What is the following product? (5 square root 2-4 square root 3) (5 square root 2-4 square root 3)

Zina [86]

Answer:

(5 square root 2-4 square root 3) (5 square root 2-4 square root 3)

= 98 - 40 $\sqrt{6}$

Step-by-step explanation:

i) (5 $\sqrt{2}$ - 4 $\sqrt{3}$ ) × (5√2 - 4√3)

=(5 $\sqrt{2}$ × 5 $\sqrt{2}$ ) - (5 $\sqrt{2}$ × 4 $\sqrt{3}$ ) - (4 $\sqrt{3}$ × 5 $\sqrt{2}$ ) + (4 $\sqrt{3}$ × 4 $\sqrt{3}$ )

= 50 - 20 $\sqrt{6}$ - 20 $\sqrt{6}$ + 48

= 98 - 40 $\sqrt{6}$

What is the length of AC? What is the measure of angle A? What is the measure of angle B?

kipiarov [429]

Answer/Step-by-step explanation:

✔️Find AC using Pythagorean Theorem:

AC² = 25.2² - 11.3²

AC² = 507.35

AC = √507.35

AC = 22.5 (nearest tenth)

✔️Find m<A using trigonometric ratio:

Reference angle = A

Opp = 11.3

Hyp = 25.2

Sin(A) = opp/hyp

Sin(A) = 11.3/25.2

A = sin^{-1}(11.3/25.2)

A = 26.6° (nearest tenth)

✔️Find m<B using trigonometric ratio:

Reference angle = B

Adj = 11.3

Hyp = 25.2

Cos(A) = adj/hyp

Cos(A) = 11.3/25.2

A = cos^{-1}(11.3/25.2)

A = 63.4° (nearest tenth)

2 2/3 + 12 6/8 how do I work this

barxatty [35]

Answer:

$\large\boxed{2\dfrac{2}{3}+12\dfrac{6}{8}=15\dfrac{5}{12}}$

Step-by-step explanation:

$2\dfrac{2}{3}+12\dfrac{6}{8}=2\dfrac{2}{3}+12\dfrac{6:2}{8:2}=2\dfrac{2}{3}+12\dfrac{3}{4}\\\\\text{Find}\ LCD:\\\\\text{List of multiples of 3:}\ 0,\ 3,\ 6,\ 9,\ \boxed{12},\ 15,\ ...\\\text{List of multiples of 4:}\ 0,\ 4,\ 8,\ \boxed{12},\ 16,\ ...\\\\12=3\cdot4\\\\\text{therefore}\\\\\dfrac{2}{3}=\dfrac{2\cdot4}{3\cdot4}=\dfrac{8}{12}\\\\\dfrac{3}{4}=\dfrac{3\cdot3}{4\cdot3}=\dfrac{9}{12}\\\\2\dfrac{2}{3}+12\dfrac{3}{4}=2\dfrac{8}{12}+12\dfrac{9}{12}=(2+12)+\dfrac{8+9}{12}=14+\dfrac{17}{12}\\\\=14+1\dfrac{5}{12}=15\dfrac{5}{12}$
