Answer:

19(42 + 58)

Step-by-step explanation:

Assuming x = multiply, you are trying to solve the distributive property. Divide common factors from both terms (in this case 19).

Match each operation involving f(x) and g(x) to its answer.

galben [10]

F(x)=1-x² and g(x)=√(11-4x)

(g+f)(2)=>

1-(2)²+√(11-4(2))

=√3-3

(f/g)(-1)

(1-(-1)²)/(√(11-4(-1))

=0

(g-f)(-1)

√(11-4*-1)-(1-(-1)²

=√15

(g×f)(2)

1-(2)²×√(11-4(2))

-3√3

Suppose you deposit $12.50 into your savings account each week for 4 weeks and then withdraw $4.80 each week for the next two we

monitta

Answer:

The total change in the amount of money in my account is $ 9.60

Step-by-step explanation:

Given:

Amount of money deposited each week, $A_{d}=\$12.50$

Amount of money withdrawn each week, $A_{w}=\$4.80$

∴ Amount of money deposited in 4 weeks, $A_{dT}=A_{d}\times 4=12.50\times 4 = \$50$

∴ Amount of money withdrawn in 2 weeks, $A_{wT}=A_{w}\times 4=4.80\times 2 = \$9.6$

Now, amount of money left in the account is the difference of the two amounts.

So, amount left = $A_{dT}-A_{wT}=50-9.6=\$40.4$

Therefore, the total change in the amount of money in my account is given as:

Total change = Initial amount after 4 weeks - Final amount in the account.

Total change = $ 50 - $40.4 = $ 9.6

How is copying line segment similar to copying an angle?

makkiz [27]

Answer:

In terms of construction, copying a line segment and an angle requires a fixed compass width as a basic tool

Step-by-step explanation:

The basic similarity is in both constructions, or copies is that we are going to use the same compass width in each case as the basic tool to copy a line segment or an angle.
