Answer: 1.64 2.100

Step-by-step explanation:

The reason for this is squaring something is simply mulyiplying the number by itself. for example

8 squared

there is a 2 above the 8 which means we will do 8x8.

8x8= 64

Hope this helps!!!!

given the arithemtic or geometric sequence, identify f(0) and the common difference ratio f(x) = 4-2/3x

ankoles [38]

Answer:

Required value of f(0) = 4 and common difference of given sequence is $\frac{-2}{3}$

Solution:

Given sequence rule for arithmetic sequence is $\mathrm{f}(\mathrm{x})=4-\left(\frac{2}{3}\right) x$

We need to determine f(0) and common difference

Calculating f(0).

Substituting x = 0 in given sequence rule we get

$\begin{array}{l}{f(0)=4-\left(\frac{2}{3}\right) 0} \\ {=4-0=4}\end{array}$

Calculating common difference

Let’s first calculate f(1) and f(2).

Substituting x = 1 in given sequence rule

$\begin{array}{l}{\mathrm{f}(1)=4-\left(\frac{2}{3}\right) 1} \\ {=4-\left(\frac{2}{3}\right)=\frac{10}{3}}\end{array}$

$\mathrm{f}(2)=4-\left(\frac{2}{3}\right) 2=4-\left(\frac{4}{3}\right)=\frac{8}{3}$

Common Difference can be found by subtracting f(1) from f(2)

$\text { Common difference }=\mathrm{f}(2)-\mathrm{f}(1)=\left(\frac{8}{3}\right)-\left(\frac{10}{3}\right)=\frac{-2}{3}$

Hence required value of f(0) = 4 and common difference of given sequence is $\frac{-2}{3}$

X-3 / 4 = r/4 pls show the steps and the answer for this problem

Dima020 [189]

$\\ \rm\longmapsto \dfrac{x-3}{4}=\dfrac{x}{2}$

$\\ \rm\longmapsto 2(x-3)=4x$

$\\ \rm\longmapsto x-3=\dfrac{4x}{2}$

$\\ \rm\longmapsto x-3=2x$

$\\ \rm\longmapsto x-2x=3$

$\\ \rm\longmapsto -x=3$

$\\ \sf\longmapsto x=-3$

Value of x in the given figure

ololo11 [35]

Answer:

$\sf\longmapsto \: x = 3$

Step-by-step explanation:

$\sf\longmapsto \: 6x - 7 = 4x - 1$

$\sf\longmapsto \: 6x - 4x = - 1 + 7$

$\sf\longmapsto \: 2x = 6$

$\sf\longmapsto \: x = 6 \div 2$

$\sf\longmapsto \: x = 3$

the number of cakes baked varies directly with the number of hours the caterers work. What is the ratio of cakes baked to hours

aniked [119]

The required ratio of cakes baked to hours worked = 30: 1

Concept:

We know that a ratio is a term in mathematics that signifies how many times one value contains the other.

Given: The number of cakes baked varies directly with the number of hours the caterers work.

Explanation:

From the given graph, it can observe that,

30 cakes are made in 1 hour. ( When we draw a vertical line from x = 1 to the curve, we get y=30 i.e. point is ( 1,30).

The required ratio of cakes baked to hours worked = 30: 1
