Step-by-step explanation:
Yes it is .
7x+9 _> 7•3
7x+9_> 21
7x_> 21 - 9
7x _> 12 divide both side with 7 to find x
then x _> 1.4
which mean x can be any number that is greater than or equal to 1.4 so 2 is correct .
3:1/2 ×(11×4)
=1/2×44
=22m squared(2)
pretty sure double check with the example ur self okey so we make sure
in 1:i think it says to multiply lenght times width (L×W)
so its probably
area=l×w
=6 1/2 × 15 1/2
which when i put in the calculator it gives 45/2
H(x) = f(x)/g(x)
Use the quotient rule.
h '(x) = [g(x) f '(x) - f(x) g '(x)] / [g(x)]^2
=> h '(1) = [g(1) f '(1) - f(1) g '(1)] / [(g(1) ] ^2
h '(1) = [ 3*(-4) - 4*(-3)] / (3)^2 = [-12 + 12] / 9 = 0
Answer: 0
Answer:
2
Step-by-step explanation:
sin 90 is 1;
cos 360 is cos 0, or 1; and
tan 0 is 0.
Thus, sin 90° + cos 360° + tan 0° = 1 + 1 + 0 = 2

Step-by-step explanation:
<u>Step 1: Define</u>
We are given a right triangle. We can use trig to find the missing side length.
<u>Step 2: Identify Variables</u>
<em>POV from the angle measure</em>
Angle = 23°
Opposite Leg = 25
Adjacent Leg = <em>x</em>
<em />
<u>Step 3: Solve for </u><em><u>x</u></em>
- Substitution [tangent]: tan23° = 25/x
- Multiply <em>x</em> on both sides: xtan23° = 25
- Isolate <em>x</em>: x = 25/tan23°
- Evaluate: x = 58.8963
- Round: x ≈ 58.9
