Answer:

= 18 $cm^{2}$

Step-by-step explanation:

As the triangle is right angled:

formula

= $\frac{1}{2}$ base x height

= $\frac{1}{2}$ 6 x 6

= $\frac{1}{2}$ x 36

= $\frac{36}{2}$

= 18 $cm^{2}$

Part C: YX = 24 meters and mYX = 120 degrees , then determine the radius of circle H.

astra-53 [7]

Answer: The radius is 11.5 meters (to the nearest tenth)

Step-by-step explanation: The circle with center H has an arc TX that measures 24 meters, and also the angle subtended by YX equals 120°.

The length of an arc is given b the formula;

Length of arc = (∅/360) x 2πr

Where the length of the arc is 24 and ∅ is 120, the formula becomes;

24 = (120/360) x 2(3.14) r

24 = (1/3) x 6.28 r

By cross multiplication we now have,

(24 x 3)/6.28 = r

72/6.28 = r

11.4649 = r

r ≈ 11.5

Therefore, the radius is approximately 11.5 meters

What is the value of 4a3 – 2b2 + 5 when a = 3 and b = −2? Which is equal to 33 • 35? A. 3^−2 B. 3^2 C. 3^8 D. 3^15

xz_007 [3.2K]

$1)4a^3-2b^2+5= 4* 3^3 - 2*(-2)^2+5= \\ \\ =4*27-2*4+5= \\ \\ =108-8+5= \\ \\ =100+5 \\ \\ =\boxed{105}$

2) 33*35=1155

A= 3⁻²= 1/3²= 1/9

B=3²=9

C=3⁸= 6561

D=3¹⁵= 14.348.907

$3)11^{24} \\ \\ 4) \frac{10^{12}}{10^{-3}}=10^{12}* 10^{3}=10^{15}$

550,000 x .205 = 112,750
550,000 + 112,750 = $662,750
To find the % of something, just move the decimal 2 places to the left to multiply.
