Width = 23cm, length = 9cm

A rectangle's Area = Length * width

Area = 9 cm * 23 cm = 207 cm²

Area = 207 cm²

$width =23 cm\\ length = 9cm \\ \\ \boxed{Area= w \cdot l} \\ \\ Area=23 \cdot 9 \\ \\ Area=207 \ cm^2$

Find the slope x intercept and y intercept of the line y equals 2x + 1

Ad libitum [116K]

(i) Slope is $m=2$

(ii) x - intercept is $\left(-\frac{1}{2}, 0\right)$

(ii) y - intercept is $(0,1)$

Explanation:

The given equation is $y=2x+1$

We need to determine the slope, x - intercept and the y - intercept

(i) Let us determine the slope of the equation.

Since, the equation is of the form $y=mx+b$ where m is the slope

Thus, comparing the equation $y=2x+1$ with the general form $y=mx+b$ , the slope is 2.

Thus, slope is $m=2$

(ii) Now, we shall determine the x - intercepts.

The x - intercept can be determined by substituting $y=0$ in $y=2x+1$

Thus, we have,

$0=2x+1$

$-1=2x$

$\frac{-1}{2} =x$

Thus, the x - intercept is $\left(-\frac{1}{2}, 0\right)$

(iii) The y - intercept can be determined by substituting $x=0$ in $y=2x+1$

Thus, we get,

$y=2(0)+1$

$y=0+1$

$y=1$

Thus, the y - intercept is $(0,1)$

The growth rate of nominal gdp between 1998 9063 <br> and 2018 20501 was

Alex73 [517]

Answer:

The nominal GDP growth rate between 1998 and 2018 was 126.20 percent.

Step-by-step explanation:

Given that in 1998 the country's GDP was $ 9,063 and in 2018 it was $ 20,501, to determine the nominal growth rate of the nation's GDP, the following calculation must be made:

9,063 = 100

20,501 = X

((20,501 x 100) / 9,063) = X

2,050,100 / 9,063 = X

226.20 = X

226.20 - 100 = 126.20

Therefore, the nominal GDP growth rate between 1998 and 2018 was 126.20 percent.
