Answer:

Option D is correct.

Step-by-step explanation:

We need to find the pattern in the values as the exponents increase.

First value is 1/3

if we multiply 3 with 1/3 i.e. 1/3*3 we get 1

The next value is 1 in the table.

Now, if we multiply 1 with 3 i.e. 1*3 we get 3

The next value is 3 in the table.

Now, if we multiply 3 with 3 i.e 3*3 we get 9

So, the next value is 9 in the table.

So, if we multiply 3 with the previous value we get the next value in the table.

Hence Option D multiply the previous value by 3 is correct.

Answer:

8 inches

Step-by-step explanation:

Surface area of a prism is:

S = 2A + Ph

where A is the area of the base, P is the perimeter of the base, and h is the height of the prism.

The base is a square, so A = s² and P = 4s:

S = 2s² + 4sh

Given that S = 512 and h = 12:

512 = 2s² + 4s(12)

512 = 2s² + 48s

256 = s² + 24s

0 = s² + 24s - 256

0 = (s + 32) (s - 8)

s = -32, s = 8

Since s must be positive, s = 8 inches.

Follow below steps;

To find the length of the square base of the right prism:

First, calculate the lateral surface area: 512 in² = 4s * 12 where s is the side length of the square base.

Then, solve for s: 512 = 48s, s = 512 / 48 = 10.67 in.

Therefore, the length of the square base is 10.67 inches.

Answer:

-6

Step-by-step explanation:

Let x =1

F(x)=-x^3-2x^2+7x-10

F(1) = - (1)^3 -2(1)^2 +7(1) -10

     = -1 -2 +7-10

    = -3+7-10

   =-6

The output of the given function F(x)=-x^3-2x^2+7x-10 when x equals 1 is -6. We substituted x=1 into each term to calculate this.

The given function is F(x)=-x^3-2x^2+7x-10. To find the output of the function when x equals 1, you substitute '1' in place of 'x' in the equation. So let's calculate:

Now, add all the results together: -1 - 2 + 7 - 10 = -6. Therefore, when x equals 1, the output of the function F(x) is -6.

EXPLANATION

The given function is;

[tex]f(x) = 3 {x}^{3} + 9 {x}^{2} - 1[/tex]

We take the first derivative to get:

[tex]f'(x) = 9 {x}^{2} + 18x[/tex]

At turning point f'(x)=0

[tex] 9 {x}^{2} + 18x = 0[/tex]

[tex] 9x(x + 2) = 0[/tex]

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

We take the second derivative to get

[tex]f''(x) = 18x + 18

[/tex]

[tex]f''(0) = 18(0) + 18 = 18 \: > \: 0[/tex]

Relative minimum occurs at x=0

[tex]f''( - 2) = 18( - 2)+ 18 = - 18 \: < \: 0[/tex]

Answer:

f(x) = x + 13

Step-by-step explanation:

Given f(x) then f(x) + c represents a vertical translation

• If c > 0 then vertical shift up ↑ of c units

• If c < 0 then vertical shift down ↓ of c units

here c = + 13, hence

f(x) = x + 13

Let the base = x

Then the height would be 2x ( twice the length of the base.

Now using the given formula you get:

25 = 1/2 * 2x *x

Multiply 2x by 1/2:

1/2 * 2x = 2x/2

25 = 2x/2 * x

2x/2 = 1x, now you have:

25 = x *x

Multiply x by x:

25 = x^2

Take the square root of both sides:

x = √25

x = 5

Answer:

2520

Step-by-step explanation:

7×6×5×4×3 = 2520

Imagine □□□□□

For the 1st □, there are 7 choices

For the 2nd □, there are 6 choices (since 1 out of the 7 numbers is already used)

For the 3rd □, there are 5 choices (since 2 out of the 7 numbers are used)

And so on...

The total number of 5-digit numbers that can be formed with the digits 1 to 7, without repetition, is 2520.

Your question pertains to the concept of permutations - the number of ways items can be arranged without repetition. In this case, you are considering how many 5-digit numbers can be formed using the digits 1, 2, 3, 4, 5, 6, 7 without repeating any digit.

A helpful way to think about this is to think of the 5 places for our 5-digit number (i.e., _ _ _ _ _). For the first position, you have 7 choices (the digits 1 to 7) to choose from. Once you have chosen a digit, you are left with 6 choices for the second position, 5 for the third position, 4 for the fourth, and finally 3 for the fifth. So, the total number of 5-digit numbers you can form is 7 × 6 × 5 × 4 × 3 = 2520.

