Answer:

-5/4

Step-by-step explanation:

We can use the slope formula to find the slope

m = ( y2-y1)/(x2-x1)

   = ( -3 -2)/( 3 - -1)

   = ( -3-2 ) /( 3+1)

   = -5/4

Answer:

m = -5/4

Step-by-step explanation:

The slope formula is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].

Therefore, m = -5/4.

Interest = 500

Step-by-step explanation:

Interest = [tex] \frac{p∗r∗t}{100} \\ [/tex]

p = principal amount , r = rate , t = time

Interest=[tex] \frac{10000 \times 5 \times 1}{100} \\ [/tex]

Interest = 500

Answer:

interest = RS. 500

Step-by-step explanation:

interest= 100/p*r*t

p∗r∗t

​p = principal amount , r = rate , t = time

Answer:

$68.75 cents

Step-by-step explanation:

Given the following question:

25% of 55

In order to find the answer, we must first use the formula to calculate percentages to calculate 25% of 55, then we use that answer to add on the initial amount.

[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{25\times 55}{100} =25\times55=1375\div100=13.75[/tex]
[tex]=13.75[/tex]

Now add:
[tex]55+13.75=68.75[/tex]
[tex]=68.75[/tex]

After a 25% increase on an item that costs 55 dollars, the new sale price will cost "$68.75 cents."

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)

It can be deduced that the null hypothesis is H: p = 0.25 and the alternative hypothesis is H: p > 0.25.

It should be noted that null and alternate hypothesis are written based on the population parameter.

From the information given, the claim is that they card was identified significantly more than chance would suggest. The proportion of card selected will be:

= 1/4 = 0.25

Therefore, the null hypothesis is H: p = 0.25 and the alternative hypothesis is H : p > 0.25.

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:

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

Answer:

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

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.

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]

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.

The area of the compound figure = Area of triangle A + Area of triangle B + Area of rectangle C + Area of triangle D

[tex]\text{The area of the compound figure} = (0.5 \times 7 \times10) + (0.5 \times 5 \times5) + ( 5\times 3 ) +(0.5\times5\times2)\\\\\text{The area of the compound figure} = 35 + 12.5 + 15 + 5\\\\\text{The area of the compound figure} = 67.5\rm\ units^2[/tex]

Answer:

Slope = m = 10/3 and y-intercept = (0, 16/3)

Step-by-step explanation:

-10x + 3y - 6 = 10

3y = 10x + 16

y = 10/3x + 16/3

Slope = m = 10/3

y-intercept = (0, 16/3)

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.
