a circular fountain has a radius of 9.4 feet. find its diameter and circumference to the nearest tenth.

pickupchik [31]

Radius = r

Diameter : D = r*2

Circumference : C = 2πr

π = 3.14 rounded

9.4*2 =18.8

2(3.14)9.4

6.28*9.4= 59.03200

Diameter = 18.8

Circumference = 59.03200

Find a8 in the arithmetic sequence with a1=-7 and d=0.5

gavmur [86]

$\bf n^{th}\textit{ term of an arithmetic sequence}\\\\
a_n=a_1+(n-1)d\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
d=\textit{common difference}\\
----------\\
a_1=-7\\
d=0.5\\
n=8
\end{cases}
\\\\\\
a_8=a_1+(8-1)d\implies a_8=-7+(8-1)(0.5)$

and surely you know how much that is.

Find the x- and y-intercepts of the graph of the equation y = x2 – 2.

sertanlavr [38]

Answer:

See below ~

Step-by-step explanation:

X-intercept(s) : Take y = 0

0 = x² - 2
x = ±√2
X-intercepts are : (-√2, 0) and (√2, 0)

Y-intercept : Take x = 0

y = (0)² - 2
y = -2
Y-intercept is : (0, -2)
