Answer:

7.23522974

Step-by-step explanation

7 would be in the ones place, 2 in the tenths, 3 in the hundredth, 5 in the thousandth, and so on. Since the number after 3 is over 5, it will go up by one. So the answer would be 7.23522974

Answer:

7.2352

Step-by-step explanation:

0.2 is the tenth place

0.03 is the hundredths place

0.005 is the thousandths place

0.0002 is the millionths place

7.2352297363 rounds down to 7.2352

This is true since 5 or higher would roundup, so 2 makes it round down.

which equation and ordered pair represent the correct vertex form and vertex for j(x) = x^2 - 12 x +7?

Aliun [14]

Answer:

see explanation

Step-by-step explanation:

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Given the equation in standard form : ax² + bx + c : a ≠ 0

then the x-coordinate of the vertex is

$x_{vertex}$ = - $\frac{b}{2a}$

j(x) = x² - 12x + 7 is in standard form

with a = 1, b = - 12 and c = 7, hence

$x_{vertex}$ = - $\frac{-12}{2}$ = 6

substitute x = 6 into j(x) for y- coordinate

y = 6² - 12(6) + 7 = 36 - 72 + 7 = - 29

vertex = (6, - 29 ) and

j(x) = (x - 6)² - 29 ← equation in vertex form

These dot plots show lengths (in feet) from a sample of crocodiles and alligators.

Alligators have a greater IQR because there were some very long alligators (high outliers)

One afternoon, Supreme sub shop sells 15 subs in 45 minutes. If the shop continues to sell subs at the same rate, about how many

melomori [17]

60 subs
Because it’s 15 per 45 and 45 times 4 is 180 which means that in 3 hours or 180 minutes they sold 15 times 4 amount of subs and 15 times four is 60. Hope this helps. Sorry if the explanation isn’t that good

Which number line shows the graph of -275/ -2 1 - 2 -- 2

Ray Of Light [21]

Answer: B

Step-by-step explanation: Since you know the number is not apart of the solution, the circle will definitely be open. But the circle is open so, it's apart of the problem

If equation of a circle is x^2 + y^2 + 6x + 4y + 10 = 1 What is this equation written in its standard form?

Darya [45]

$\text{The equation of a circle in standard form:}\\\\(x-h)^2+(y-k)^2=r^2\\\\(h,\ k)-center\\r-radius\\---------------------------\\\\Use\ (a+b)^2=a^2+2ab+b^2\\\\---------------------------$

$x^2+y^2+6x+4y+10=0\qquad\text{subtract 10 from both sides}\\\\x^2+6x+y^2+4y=-10\\\\x^2+2x\cdot3+y^2+2y\cdot2=-10\qquad\text{add}\ 3^2\ \text{and}\ 2^2\ \text{to both sides}\\\\(x^2+2x\cdot3+3^2)+(y^2+2y\cdot2+2^2)=-10+3^2+2^2\\\\(x+3)^2+(y+2)^2=-10+9+4\\\\\boxed{(x+3)^2+(y+2)^2=3}$
