Answer:

So for each point's numbers you have the x and the y. The first is the x, 2nd y in the parenthesis.

On the graph you start with the x axis, x in the middle is 0 to the left is the negative #'s and on the right: positive. Y axis is top positive, bottom negative! Now put the numbers on the axis' and then plot the points!

Hope this helps!!! :)

Suppose f is an exponential function and:

Nastasia [14]

Answer: a) $b= p(1 + r)^1$ b) $c= p(1 + r)^n$ c) $d= p(1 + r)^m$ d) $b^n=c$

Step-by-step explanation:

Since f is an exponential function.

So, it is expressed as

$f = p(1 + r)^$

Here f is the present value

p is the initial value

r is the rate of growth per time period

t is the time period.

(a) b represents the 1-unit growth factor for f.

$b= p(1 + r)^1$

(b) c represents the n n-unit growth factor for f.

$c= p(1 + r)^n$

$d= p(1 + r)^m$

Write a formula that expresses c in terms of b.

Since

$b=p(1+r)^1\\\\So,\\\\b=p(1+r)^{n\times \frac{1}{n}}\\\\b=(p(1+r)^n)^{\frac{1}{n}}\\\\b=c^{\frac{1}{n}}\\\\b^n=c$

Hence, a) $b= p(1 + r)^1$ b) $c= p(1 + r)^n$ c) $d= p(1 + r)^m$ d) $b^n=c$

Complete the square to make a perfect square trinomial. Then, write the result as a binomial squared. n^2-4n/3

ololo11 [35]

Answer:

(n- 2/3)²

Step-by-step explanation:

<em>Perfect square trinomial is: </em><em>a²+2ab+b²= (a+b)²</em>

We have:

n² - 4n/3

It can be put as:

n² -2×n×2/3

Here we consider n = a and -2/3 = b, then

b²= (-2/3)²= 4/9

Now we add 4/9 to a given binomial to make it perfect square:

n² - 2×n×3/2 + 4/9= (n- 2/3)²

So, added 4/9 and got a perfect square (n- 2/3)²

All the select drop box is. are not and are

Brilliant_brown [7]

Answer:

Step-by-step explanation:

Corresponding angles of both the squares are congruent. (angles of a square measure 90°)

Ratio of the sides of the given squares = $\frac{\text{Side length of small square}}{\text{Side length of the large square}}$

= $\frac{2}{5}$

This ratio of side lengths is constant for all corresponding sides.

Therefore, corresponding sides are proportional.

Since, all angles of both the squares are congruent and all the sides are proportional, both the squares will be similar.

Scale factor = $\frac{\text{Side length of large square}}{\text{Side length of the smaller square}}$

= $\frac{5}{2}$

= 2.5

This sequence of similarity transformations shows the figures are similar.

A high street store advertises 35% reduction on all clothing items. A dress costs £85 before the reduction. How much does it cos

Temka [501]

Answer:

£55.25

Step-by-step explanation:

Cost after reduction

=Cost before sale - Reduction in cost

= 85 - 35% of 85

= 85 - 0.35*85

= 85 - 29.75

= £55.25
