Answer:
24.05
Step-by-step explanation:
v² = u² + 2gs
(25)² =(12)² +2(10)s
625=144+20s
625-144=20s
481=20s
481/20=s
24.05=s
s=24.05

Step-by-step explanation:
if that is = a, find the value of a + 1 over a
[tex]3 - \sqrt{5} [/tex]
Answer:
7+√5/4
Step-by-step explanation:
if that is = a, find the value of a + 1 over a
Given that a = 3 - √5
a+1/1 = (3-√5)+1/3 - √5
4-√5/3 - √5
Rationalize
4-√5/3 - √5 * 3+√5/3 + √5
= 12 +4√5-3√5-√25/9-5
= 12+√5-5/4
= 7+√5/4
Hence the requred answer is 7+√5/4
Find the sum of the first eight terms of a geometric series is the fourth term of 25 in the constant ratio is 3/5 . Answer your answer as a decimal rounded to two places
25 = a1(1- (0.6)⁴)/(1-0.6)
25 = a1 (1- 0.13)/(0.4)
10 = a1(0.87)
a1 = 11.49
S8 = 11.49(1- (0.6)^8)/(1-0.6)
= 11.49(1-0.017)(1-0.6)
= 11.49(0.983)/0.4
= 28.24
The sum of the first eight terms of the given geometric series is; 28.24
How to find the sum of a geometric series?
We are told that the sum of the first four terms of the geometric series is 25. Thus, formula for sum of n terms of a geometric series is;
Sₙ = a(1 - rⁿ)/(1 - r)
where;
a is first term
r is common ratio
Thus;
25 = a(1 - (0.6)⁴)/(1 - 0.6)
25 = a(1 - 0.13)/(0.4)
10 = 0.87a
a = 11.49
Thus, sum of the first 8 terms of the series is;
S₈ = 11.49(1 - 0.6⁸)/(1 - 0.6)
S₈ = 11.49(1 - 0.017)(1 - 0.6)
S₈ = 28.24

If the area of a rectangle is expressed as x4 - 9y2, then the product of the length and the width of the rectangle could be expressed as 1) (x - 3)(x + 3y) 2) (r? – 3y)(x2 + 3y) 3) (r? – 3y)(r? - 3y) 4) (x +y)(x-9y)
Answer:
Step-by-step explanation:
the area of the rectangle is a difference of two squares
so it can be expressed
(x^2-3y)(x^2+3y)
Answer:
(x^2-3y)(x^2+3y) if you multiply them all together you get the final answer of x^4-9y^2

Answer:
[tex]x = 14[/tex]
Step-by-step explanation:

Step-by-step explanation:
Angles that will be congruent to the given angle, 94° would be any angle that is corresponding to 94°, any angle that is vertical to 94°, any angle that is the alternate interior angle to 94°.
Thus.
Angle 3 = 94° (vertical angles)
Angle 5 = 94° (corresponding angles)
Angle 6 = 94° (alternate interior angles)

Answer:
Step-by-step explanation:
simplify upper n lower fraction of LHS:
2^x+22^x+222^x
= 2^x*1 + (2*11)^x + (2*111)^x
= 2^x*1 + 2^x*11^x + 2^x*111^x
= 2^x*(1+11^x+111^x)
3^x+33^x+333^x
= 3^x*1 + (3*11)^x + (3*111)^x
= 3^x*1 + 3^x*11^x + 3^x*111^x
= 3^x*(1+11^x+111^x)
so LHS
= 2^x*(1+11^x+111^x) / (3^x*(1+11^x+111^x))
= 2^x / 3^x
= (2/3)^x
RHS = 9/4
= (3^2/ 2^2)
= (3/2)^2
= (2/3)^(-2)
so x = -2

Consider the graph of the function f(x)=e^x.
What is the range of function g if g(x)=f(x)+3?
Answer:
B. (3, ∞)
Step-by-step explanation:
Look at the graph of function f(x) = e^x.
The range is from 0, 0 not included, to infinity, or, in interval notation, (0, ∞).
The function g(x) = f(x) + 3 is the same as g(x) = e^x + 3.
g(x) is the the function f(x) shifted 3 units up.
That makes the range of g(x) from 3, 3 not included, to infinity.
Range: (3, ∞)

The mean of four numbers is 40. Three of the four numbers are 35, 41, and 41. What
is the fourth number?
Answer:
43
Step-by-step explanation:
Use the mean formula:
mean = (sum of elements) / (number of elements)
Let x represent the fourth number, and solve for x:
mean = (sum of elements) / (number of elements)
40 = (35 + 41 + 41 + x) / 4
40 = (117 + x) / 4
160 = 117 + x
43 = x
So, the fourth number is 43