Answer:

The length of a leg of the triangle = 59.83 cm

Step-by-step explanation:

Points to remember

If a right angled triangle with angles 45°, 45° and 90° then the sides are in ratio 1 : 1 : √2

It is given a right angled triangle with  45°, 45° and 90° and hypotenuse = 84.6 cm

To find the length of a leg

Let 'x' be the length of each leg,

From the figure we can write,

1: 1 :  √2 = x : x : 84.6

Therefore x = 84.6/√2

 = 59.83 cm

Therefore the length of a leg of the triangle = 59.83 cm

ANSWER

59.82

EXPLANATION

The given right angle is an isosceles right triangle.

Let the length of a leg be x cm.

Then by the Pythagoras Theorem,

[tex] {x}^{2} + {x}^{2} = 84.6 ^{2} [/tex]

[tex]2 {x}^{2} = 7157.16[/tex]

Divide both sides by 2.

[tex]{x}^{2} = \frac{7157.16}{2} [/tex]

[tex]{x}^{2} = 3578.58[/tex]

Take positive square root of both sides to get,

[tex]x = 59.82123369[/tex]

Hence the length of a leg is 59.82 to the nearest hundredth.

Answer:

Solution (-2, 7)

Step-by-step explanation:

2x + 3y = 17      (1)

5x + 6y = 32    (2)

Using elimination method

Multiply (-2) to the equation (1)

-4x - 6y = -34  

Now you have 2 new equations

-4x - 6y = -34

5x + 6y = 32

----------------------------Add

x = -2

Substitute x = -2 into 2x + 3y = 17

2(-2) + 3y = 17

- 4 + 3y = 17

3y = 21

 y = 7

Solution (-2, 7)

Final answer:

The solution to the system of equations 2x + 3y = 17 and 5x + 6y = 32 using the elimination method is x = -2 and y = 7.

Explanation:

To solve the system of equations using the method of elimination, we manipulate the equations to make the coefficients of either x or y the same, and then subtract one equation from the other to eliminate that variable. Let's consider the given equations:

2x + 3y = 17 (Equation 1)

5x + 6y = 32 (Equation 2)

We can see that the coefficients of y are in the ratio of 3:6 or 1:2. To use elimination, we want the coefficients to match, so we can multiply Equation 1 by 2:

(2)(2x) + (2)(3y) = (2)(17)

4x + 6y = 34 (New Equation 1)

Now we can subtract the new Equation 1 from Equation 2:

(5x + 6y) - (4x + 6y) = 32 - 34

5x - 4x + 6y - 6y = -2

x = -2

Now that we have a value for x, we can substitute it back into one of the original equations to solve for y. Let's substitute x into Equation 1:

2(-2) + 3y = 17

-4 + 3y = 17

3y = 17 + 4

3y = 21

y = 7

The solution to the system of equations is x = -2 and y = 7.

Answer: x=8.5 y=1.5

Step-by-step explanation:

Use the second problem and get X by itself. X= 5y+1. Now plug that equation into the 1st equation.

-(5y+1) +9y =-5.

-5y-1+9y=-5.

-5y+9y= 1+5

4y= 6

Y=1.5

Now that you know what is the value of Y you can plug that into any equation.

5(1.5) +1

7.5+1

X=8.5

For this case we have the following system of equations:

[tex]-x + 9y = -5\\x-5y = 1[/tex]

We clear "x" from the second equation and replace it in the first:

[tex]x = 1 + 5y[/tex]

Substituting in the first equation:

[tex]- (1 + 5y) + 9y = -5\\-1-5y + 9y = -5[/tex]

We have similar terms:

[tex]-1 + 4y = -5[/tex]

Adding 1 to both sides of the equation:

[tex]4y = -5 + 1\\4y = -4\\y = \frac {-4} {4}\\y = -1[/tex]

3x - 7 = 2³ = 8 ( add 7 to both sides )

3x = 15 ( divide both sides by 3 )

x = 5

The required solution of logarithmic expression  log2 (3x - 7) = 3 is x = 5. Option B is correct.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
To solve for x in the equation log2 (3x - 7) = 3, we first use the definition of a logarithm to change the logarithmic form to the exponential form.

log2 (3x - 7) = 3

2³ = 3x - 7

Next, we solve for x by adding 7 to both sides of the equation:

8  + 7= 3x - 7 + 7

15 = 3x

Finally, we divide both sides of the equation by 3:

x = 5

So, the solution of log2 (3x - 7) = 3 is x = 5.
