Can someone help pls? :)

Given:

In a set of 3 numbers the first is a positive integer, the second is 3 more than the first and the 3rd is a square of the second.

To find:

The equation for the given situation if the sum of the numbers is 77.

Solution:

a. Let the first number in the set is x.

The second is 3 more than the first. So, the second number is [tex](x+3)[/tex].

The 3rd number is a square of the second. So, the third number is [tex](x+3)^2[/tex].

Therefore, the first, second and third numbers are [tex]x,(x+3),(x+3)^2[/tex] respectively.

b. The sum of the numbers is 77.

First number + Second number + Third number = 77

c. So, the equation in terms of x is:

[tex]x+(x+3)+(x+3)^2=77[/tex]

Therefore, the required equation is [tex]x+(x+3)+(x+3)^2=77[/tex].

d. On simplification, we get

[tex]x+x+3+x^2+6x+9=77[/tex]                   [tex][\because (a+b)^2=a^2+2ab+b^2][/tex]

[tex]x^2+(6x+x+x)+(3+9)=77[/tex]

[tex]x^2+8x+12=77[/tex]

Subtract 77 from both sides.

[tex]x^2+8x+12-77=77-77[/tex]

[tex]x^2+8x-65=0[/tex]

Therefore, the simplified form of the required equation is [tex]x^2+8x-65=0[/tex].

They gave you the length of the two sides of the triangular part. Calculate the circumference of the semi circle on top.

Circumference of a semi circle is 1/2 x 2 x radius x PI

The radius is given as 3 ft.

Circumference  = 1/2 x 2 x 3 x 3.14 = 9.42ft

Perimeter is the length of the circumference of the semi circle plus the side lengths of the triangle:

5 + 5 + 9.42 = 19.42 feet

Answer:

76

Step-by-step explanation:

Since this is a right triangle, we  can use  trig functions

tan ? = opp side/ adj side

tan ? = 40 / 10

tan ?  = 4

Taking the inverse  of each side

tan ^ -1 (tan ?) = tan ^-1(4)

? =75.96375653

To the nearest degree

? = 76

Answer:

h=-2

k=-3

Step-by-step explanation:

in ax²+bx+c=0

sum of roots=-b/a

product of roots=c/a

sum of roots=5+h+1=h+6

product of roots=5(h+1)

so h+6=-(k-1)/1

so h+6=-k+1

h+k=1-6

h+k=-5

and 5(h+1)=-5/1

5(h+1)=-5

h+1=-5/5=-1

h=-1-1=-2

-2+k=-5

k=-5+2=-3

Answer: S=100.

Step-by-step explanation:

Since 8 is 8% of 100 we know this is right.

Answer:

S = 100

Step-by-step explanation:

The equation is 8/? = 8/100

Multiply 8 x 100 to get 800, then divide by 8% to get 100.

Answer:

Relative to such interrogate proposed, the answer is identified as 5520, if quantities ‘a’ and ‘b’ were to subject to define, given such conditions.

Step-by-step explanation:

Understood:

- Such quantity is a four (4) digit number, as explicitly stated.

- The value must be divisible by three (3). Thus, once the digits are summed, such quantity must be able to divide, and distribute evenly, into three (3).

- Likewise, such number is obligated to be divisible by five (5). Thus, the last digit of such quantity must end in either a ‘5’ or a ‘0’.

We were given the mathematical expression: 5a2b

5 + 2 = 7 + x = a number that is divisible by three, as stated in the problem.

X could be a list of differentiated number(s), although for a simplicity, x could be equated to as 5 to produce 12 (which is a factor of three, hence, divisible by three).

Now that ‘a’ has been substituted, ‘b’ must be substituted, similarly:

With ‘b’, we could appoint any number, so long that is either a 5 or 0 in the last digit, hence producing a value divisible my five.

For simplicity, which choosing either 5 or 0 does not make a difference, I will choose zero.

Thus, the rectified answer to such an interrogate is 5520. The difference between the largest of such number and the smallest is their abilities to become divisible by a certain constant ‘a’ and ‘b’.

Answer:

B

Step-by-step explanation:

B. Sine is an odd function because it is symmetric about the origin (along y=x or y=-x)

Answer: 3

Step-by-step explanation: I don’t have an explanation but I got the same question on a quiz and 3 was the correct answer.

the possible values for y are in between 20 and 80 will be 3.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

If 12 is the greatest common factor of y and 36.

The value of y will be a multiple of 12 and greater than 36.

Then the numbers will be

12 x 4 = 48

12 x 5 = 60

12 x 6 = 72

Then the possible values for y are in between 20 and 80 will be 3.

Answer:

$95.52

Step-by-step explanation:

Number of robots = 3

Cost of each robots = $398

Tax rate = 8%

Amount of tax of each robots = 8% of $398

= 8/100 × $398

= 0.08 × $398

= $31.84

TOTAL TAX to be paid = Amount of tax of each robots × Number of robots

= $31.84 × 3

= $95.52

TOTAL TAX to be paid = $95.52

The missing side is 53.6 units for the given right triangle.

A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.

The right triangle is given in the question, as shown.

The ratio of the length of the side opposite the angle to the length of the hypotenuse of the triangle. The sine function is denoted by the symbol "sin" and is defined as follows:

sin(θ) = opposite / hypotenuse

Here, θ = 66°

Using the sine ratio in the given triangle, we get

sin 66° = perdenicular/hypertanuas

Substitute the known values in the above ratio,

sin 66° = 49/x

x = 49/sin 66°

x = 53.63717

Rounded to the nearest tenth,

x ≈ 53.6

Thus, the missing side is 53.6 units for the given right triangle.
