Answers

Answer 1

Answer:

B

Step-by-step explanation:

Here, we want to calculate the square root of -√- (75)

That will be

-√(25)(-3)

= -5 √(-3)

√(-3) is same as 3i

So we have the root as;

-5i√3

Step-by-step explanation:

1) the sum of 8 and t
3) the product of 5 and b

Answers

Step-by-step explanation:

When we say sum we are referring to addition.

And a number and a variable(letter) can't be added. So the sum of 8 and t can't be added.

The sum of 8 and t is;

8+t

When we talk about product or finding the product of a number we are referring to the number we get after multiplying two or more numbers.

And note that with multiplication, a number and a variable(letter) can be multiplied.

The product of 5 and b is;

5×b=5b

Write an expression to describe the sequence below. Use n to represent the position of a term in the sequence, where n = 1 for the first term. -91, -194, -291, -388

Answers

Answer:

[tex]T_n = -97n[/tex]

Step-by-step explanation:

The actual sequence is: -97, -194, -291, -388

Required

Determine the nth term

nth term of an arithmetic progression is:

[tex]T_n = T_1 + (n - 1)d[/tex]

Where

[tex]T_1 = First\ Term = -97[/tex]

[tex]d = Common\ Difference = -194 - (-97) =-97[/tex]

So:

[tex]T_n = T_1 + (n - 1)d[/tex] becomes

[tex]T_n = -97 + (n - 1) * -97[/tex]

[tex]T_n = -97 -97n + 97[/tex]

Collect Like Terms

[tex]T_n = -97n + 97-97[/tex]

[tex]T_n = -97n[/tex]

Hence, a term of the sequence is:

[tex]T_n = -97n[/tex]

Walkway Over the Hudson, a bridge that crosses the Hudson River in Poughkeepsie, is 2.063
kilometers long. Anping Bridge, which was built in China 850 years ago, is 2.07 kilometers long.
a. What is the total span of both bridges?
Show your thinking
b. How much longer is the Anping Bridge
than the Walkway Over the Hudson?

Answers

Answer: 4.126 km

Step-by-step explanation:

First, We have to find total span of both bridges

As Question indicates 'total' ,that is, we have to find bridge length in total ( You can join Bridges to have better understanding)

Now, Walkway over hundson Bridge length= 2.063 km

Amping bridge length= 2.07 km

So, Total span of both bridges = 2.063+2.07 = 4.133 km

b) Now Leah wanna walk across and back on walkway over hudson ,that is, she wanna return to starting point from where she walk forth

So,that means, she walk double distance of length of walkway over hudson

So, total distance = 2× 2.063

= 4.126 km

A central angle has a measure of 1 radian if:
A. the length of the arc it intercepts is twice the length of the radius.
B. the central angle is 90°.
C. the length of the arc it intercepts is the same as the length of the
radius.
O D. the radius has a length of 1

Answer:

C.) the length of the arc it intercepts is the same as the length of the radius

Step-by-step explanation:

The length of the arc it intercepts is the same as the length of the

radius option (C) is correct.

What is a circle?

It is defined as the combination of points that, and every point has an equal distance from a fixed point (called the center of a circle).

As we know, the relationship between arc length and the central angle:

s = rθ

[tex]\rm \theta = \dfrac{s}{r}[/tex]

Where 's' is the arc length and θ is the central angle, r is the radius of the circle.

If θ = 1 radian

Then,

s = r

Thus, the length of the arc it intercepts is the same as the length of the

radius option (C) is correct.

a = 51.4

Step-by-step explanation:

sinA = sinB

  a         b

sin(117) = sin(12)

   a             12

a * sin(12) = 12 * sin(117)

a = 12 * sin(117)

a = 51.4

Answer:

            C.    y + 7 = -7(x - 3)

Step-by-step explanation:

The equation of a line is:

                          y - y₀ = m(x - x₀)

where m is the slope and (x₀, y₀) is the point which the line passes through

The product of slopes of two perpendicular lines is  -1

so if given lines slope is ¹/₇ them:

     ¹/₇·m = -1

        m = -7

(3, -7)     ⇒    x₀ = 3,  y₀ = -7

Therefore:

               y - (-7) = -7(x - 3)

                y + 7 = -7(x - 3)

(if you don't want to do all of this you can use

Step-by-step explanation:

((3•5x2) +  7x) -  2

Factoring  15x2+7x-2

The first term is,  15x2  its coefficient is  15 .

The middle term is,  +7x  its coefficient is  7 .

The last term, "the constant", is  -2

Step-1 : Multiply the coefficient of the first term by the constant   15 • -2 = -30

Step-2 : Find two factors of  -30  whose sum equals the coefficient of the middle term, which is   7 .

     -30    +    1    =    -29

     -15    +    2    =    -13

     -10    +    3    =    -7

     -6    +    5    =    -1

     -5    +    6    =    1

     -3    +    10    =    7    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -3  and  10

                    15x2 - 3x + 10x - 2

Step-4 : Add up the first 2 terms, pulling out like factors :

                   3x • (5x-1)

             Add up the last 2 terms, pulling out common factors :

                   2 • (5x-1)

Step-5 : Add up the four terms of step 4 :

                   (3x+2)  •  (5x-1)

            Which is the desired factorization

(5x-1)(3x+2)

Write y – 3 = 23 (x – 2) in standard form. PLEASE HELP BEST ANSWER AND EXPLANATION WILL GET BRAINLIEST!!

Answers

Answer:

23x -y = 43

Step-by-step explanation:

in slope intercept form, we have y=mx+b where m=slope, b= y intercept

first let's simplify the expression 23(x-2)

y-3 = 23x - 23*2

y-3 = 23x - 46

now add 3 to both sides to move numbers to the right hand side

y -3 +3 = 23x -46 +3

y = 23x - 43

convert to standard form by having x and y on one side, numbers on the other.

add 43 to both sides

y+43 = 23x

subtract y from both sides

43 = 23x - y
