What is the absolute value of 4+7i is equal to the square root of ______

Answer:

The absolute value of 4+7i is equal to \sqrt{4^{2}+7^{2}}.

The absolute value of the 4+7i be \sqrt{65}.

Step-by-step explanation:

The absolute value is given by .

|a + bi| = \sqrt{a^{2}+b^{2}}

Now find the absolute value of the 4+7i.

|4+ 7i|= \sqrt{4^{2}+7^{2}}

|4+ 7i| = \sqrt{16+49}      

|4+ 7i| = \sqrt{65}  

Therefore the absolute value of the 4+7i is \sqrt{65} .

Which expressions could complete this equation so that it has one solution? 4(4x-3)-6x= Choose exactly two answers that are correct. A. 12x-12-2x B. 9x-12 C. 4x+2(3x-6) D. 3x-3(2x-4)

A and C are correct! because....
4(4x-3)-6x = 16x-12-6x = 10x-12 

A. 12x-12-2x = 10x-12 So, A has a same equation with 4(4x-3)-6x
B. 9x-12 We can't do any thing with it. So, B is 9x-12 which is not the same equation with 4(4x-3)-6x
C. 4x+2(3x-6) = 4x+6x-12 = 10x-12 This one got the same equation too
D.3x-3(2x-4) = 3x-6x+12 = -9x+12 which is not the same equation with 4(4x-3)-6x

In ∆ABC shown below, ∡BAC is congruent to ∡BCA. Given: Base ∡BAC and ∡ACB are congruent. Prove: ∆ABC is an isosceles triangle. Construct a perpendicular bisector from point B to line segment AC. Label the point of intersection between this perpendicular bisector and line segment AC as point D. m∡BDA and m∡BDC is 90° by the definition of a perpendicular bisector. ∡BDA is congruent to ∡BDC by the definition of congruent angles. Line segment AD is congruent to line segment DC by _______1________. ∆BAD is congruent to ∆BCD by the _______2________. Line segment AB is congruent to line segment BC because corresponding parts of congruent triangles are congruent (CPCTC). Consequently, ∆ABC is isosceles by definition of an isosceles triangle. options are: a)1. Angle-Side-Angle (ASA) Postulate 2. corresponding parts of congruent triangles are congruent (CPCTC) b) 1. corresponding parts of congruent triangles are congruent (CPCTC) 2. Angle-Side-Angle (ASA) Postulate c) 1. the definition of a perpendicular bisector 2. Angle-Side-Angle (ASA) Postulate d) 1. corresponding parts of congruent triangles are congruent (CPCTC) 2. the definition of a perpendicular bisector

Refer to the image attached.

Given: \angle BAC and \angle BCA are congruent.

To Prove: \Delta ABC is an isosceles triangle.

Construction: Construct a perpendicular bisector from point B to line segment AC.  Label the point of intersection between this perpendicular bisector and line segment AC as point D.

Proof:

Consider \Delta BDA, \Delta BDC

\angle BDA = \angle BDC= 90^\circ

(By the definition of perpendicular bisector)

AD=DC (By the definition of perpendicular bisector)

So, Line segment AD is congruent to DC by the definition of perpendicular bisector.

\angle BAC = \angle BCA (given)

So,  \Delta BDA \cong \Delta BDC by ASA congruence postulate.

∆BAD is congruent to ∆BCD by the ASA congruence Postulate.

Line segment AB is congruent to line segment BC because corresponding parts of congruent triangles are congruent (CPCTC).

So, Option C is the correct answer.

Complete the factored form of the algebraic expression 18a + 3 = 3( _____+_____)

So to factorise an expression, you put it into a form where if you expanded the brackets, you'd get the given expression.. if that makes sense. Therefore, you need to multiply the 3 by something to get 18a, and so the first term is 6a. You don't need to multiply 3 by anything to get 3, so the second term is 1. The final result looks like:
3(6a + 1)

What method would you choose to solve the equation 2x2 – 7 = 9? Explain why you chose this method.

Since there is a power of 2 and constants, without a variable power of 1, I would use square root method.
Move the 7 to the right and you get 2x^2 = 16
Then divide both sides by 2 and get x^2 = 8
Now take the square root of each side and get x = +-sqrt 8
sqrt 8 can be simplified since 2*4 = 8 and 4 is a perfect square.
Therefore the final answer is x = +-2sqrt2

20(−1.5r+0.75) expand the expression and combine like terms

Answer:

-30r + 15

Step-by-step explanation:

We have been given that

20(−1.5r+0.75)

Use the distributive property a(b+c)=ab+ac.

20×(−1.5r)+20×0.75

Multiplying, we get

-30r +15

These two are not like terms. Hence , we cannot combine them.

Therefore, we cannot simplify it more.

Hence, the simplified expression is -30r + 15

In this triangle, the product of sin B and tan C is _____ , and the product of sin C and tan B is _______.

In this triangle, the product of sin B and tan C is c/a or cos B, and the product of sin C and tan B is b/a cos C. We determine these as follows:

sin B tan C = b/a (c/b) = c/a

sin C tan B = c/a (b/c) = b/a

Hope this answers the question. Have a nice day.
