The right answer is g(x)=(1/4x)^2 had the same question!!

Please write x^2, not x2.

If you stretch the graph of y=x^2 vertically by a factor of 4, the resulting graph represents the quadratic function y = 4x^2.  It's still a parabola, but appears to be thinner.

This particular question is about horizontal stretching, however.  Stretching the graph horizontally by a factor of 4 results in the new function g(x) = (x/4)^2.  Try graphing x^2 and also (x/4)^2 on the same set of axes to observe this phenomenon.

The sum of the first terms of an Arithmetic progression (Ap) is 130.if the fifth term is 3times,the first term,find the (a)commo
Nadusha1986 [10]

Answer:

For part a)

130 = 10/2[2a+(10-1)d]

Simplify, u get

2a + 9d = 26.................(1)

Also U5 = a + (5-1)d = 3a

Simplify, u get

a= 2d...................(2)

Substituting for a in equation 1,

2(2d)+9d= 26

Solving for d, we get

d = 2

In part b) substituting for d in equation 2 to get the first term

a = 2(2) = 4

Part c) the no. of terms required can be obtained by solving

28 = 4+(n-1)2

n = 13

What is the value of log 43? Use the calculator. Round your answer to the nearest tenth.
Bad White [126]

Answer:

The value of log  43is 1.633

Step-by-step explanation:

Explanation:

Suppose you know that:

\begin{array}{l}{\log 2 \approx 0.30103} \\{\log 3 \approx 0.47712}\end{array}

Then note that:

43=\frac{129}{3} \approx \frac{128}{3}=\frac{2^{7}}{3}

So

\log 43 \approx \log \left(\frac{2^{7}}{3}\right)=7 \log 2-\log 3 \approx 7 \cdot 0.30103-0.47712=1.63009

We know that the error is approximately:

\log \left(\frac{129}{128}\right)=\log 1.0078125=\frac{\ln 1.0078125}{\ln 10} \approx 0.00782 .3=0.0034

So we can confidently give the approximation:

\log 43 \approx 1.633

Sara has rs. 836 with her. she gives 9/11 of this to her sister. out of the remaining money, she gives rs. 38 to her brother. sh
Minchanka [31]

The original amount Sara has left is 172/209

The calculation can be done as follows

Let y represent the amount left

9/11 × 836

= 7524/11

= 110

Y  can be calculated as follows

Y + 38 +110= 836

148 + Y= 836

Y= 836 - 148

Y= 688

Therefore the fraction is

688/836

= 172/209

Hence the fraction of the original amount left is 172/209
