Answer:

sec(A) = -(1/5)√74

Step-by-step explanation:

Solving the equation for y, we have ...

-7x = 5y

-7/5x = y

The slope of this line (-7/5) is the tangent of the angle (A) it makes with the x-axis. The secant satisfies the relation ...

sec(A)^2 = 1 + tan(A)^2

sec(A) = √(1 +tan(A)^2)

sec(A) = -√(1 +(-7/5)^2) = -√(74/25) . . . . secant is negative in 2nd quadrant

sec(A) = -(1/5)√74

Can someone please help for 3/4

ivolga24 [154]

Answer:

3. 2kg/m 4. 1.524 meters

Step-by-step explanation:

3. 20g/cm to kg/m.

(20g÷1000g)kg ÷ (1cm÷100cm)m

1/50kg ÷ 1/100m

1/50 x 100/1=2kg/m

4. 1nch=2.54cm.

1foot=12inches

5feet= 5x12

=60inches

1inch=2.54cm

60nches=60×2.54

=152.4cm

100cm=1m

152.4cm=152.4÷100

=1.524m

thus 5 feet=1.524meers

A particle is moving horizontally along the x-axis. Its position (in ft) is: s(t)=t^3-18t^2+33t+14 where t is in sec.

UNO [17]

Answer:

t=11 sec

Step-by-step explanation:

The position of the particle moving along the x-axis is given by:

$s(t) = {t}^{3} - 18 {t}^{2} + 33t + 14$

The velocity is given by:

$s'(t) = 3 {t}^{2} - 36{t} + 33$

If s'(t)>0 then the particle is moving right.

$3 {t}^{2} - 36{t} + 33 \: > \: 0 \\ {t}^{2} - 12{t} + 11\: > \: 0$

$\implies \: t \: < \: 1 \: or \: t \: > \: 11$

This means that the particle is moving left when

$1 \: < \: t \: < \: 11$

The particle changes direction at time t=1 or t=11
