Answer:  C) $1.05

Step-by-step explanation:

Given : All batteries were listed on sale for 15% off the regular price.

Discount price = 15%=0.15

Keith usually pays $6.99 for a battery for his watch.

Discount amount = \text{Price of a battery }\times\text{Discount percent}

=\$6.99\times0.15\\\\=\$1.0485\approx\$1.05\ \ \text{[ Rounded to the nearest cent.]}

Hence, discount will Keith receive on his purchase of a new watch battery = $1.05

Two vectors A⃗ and B⃗ are at right angles to each other. The magnitude of A⃗ is 5.00. What should be the length of B⃗ so that th
creativ13 [48]

Answer:

Length of B is 7.4833

Step-by-step explanation:

The vector sum of A and B vectors in 2D is

C=A+B=(a_1+b_1,a_2+b_2)

And its magnitude is:

C=\sqrt{(a_1+b_1)^2+(a_2+b_2)^2} =9

Where

a_1=Asinx

a_2=Acosx

b_1=Bsin(x+90)

b_2=Bcos(x+90)

Using the properties of the sum of two angles in the sin and cosine:

b_1=Bsin(x+90)=B(sinx*cos90+sin90*cosx)=Bcosx

b_2=Bcos(x+90)=B(cosx*cos90-sinx*sin90)=-Bsinx

Sustituying in the magnitud of the sum

C=\sqrt{(Asinx+Bcosx)^2+(Acosx-Bsinx)^2} =9

C=\sqrt{A^2sin^2x+2ABsinxcosx+B^2cos^2x+A^2cos^2x-2ABsinxcosx+B^2sin^2x} =9

C=\sqrt{A^2(sin^2x+cos^2x)+B^2(cos^2x+sin^2x)}

C=\sqrt{A^2+B^2} =9

Solving for B

A^2+B^2 =9^2

B^2 =9^2-A^2

Sustituying the value of the magnitud of A

B^2=81-5^2=81-25=56

B= 7. 4833

If f(x)= x2 + 5, and g(x) = 3x - 11, find (g(f(-3)).
fgiga [73]

Answer:

31

Step-by-step explanation:

first find f(-3)

f(-3) = (-3)^2 +5

       = 9+5 = 14

The find g(f(-3) = g(14)

                         = 3*14-11

                           = 42-11

                             =31
