Answer:

$3.015*10^{-7}$ .

Step-by-step explanation:

Given : 0.0000003105 .

To find : Write in scientific notation.

Solution : We have given 0.0000003105.

Steps to write in scientific notation :

Step 1 : If a number has n digit we move decimal point ( n-1) place to left

and to balance , multiply by $10^{n-1}$ .

We can write 0.0000003105 as $\frac{3105}{10000000000}$ .

Or $\frac{3105}{10^{10}}$ .

$\frac{3.015*10^{3}}{10^{10} }$ .

$\frac{3.015}{10^{7} }$ .

$3.015*10^{-7}$ .

Therefore, $3.015*10^{-7}$ .

3.105 x 10 ^-6 because you are moving the decimal point back the exponent becomes negative

Rewrite y=5(14)t/6 in the form y=a(1+r)t or y=a(1−r)t. Round the value of r to the nearest ten thousandth. Then tell whether the

Sveta_85 [38]

Answer:

$y=5(1+0.5525)^t$ where r=0.5525 which is in the form of $y=a(1+r)^t$ or $y=a(1-r)^t$ ..

The expression represents an exponential growth function.

Step-by-step explanation:

Given that $y=5(14)^{\frac{t}{6}$

To rewrite the given equation in the form $y=a(1+r)^t$ or $y=a(1-r)^t$ ..

$y=5(14)^{\frac{t}{6}$

$=5((14)^{\frac{1}{6}})^t$

$=5[1.5525]^t$

$y=5(1+0.5525)^t$ where r=0.5525 which is in the form of $y=a(1+r)^t$ or $y=a(1-r)^t$ ..

Since 1.5525 > 1, we have that the expression represents an exponential growth function.

Find the missing dimension:if the perimeter is 6yards and the length is 6ft .what is the width?in yards

larisa [96]

Since you haven't identified this figure, I'm going to assume that it's a rectangle.

The Perimeter of a rectangle of length L and width W is P = 2L + 2W.

Here you are given the Perimeter and the length, and are to find the width, W.

Solving the above equation for W, we get P - 2L = 2W.
Dividing by 2 (to isolate that W), we get

P
-- - L = W
2

Substitute P= 6 yds and L = 6 feet (or 2 yds), find W (in yards).

Can u answer this please

Svetradugi [14.3K]

Answer:

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x - 4)² + (y - 3)² = 16 ← is in standard form → C

Given a sequence is defined by a first term of LaTeX: t_1=3t 1 = 3, and explicit definition LaTeX: t_n=\:4n-1t n = 4 n − 1, find

Debora [2.8K]

Answer:

$1) 15\: 2)(-4,-1,11,20,...)$

Step-by-step explanation:

1) To find the 4th term given the Explicit Formula, i.e. definition, just plug it in. The common difference according to question is 4, the 1st term is 3.

$t_{1}=3\\t_{n}=t_{1}+4(n-1)\\t_{n}=t_{1}+(n-1)d\\t_{4}=3+4(3)\\t_{4}=15$

2) For this another Sequence in Explicit definition we just need to plug it in:

$a_{n}=n^{2}-5\\a_{1}=1^{2}-5 \Rightarrow a_{1}=-4\\a_{2}=2^{2}-5\Rightarrow a_{2}=-1\\a_{3}=3^{2}-5\Rightarrow a_{3}=4\\a_{4}=4^{2}-5\Rightarrow a_{4}=11\\a_{5}=5^{2}-5\Rightarrow a_{5}=20\\(-4,-1,11,20,...)$
