Answer:

2.3 units

Step-by-step explanation:

$\tan 25\degree =\frac{AC}{5}\\\\0.46630 = \frac{AC}{5}\\\\AC = 0.46630 \times 5\\AC =2.3315\\AC = 2.3 \: units$

Answer: 2.3

Step-by-step explanation:

We can use a trigonometric function to find AC

With respect to angle B (25º) BC is adjacent and AC is opposite.

The trigonometric function that relates adjacent and opposite is tangent.

$tan=\frac{opposite}{adjacent}$

Solve for opposite.

$opposite=tan*adjacent$

$o=tan(25)*5\\o=2.3$

Work out b(4½-3⅔)+1⅔

Zolol [24]

Answer:

2 $\frac{1}{2}$

Step-by-step explanation:

Change the mixed numbers to improper fractions

( $\frac{9}{2}$ - $\frac{11}{3}$ ) + $\frac{5}{3}$ ← the LCM of 2 and 3 is 6

= $\frac{9(3)}{2(3)}$ - $\frac{11(2)}{3(2)}$ + $\frac{5(2)}{3(2)}$

= $\frac{27}{6}$ - $\frac{22}{6}$ + $\frac{10}{6}$

= $\frac{5}{6}$ + $\frac{10}{6}$

= $\frac{15}{6}$

= $\frac{5}{2}$

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

How many digits are written when 1000 to the power of 2015 is expressed as a numeral?

PtichkaEL [24]

Answer: There are 6046 digits will be written on expansion upto 2015th power.

Step-by-step explanation:

Since we have given that

$1000^{2015}$

We have to find the number of digits ,

So,

$1000^{2015}\\\\=(10^3)^{2015}\\\\=10^{6045}$

Since we know that

$10^n\text{ has n+1 number of digits }$

so,

$10^{6045}\text{ has 6046 number of digits }$

Hence, there are 6046 digits will be written on expansion upto 2015th power.

This is from Khan academy I have to attach a PNG if you can help me solve it! Thank you!

Elenna [48]

Step-by-step explanation:

$\frac{5 {}^{ - 4x + 7} }{125 {}^{x} }$

$\frac{5 {}^{ - 4x + 7} }{5 {}^{3x} }$

$5 {}^{ - 4x + 7 - 3x}$

$5 {}^{ - 7x + 7}$
