Answer:

42.8

Step-by-step explanation:

42.763

You count back from the decimal point (the dot) by one and that is your one decimal place.

Numbers 5 - 9, when rounded up add one to the number above them and they and all numbers behind them turn into a zero. e.g 56 rounded to the nearest ten will give you 60

Numbers 0-4, when rounded up do not add one number above them but yet they and all numbers behind them still turn into zero. e.g 54 rounded to the nearest ten will give you 50.

So number 6 when rounded up adds one to 7. Then 6 and 3 turn into zero

Describe the transformations of the following function. y=tan(2x-π)

Romashka [77]

Answer:

To quickly solve this problem, we can use a graphing tool or a calculator to plot the equation.

Please see the attached image below, to find more information about the graph

The equation is:

y = tan(2x - π)

y = tan (2*(x-π/2))

We can compare it to its parent function

g(x) = tan(x)

The answer is

Option a.

Horizontal shrink by 1/2 and horizontal shift of π/2 to the right

This is Grade 9 Mathematics so I kinda stuck here so, if somebody can help me Please sin30⁰+csc60⁰

mamaluj [8]

$\huge\mathrm{Answer࿐}$

$\sin(30) + \csc(60)$

$\dfrac{1}{2} + \dfrac{2}{ \sqrt{3} }$

$\dfrac{ \sqrt{3 } + 4 }{2 \sqrt{3} }$

To remove √3 from denominator, we multiply both numerator as well as denominator with √3

$\dfrac{ \sqrt{3 } + 4 }{2 \sqrt{3} } \times \dfrac{ \sqrt{3} }{ \sqrt{3} }$

$\dfrac{3 + 4 \sqrt{3} }{6}$

A 6.50% coupon bond with 18 years left to maturity is offered for sale at $1,035.25. What yield to maturity [interest rate] is t

Basile [38]

Answer:

The yield to maturity is 6.3974%

Step-by-step explanation:

The computation of the yield to maturity is as follows

Given that

NPER = 18 × 2 = 36

PMT = $1,035.25 × 6.50% ÷ 2 = $33.65

PV = $1,035.25

FV = $1,000

The formula is shown below:

=RATE(NPER;PMT;-PV;FV;TYPE)

The present value comes in negative

AFter applying the above formula, the yield to maturity is

= 3.1987% × 2

= 6.3974%

Hence, the yield to maturity is 6.3974%

Which strategy best explains how to solve this problem?

Rufina [12.5K]

This is a geometric sequence because each term is twice the value of the previous term. So this is what would be called the common ratio, which in this case is 2. Any geometric sequence can be expressed as:

a(n)=ar^(n-1), a(n)=nth value, a=initial value, r=common ratio, n=term number

In this case we have r=2 and a=1 so

a(n)=2^(n-1) so on the sixth week he will run:

a(6)=2^5=32

He will run 32 blocks by the end of the sixth week.

Now if you wanted to know the total amount he runs in the six weeks, you need the sum of the terms and the sum of a geometric sequence is:

s(n)=a(1-r^n)/(1-r) where the variables have the same values so

s(n)=(1-2^n)/(1-2)

s(n)=2^n-1 so

s(6)=2^6-1

s(6)=64-1

s(6)=63 blocks

So he would run a total of 63 blocks in the six weeks.
