What is the product?

Sophie [7]

Answer:

Step-by-step explanation:

In exponent multiplication, if base are same just add the powers.

$(-6a^{3}b+2ab^{2})(5a^{2}-2ab^{2}-b)=(-6a^{3}b)*(5a^{2}-2ab^{2}-b)+2ab^{2}*(5a^{2}-2ab^{2}-b)\\\\$

$=(-6a^{3}b)*5a^{2}-(-6a^{3}b)*2ab^{2}-(-6a^{3}b)*b+ 2ab^{2}*5a^{2}-2ab^{2}*2ab^{2}-2ab^{2}*b\\\\=-30a^{3+2}b+12a^{3+1}b^{1+2}+6a^{3}b^{1+1}+10a^{1+2}b^{2}-4a^{1+1}b^{2+2}-2ab^{2+1}\\\\=-30a^{5}b+12a^{4}b^{3}+6a^{3}b^{2}+10a^{3}b^{2}-4a^{2}b^{4}-2ab^{3}\\$

Using trig how do you answer this

Aneli [31]

Answer:

62.73° or 1.09 radians

Step-by-step explanation:

SOH CAH TOA

sin = $\frac{opposite}{hypotenuse}$ , so sin (?) = $\frac{8}{9}$

this means that ? = $sin^{-1}(\frac{8}{9})$ or ? = arcsin( $\frac{8}{9}$ ), depending on what calculator you have

plugging in $sin^{-1}(\frac{8}{9})$ or arcsin( $\frac{8}{9}$ ) into calculator will get you

62.73° or 1.09 radians

use the corresponding answer depending on if the question asks for degrees or radians

Triangle FGH is similar to triangle IJK. Find the measure of side KI. Round your

erastovalidia [21]

Answer:

$5.8$

Step-by-step explanation:

Similar shapes also maintain a constant proportion of sides. Therefore, we can set up the following equation:

$\frac{31}{43}=\frac{\text{KI}}{8}$

Solving, we get:

$\text{KI}=\frac{8\cdot 31}{43}\approx \boxed{5.8}$
