cos^2\theta = 1}[/tex]

So that :-

[tex]\sf\implies - sin^2\theta = cos^2\theta -1[/tex]

We have :-

[tex]\sf\implies \dfrac{ cos^2\theta -1}{4 \ sin^2\theta } \\\\\sf\implies\dfrac{ - sin^2\theta}{4sin^2\theta}=\boxed{\sf -\dfrac{1}{4}} [/tex]

Hence the required answer is -1/4.

Step-by-step explanation:

Answer:

10 meters wide

Step-by-step explanation:

Perimeter = (2L + 2W)

(2(13) + 2W) = 46 - 26 = 2(W)

20 = 2W

20/ 2 = 10

w = 10

Answer:

5.2 = 0.5x + 1.9y

Step-by-step explanation:

In this case "standard form" signifies an equation resembling Ax + By = C.

Adding 0.5x to both sides results in  5.2-0.5x + 0.5x = 1.9y​ + 0.5x, or

5.2 = 0.5x + 1.9y, which is in "standard form."

Answer:

A. 50, 48, 14.

Step-by-step explanation:

The measurements of a right triangle have to satisfy the Pythagorean Theorem, or a² + b² = c².

a² + b² = c²

14² + 48² = 50²

196 + 2304 = 2500

2500 = 2500

So the first answer, 50, 48, 14, could be the measurements of a right triangle.

remember that the circumference of a circle is 2πr

so 3.15x8 and then multiply by two

Answer:

200.96 ft²

Step-by-step explanation:

Step 1: Define/formula

To find the area of a circle, multiply the radius by itself twice, then multiply the product by pi.

[tex]a=\pi r^2(3.14*radius*radius)[/tex]

Step 2: Solve

According to the word problem, the radius is 8.

From here, we plug the numbers into the formula.

[tex]\pi 8^2(3.14*8*8)=200.96ft^2.[/tex]

Step 3: Conclude

Therefore, the area of this circle is 200.96 ft.²

Answer:

a) 184cm³  b) 15.3cm³

Step-by-step explanation:

A) Vol. of block of cheese= L×B×H= 8cm×4cm×6cm= 192cm³

    Piece of cheese cut out= S×S×S= 2cm×2cm×2cm= 8cm³

    Remainder= 192cm³ - 8cm³ = 184cm³

B) Remainder = 184cm³ is cut into 12 equal pieces

   Each pieces = 184cm³ ÷ 12 = 15.3cm³

Answer:

The temperature in degrees Celsius is 165

Step-by-step explanation:

As given

The conversion formula of Fahrenheit to Celsius is

(°F − 32) × 5/9 = °C

Where

F = temperature in Fahrenheit

Substituting the given values, we get -

[tex](329 -32)*\frac{5}{9} \\297 * \frac{5}{9}\\33*5\\165[/tex]

The temperature in degrees Celsius is 165

Answer:

Square

Step-by-step explanation:

Area of triangle = 1/2 * b * h

= 1/2 * 15 * 25

= 187.5 ft²

Area of square = side * side

= 14 * 14

= 196 ft²

Comparing both areas, it is clear that square have a larger area.

Answer:

1 and -3

Step-by-step explanation:

To solve for the roots (x-1)(x+3) set x-1 to = 0 and solve for x. Same thing for x+3.

Answer:

1, and -3

Step-by-step explanation:

So when looking for roots, we take our quadratic equation that is in factored form, and set each partheasese to 0:

x-1=0 and x+3=0

Now just subtract and add the -1 and +3 to both sides:

x=1 and x=-3

These are your 2 answers for the quadratic.

Hope this helps!

Answer:

its c on edge 2021

Step-by-step explanation:

The function of graph is

f(x) = { x²                   , x < 1

         1/3x+ 2/3        , x > 1

In mathematics, a function is an expression, rule, or law that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

For first part of graph we have the equation of parabola as

y = a (x- h)² + k

At origin, h= 6 and k= 0

y = ax²

and, Passing through the point (1, 1)

1 = 1 (a)

a= 1

So, the equation first is y= x².

Now, for second part using slope intercept form

y= mx+ b

As, Passing through (1, 1) and (4, 2)

(y- 1) = (2-1)/ (4-1) (x- 1)

y-1 = 1/3 (x-1)

y - 1 = 1/3 x - 1/3

y - 1/3 x = -1/3 + 1

y - 1/3x = 2/3

y= 1/3x + 2/3

So, the function of graph is

f(x) = { x²                   , x < 1

         1/3x+ 2/3        , x > 1
