Answer:

3/10

Step-by-step explanation:

Multiply 1/2 by 5 to reach 5/10 and 1/5 by 2 to reach 2/10. Then subtract 2/10 from 5/10 to achieve the answer 3/10.

Answer:

All of the them excluding f(x)=-27x+2

The required function is [tex]f(x)=-2x^2+2[/tex]. Hence, option a is correct.

Important information:

The graph has two x-intercepts (1,0) and (-1,0). It means it is a quadratic function and [tex](x-1)[/tex] and [tex](x+1)[/tex] are two factors.

[tex]f(x)=a(x-1)(x+1)[/tex]

[tex]f(x)=a(x^2-1)[/tex]         ...(i)

The graph passes through the point (0,2). Substitute [tex]x=0,f(x)=2[/tex] in the above function.

[tex]2=a(0^2-1)[/tex]

[tex]2=-a[/tex]

[tex]-2=a[/tex]

Substitute [tex]a=-2[/tex] in (i).

[tex]f(x)=-2(x^2-1)[/tex]

[tex]f(x)=-2x^2+2[/tex]

Therefore, the correct option is a.

Answer:

[tex] c = 25[/tex]

Step-by-step explanation:

Given :-

And we need to find out the value of c for which the given trinomial is a perfect square. On looking at the given expression all the terms are having positive signs before them .So we can rewrite it on the basis of ,

Identity :-

[tex]\implies (a+b)^2=a^2+b^2+2ab[/tex]

Let's try to set the equation on this Identity .

The firsr term is 9x² . We can write it as ,

[tex]\implies 9x^2=(3x)^2[/tex]

Hence the middle term here should contain 3 and 2 as their factors. Let's Break the middle term .

[tex]\implies 30x = 2.3x.5 [/tex]

Therefore in order to make the whole expression as perfect square 5² must be replaced by c . The expression would become ,

[tex]\implies 9x^2+30x + 5^2 \\\\\implies (3x)^2+2.3x.5 +5^2\\\\\implies (3x+5)^2[/tex]

Hence the value of c should be 25 .

Answer:

Width of the room = 5 meters

Step-by-step explanation:

the rectangular living room is calculated as length * width

The area is given to be equal to 40 sq. meters (area = 40 sq. meters)

Let the width = x meters

Length = X+3 meters

Area = Length * Width

40 = X * (X+3)

40 = X^2 + 3X

We solve this quadratic equation

So x = 5 or x= -8

Width  cannot be negative, so we reject x =-8

So x = 5 is the answer

Answer:

C. (0, 2)

Step-by-step explanation:

The solution to the systems of linear equations is the coordinates of the point (x, y) where both lines of the equations intercept each other on the graph given.

Thus, the lines intercept at the point where when x = 0, y = 2.

Therefore, the solution = (0, 2).

Answer: 8

Step-by-step explanation:

Arrange the data in ascending order, and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.

Rearrange 9, 9, 2, 8, 11, 6, 4 in ascending order:

2, 4, 6, 8, 9, 9, 11

The number eight appears to be in the very middle, therefore it is the median.

the highest the sum can be is 12

so 8, 9, 10, 11, and 12 are all options

2+6, 4+4, 3+5, 5+3, 6+2 - for 8

3+6, 4+5, 5+4, 6+3 - for 9

4+6, 5+5, 6+4 - for 10

5+6, 6+5 - for 11

6+6 - for 12

total - 15/36 or 5/13

The equivalent expression of log₁₂(x⁴√x³) - 2(x+1)⁵ is 11/2log₁₂(x) - 2(x+1)⁵

From the question, we have the following parameters that can be used in our computation:

log 12 x^ 4 sqrt x^ 3 -2 (x+1)^ 5 ?

Express properly

So, we have the following representation

log₁₂(x⁴√x³) - 2(x+1)⁵

Evaluate the exponent

log₁₂(√x¹¹) - 2(x+1)⁵

Apply the power rule of logarithm

This gives

11/2log₁₂(x) - 2(x+1)⁵

Hence, the equivalent expression is 11/2log₁₂(x) - 2(x+1)⁵

Answer:

Area = 780 ft²

Step-by-step explanation:

Area of the shaded region = area of rectangle A + area of rectangle B

Area of rectangle A = L*W

L = 40 ft

W = 16 ft

Area of rectangle A = 40*16 = 640 ft²

Area of rectangle B = L*W

L = 10 ft

W = 14 ft

Area of rectangle B = 10*14 = 140 ft²

Area of the shaded region = 640 + 140 = 780 ft²
