What is equivalent to 4.321 × 10−4 ?<br><br> What is equivalent to 4.321 × 10−4 ?

Arlecino [84]

Please write that as 4.321 × 10^(−4). The " ^ " indicates exponentiation and the parentheses help make clear that your exponent here is a negative one.

Rewrite 4.321 × 10^(−4) by moving the decimal point 4 places to the left:

0.0004321

Find the slope of the tangent line to the graph of f at the given point.

jarptica [38.1K]

slope = 13

the slope of the tangent is f'( 4)

given f(x) = x² + 5x , then f'(x) = 2x + 5

and f'(4) = ( 2 × 4 ) + 5 = 13

3. How much interest does $5300 earn at a rate of 2.8% interest compounded quarterly after 6

azamat

Answer:

The interest is $I=\$74.46$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=6/12=0.5\ years\\ P=\$5,300\\ r=0.028\\n=4$

substitute in the formula above

$A=5,300(1+\frac{0.028{4})^{4*0.5}$

$A=5,300(1.007)^{2}$

$A=\$5,374.46$

<em>Find the interest</em>

$I=A-P$

substitute

$I=\$5,374.46-\$5,300=\$74.46$

Ou backpacked for a distance of 15.75 miles today. If you backpacked at an average speed of 1.26 miles per hour, how many hours

GarryVolchara [31]

12 $\frac{1}{2}$ hours

to calculate time divide distance by average speed

time = $\frac{15.75}{1.26}$ = 12.5 = 12 $\frac{1}{2}$
