Answer:

x=2.2

Step-by-step explanation:

You know that for triangle ABC, side AB=10, CB=2 and AD=AB+BD=10+1=11. Given that triangles ABC and AED have the same angles, they are similar triangles.

So we can use the following ratios to solve for ED=x:

Let f be the function given by f(x)=5cos2(x2)+ln(x+1)−3. The derivative of f is given by f′(x)=−5cos(x2)sin(x2)+1x+1. What value
lesya [120]

Answer:

The value of c that satisfies the conclusion of the Mean Value Theorem applied to f on the interval [1,4] is approximately 0.1793.

Step-by-step explanation:

Given f(x) = 5cos²x² + ln(x + 1) - 3

The Mean Value Theorem applied to f on an interval [a, b] is given as

f'(x) = c = [f(b) - f(a)]/(b - a)

= [f(4) - f(1)]/(4 - 1)

c = [f(4) - f(1)]/3

f(4) = 5(cos4²)² + ln(5) - 3

= 3.2296

f(1) = 5(cos1²)² + ln(2) - 3

= 2.6916.

c = (3.2296 - 2.6916)/3

= 0.538/3

≈ 0.1793

Help help im so confused as per usual
Alik [6]

Answer:

Step-by-step explanation:

a. HM = 14

HN = 21

HK = 10.5

Based on intersecting chords theorem,

HK*HJ = HM*HN

10.5*HJ = 14*21 (Substitution)

HJ = 294/10.5

HJ = 28

b. VC = 7.2

VG = 12

Based on tangent-secant theorem, thus:

VD*VC = VG²

VD*7.2 = 12²

VD = 144/7.2

VD = 20

Therefore,

CD = VD - VC

CD = 20 - 7.2

CD = 12.8
