Find the sixth term of a geometric sequence with which a, =-3 and r=-2.
Answer: 96
Step-by-step explanation: a is the initial term, and r is the ratio by which a increases. Multiplying -2 by -3 five times gives this sequence: -3, 6, -12, 24, -48, 96
Solve for x in the diagram * 10 POINTS HELP*
Answer:x+42+3x = 90
Combine like terms:
3x+x = 4x
42+4x = 90
Subtract 42 to both sides
90-42 = 48
Divide 4 by 48
48/4 = 12
X = 12

Use the vertical method to multiply (4a^3 - 2a + 3a^2 + 1) (4a3−2a+3a2+1) and (3 - 2a + a^2). (3−2a+a2). What would be the value of D?
Answer: C 3a^4
Step-by-step explanation:
I just took the test
The multiplication operation to multiply the equation (4a^3 - 2a + 3a^2 + 1) and (3 - 2a + a^2) with vertical method is done and the value of D obtained is 3a⁴.
What is vertical method to multiply?The vertical method to multiply is one of the simple method to perform multiplication operation.
In this method, the two terms which need to be multiply is kept one below the other and each element of first is multiplied with the other term.
The equations given in the problem are, (4a^3 - 2a + 3a^2 + 1) (4a3−2a+3a2+1) and (3 - 2a + a^2). (3−2a+a2). Arrange them and write in vertical manner to multiply.

What is Trigonometry?One of the six mathematical functions used to express the side ratios of right triangles, the trigonometric function includes the sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). The figure shows these six trigonometric functions in respect to a right triangle. Surveying, engineering, and navigation issues where one of a right triangle's acute angles and the length of a side are known but the lengths of the other sides need to be determined can be solved with ease using trigonometry.
As per the given data:
x = 41 cm
v = 17 cm
∠W = 134°
To find the length of w:
From the cosine law: [tex]cos(W) = \frac{x^2 + v^2 - w^2}{2xv}[/tex]
[tex]w = \sqrt{x^2 + v^2 - 2xvcos(W)}\\w = \sqrt{(41)^2 + (17)^2 - 2(41)(17)cos(W)}\\w = \sqrt{1681 + 289 + 968.35} = \sqrt{2938.35}\\w = 54 \:cm[/tex]
Hence, the length of w is 54 cm.

Solve the following quadratic equation
(x-18)^2=1.
A. x = 19 and x = 17
B. x = -19 and x = -17
C. x = -19 and x = 17
D. x = 19 and x = -17
To solve the quadratic equation (x - 18)^2 = 1, we can take the square root of both sides and consider the positive and negative roots. Here's how we can proceed:
Taking the square root of both sides gives us:
x - 18 = ±√1
Simplifying the square root of 1, we have:
x - 18 = ±1
Now, let's solve for x by considering both the positive and negative cases:
Case 1: x - 18 = 1
Adding 18 to both sides:
x = 1 + 18
x = 19
Case 2: x - 18 = -1
Adding 18 to both sides:
x = -1 + 18
x = 17
Leading to our final correct answer is:
A. x = 19 and x = 17

4x and 6x sit on a straight line therefore must equal to 180°
4x+6x = 180° (∠'s on str. line)
10x = 180
x= 180/10
x= 18
Then we need to find ∠UYV
∠UYV = 4x

Quadrilateral ABCD is inscribed in the circle. What is the measure of angle C?
Answer: 92
Step-by-step explanation: Angles in an inscribed quad are supplementary and add to 360.
First solve for x:
2x+34=180
x = 73
Then, solve for c
3x + 49 + c = 360
3(73) + 49 + c = 360
268 + c = 360
c = 92
