Answer:

-10

Step-by-step explanation:

The required value of x is -1 when f(x) = –3 for the given function. The correct answer is option (D) -1.

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

The given table represents the function f(x).

x      f(x)

-4   -66

-3   -29

-2    -10

-1      -3

0     -1

1     6

We are given a table representing the function f(x) and we need to find the value of x when f(x) = –3.

From the given table, we can see that when x = –1, f(x) = –3. Therefore, the answer is -1.

Hence, the correct option is:

(D) -1

Answer:

[tex]A(t)=-1.8t-4.5[/tex]

Step-by-step explanation:

Mr.Mole's digging can be described by a linear model of general equation:

[tex]A(t)=m*t+c[/tex]

Where "m" is the rate at which he descends. Note that since the function A(t) measure his altitude relative to the ground, the rate "m" must be negative.

[tex](m=-1.8)[/tex]

[tex]A(t)=-1.8*t+c[/tex]

The constant "c" is his starting position. To find this value, assign the given data at t = 5 min to the equation above

[tex]-13.5=-1.8*5+c\\c=-4.5m[/tex]

Therefore, the function A(t) is described by the following formula:
[tex]A(t)=-1.8t-4.5[/tex]

1) geometric sequence

2) geometric sequence

3) arithmetic sequence

Step-by-step explanation:

First two sequences are geometric sequences

The geometric sequences are  sequences where each term is made by multiplying the preceding term by the same value

In here the first sequence is multiplied by 4

the second one is multiplied by -3

The third one however is set by adding 5 to the number each time

So the third one is an arithmetic sequence

Step-by-step explanation:

40 increases to 56.

To find the percent increase:

Subtract the increased value from the original value.

Divide the difference by the original value.

Multiply the quotient by 100 to represent the percent.

Solve:

[tex]56 - 40 = 16[/tex]

[tex]16 \div 40 = 0.4[/tex]

[tex]0.4 \times 100 = 40[/tex]

There's a 40% increase.

2a = 8

/2   /2

a = 4

Hope this helps!

Answer:

a=4

Step-by-step explanation:

We need to find a way to get (a) alone on one side.
first, we will subtract 7 from 15 to get 8.
Next, We will divide 8 by 2. to get 4

your work should look like this.
2a+7=15
2a=15-7
2a=8
a=8/2
a=4

Recall the half-angle identity,

cos²(x/2) = (1 + cos(x))/2

This means

[tex]\cos^2\left(\dfrac12 \arccos\left(-\dfrac{12}{13}\right)\right) = \dfrac{1 + \cos\left(\arccos\left(-\frac{12}{13}\right)\right)}2 = \dfrac{1 - \frac{12}{13}}2 = \boxed{\frac1{26}}[/tex]

Answer:

-3.5 14

Step-by-step explanation:

2y=-7x+28

y=-3.5x+14

Answer:

Y-intercept = (0, 14) and Slope = -7/2

Step-by-step explanation:

7x + 2y - 15 = 13

2y = -7x + 28

y = -7/2x + 14

Slope = -7/2

Y-intercept = (0, 14)

To find a linear question, we must have two points on the line and we must know the slope.

Let us choose two points at random:

    (-6,12)    and    (-5,14)

Now let us find the slope of the linear line:

 [tex]m = \frac{y2-y1}{x2-x1} =\frac{14-12}{-5--6} = 2[/tex]

   So the slope is 2.

Now let us set up the equation which now requires only one point and the slope

      let us use the point (-6,12) and the slope of 2

      [tex]y-12 = 2(x+6)\\y = 2x +12 +12\\y= 2x +4[/tex]

So the linear line is y = 2x + 4.

The radius of circle is 3/17 1/2 inhces whose diameter is 635 inch.

We have,

The diameter of circle is 635 inches.

Also, we know that the radius of circle is half of the diameter.

So, r= d/2

Then, the radius of circle is

= 635/ 2

= 317 1/2

Answer:

A 61377

B 87405

Step-by-step explanation:

If sum of the digits of a number is divisible by 3, then that number is also divisible by 3.

Option A:

Given number is: 61377

Sum of the digits = 6+1+3+7+7 = 24

24 is divisible by 3, hence 61377 is also divisible by 3.

Option B:

Given number is: 87405

Sum of the digits = 8+7+4+0+5 = 24

24 is divisible by 3, hence 87405 is also divisible by 3.

Option C:

Given number is: 30898

Sum of the digits = 3+0+8+9+8 = 28

28 is not divisible by 3, hence 30898 is also not divisible by 3.

Similarly, sum of the digits of the numbers in options D, E and F are 8, 22 and 26 respectively, which are not divisible by 3, hence the numbers 6020, 29830 and 75932 are also not divisible by 3.

The area of a 2D form is the amount of space within its perimeter.The area of the compound figure is 67.5 units².

The area of a 2D form is the amount of space within its perimeter. It is measured in square units, such as cm², m², etc. To find the area of a square formula or any other quadrilateral, multiply its length by its width.

The area of the compound figure will be the sum of the different shapes and can be named as shown below.

What the problem doesn't tell you is that "this situation" is the height of the ball relative to the ground level Lisa is standing on. The ball is dropped from a height of 6 feet above that level. The variable 'h' is said to represent the drop height (in feet), so h = 6. Evaluating the expression for t=3.5 will tell the height of the ball relative to ground level after 3.5 seconds.
