Answer:
The sum of the first 6 terms of the inifinite series is -21.
Step-by-step explanation:
Following the sequence, we can see that each term is the previous term multiplied by -2. So, the first six terms are:
1, -2, 4, -8, 16, -32
The sum is:
1 - 2 + 4 - 8 + 16 - 32 = -1 - 4 - 16 = -21
The sum of the first 6 terms of the inifinite series is -21.
Answer:
-21
Step-by-step explanation:
Find the sum of the first 6 terms of the infinite series: 1 – 2 + 4 – 8 +

Find the zeros of the function and write in a+bi form.
-(x+1)^2-4=0
Answer:
x = -(1 + 4i)
or x = -1+4i
Step-by-step explanation:
From what we have;
-(x + 1)^2 = 4
(x + 1)^2 = -4
x + 1 = √-4
x + 1 = -4i or 4i
x = -1 - 4i or -1 + 4i
The ratio of money in Terry's bank account to Faye's bank account was 3:5.
Terry then put £220 in his account and Faye withdrew £300 from her account.
They now had the same amount in their accounts.
How much did Terry initially have?
Answer:
Terry's initial amount = £780
Step-by-step explanation:
Given that:
Ratio of Terry's money to Faye's money = 3 : 5
Let,
x be the amount of money.
Terry's amount = 3x
Faye's amount = 5x
Now,
3x + 220 = 5x - 300
220+300 = 5x - 3x
520 = 2x
2x = 520
Dividing both sides by 2
[tex]\frac{2x}{2}=\frac{520}{2}\\x=260[/tex]
Terry's initial amount = 3x = 3(260) = £780
Hence,
Terry's initial amount = £780

Complete the equation for the standard form of the line that has an x-intercept of -5 and a y-intercept of -4.
Answer:
Intercept form [tex]\frac{x}{-5} + \frac{y}{-4} = 1[/tex]
The standard form of the equation of the line
4 x + 5 y +20 =0
Step-by-step explanation:
Explanation
Given that x-intercept (a) = -5
and y-intercept (b) = -4
Intercept form
[tex]\frac{x}{a} + \frac{y}{b} = 1[/tex]
[tex]\frac{x}{-5} + \frac{y}{-4} = 1[/tex]
⇒ [tex]\frac{4x+5y}{-20} = 1[/tex]
4 x + 5 y = -20
Final answer:-
The standard form of the equation of the line
4 x + 5 y +20 =0

The length of a rectangle is 1 ft greater than its width. Each diagonal is 985 ft long. Find the dimensions of the rectangle.
length
ft:
width
ft:
Answer:
Width = 696.
Length = 697.
Step-by-step explanation:
Let the width be x, then the length = x+1 feet.
Using the Pythagoras Theorem:
x^2 + (x + 1)^2 = 985^2
x^2 + x^2 + 2x + 1 = 985^2
2x^2 + 2x - 970224 = 0
Using the quadratic formula:
x = [-2 +/- √(2^2 - 4*2*-970224)] / (2*2)
x = 696, -697(we ignore the negative root).
Graph the function. y = 1^x
Martin is buying a multi pack of 3 pairs of socks for $23.98. He will save $4.37 by buying the multipack instead of buying 3 individual pairs of the same socks. If each pair of socks costs the same amount, how much does each pair of socks cost when bought individually?
each pair of socks cost 10.79 when purchased individually
Step-by-step explanation:
25.98 + 6.39 = 32.37
32.37 ÷ 3 = 10.79

Help plz I don’t get this
Answer:
[tex]27x^2[/tex]
Step-by-step explanation:
1) First, "cancel out" the 3s. Remember, exponents are kind of like another way of saying, "multiply this number by itself this many times." Whatever the bigger number is is the number that you multiply by itself, and the smaller number at the top indicates how many times you have to do that.
Take [tex]3^4[/tex], for example. It's saying "multiply 3 by itself 4 times." Therefore, you can write it as (3)(3)(3)(3):
[tex]\frac{3^4x^4}{3x^2} \\= \frac{(3)(3)(3)(3)x^4}{(3)x^2} \\[/tex]
Now, simplify. For each 3 in the denominator, cross out a 3 in the numerator. So, cross out the single 3 in the denominator, and cross out one 3 in the numerator. Then, multiply the left over 3s. This gives us this:
[tex]\frac{(3)(3)(3)x^4}{x^2}[/tex]
[tex]= \frac{27x^4}{x^2} \\[/tex]
2) Do the same with the x's. Write them out, cancel them out, and then multiply the leftovers together:
[tex]\frac{27x^4}{x^2}\\= \frac{27(x)(x)(x)(x)}{(x)(x)}\\= 27 (x)(x)\\= 27x^2\\[/tex]
Therefore, [tex]27x^2[/tex] is the answer.

So whatever the input in x. Replace value of x in another side too.
Step-by-step explanation:
The question is not clear. Can you please attach the picture of the question?
Based on these observations, the following statements are true for the given function: f(0) = 3, f(1) = 4, and f(2) = 5.
What is Functions?Functions are mathematical entities that take an input, perform some operation on it, and produce an output.
They are often represented using function notation, such as f(x), where f is the name of the function and x is the input.
Using the given table and function f(x) = x + COF, we can make the following observations:
The value of COF is not provided in the table, so we cannot determine the exact equation of the function.From the table, we can see that f(0) = 3. This means that when x = 0, the value of the function is 3. We can substitute this value into the equation to find that 0 + COF = 3, which implies that COF = 3.With COF = 3, the equation for the function becomes f(x) = x + 3.From the table, we can see that f(1) = 4 and f(2) = 5, which are consistent with the equation f(x) = x + 3.The value of f(-1) is not provided in the table, so we cannot determine its value.The value of f(4) is not provided in the table, so we cannot determine its value.Thus, the statements that are true for the given function: f(0) = 3, f(1) = 4, and f(2) = 5.
