Answer:
+ 7 or - 7
Step-by-step explanation:
x^2 = 49
x = (49)^1/2 (1/2 means nothing but square root)
x = + or - 7
I said this answer because you square 7 and -7 and still get 49
1. Find the sum of the following AP:
2.7.12.....to 10 terms
06.17.28....to 100 terms
please answer
Answer:
245 and 55050
Step-by-step explanation:
The sum to n terms of an AP is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
In the first progression a₁ = 2 and d = 7 - 2 = 5, thus
[tex]S_{10}[/tex] = [tex]\frac{10}{2}[/tex] [ (2 × 2) + (9 × 5) ] = 5 × ( 4 + 45 ) = 5 × 49 = 245
-------------------------------------------------------------------------------
In the second progression a₁ = 6 and d = 17 - 6 = 11, thus
[tex]S_{100}[/tex] = [tex]\frac{100}{2}[/tex] [ (2 × 6) + (99 × 11) ]
= 50(12 + 1089) = 50 × 1101 = 55050
Which statement describes the effect on the parabola f(x) = 2x2 – 5x + 3 when it is changed to f (x) = 2x2 – 5x + 1?
A. The parabola is translated up 1 unit
B. The parabola is translated up 2 units.
O C. The parabola is translated down l unit.
OD. The parabola is translated down 2 units.
Answer:B
Step-by-step explanation:
The parabola f(x) = 2x² - 5x + 1 has been D. The parabola is translated down 2 units.
What is a quadratic equaton?A quadratic equation is an algebraic expression in the form of variables and constants.
A quadratic equation has two roots as it's degree is two.
We know the graph of a quadratic equation ax² + bx + c is a parabola that opens upwards and is symmetrical about the y-axis.
Given, a parabola f(x) = 2x² - 5x + 3.
Now it is changed to f(x) = 2x² - 5x + 1 which also can be written as,
f(x) = 2x² - 5x + 3 - 2, So it has been translated 2 units down along the y-axis.

please please help me with this, i’ll be waiting
Answer:
I think you have it
Step-by-step explanation:
It's not -4.44, and if it was -3.14 it would be closer to the -3 tick on the line. With the negative square root of 17 being 4.12 it's not that either. -11/3 is 3.6666667 or something along those lines so it would be closer to the -4 tick on the line, so I'm pretty sure you got it.
Two consecutive even integers add up to 1594. what are the two numbers?
Answer:
Hey there!
Consecutive integers mean that the numbers are next to each other.
Consecutive even integers mean that the numbers are separated by a number between them.
Thus, if x is the smaller number, x+2 can be used to write the larger number.
x+x+2=1594
2x+2=1594
2x=1592
x=796.
The two numbers are 796 and 798.

HELP!!
-5(4x-2) = -2(3+6x)
what is the answer and how do you get it
Answer:
x = 2
Step-by-step explanation:
-5(4x - 2) = -2(3 + 6x)
-20x + 10 = -6 - 12x Distribute -5 to 4x and -2 and distribute -2 to 3 and
6x
10 = -6 + 8x Add 20x to both sides
16 = 8x Add 6 to both sides
2 = x Divide 8 to both sides
Answer:
-0.5
Step-by-step explanation:
-5(4x-2) = -2(3+6x)
-20x-10 = -6-12x
-10 = -6+8x
-4 = 8x
-0.5 = x
- Maya is playing golf. On her first two holes,
she scored one under par then six over par.
Find her score after the first two holes.
Answer:
Her score after the first two holes is 5 over par
Step-by-step explanation:
Calculating golf scores we have;
Maya's score on the first hole is one under par
Maya's score on the second hole is six over par
Therefore we have Maya's score after the first two holes is given as follows;
She took one less than her allotted shot for the first score and 6 more than her allotted shot for the second hole
Her gross score is 1 under par + 6 over par = 5 over par
Therefore, her score after the first two holes is 5 over par
Answer:
5 holes over par
