Answer:

B. 16

Step-by-step explanation:

F(3) means we must plug the number "3" into the equation for each x.

Answer:

16

Step-by-step explanation:

F(x) = x² + 3x - 2

Let x=3

F(3)= 3^2 +3*3 -2

     = 9+9-2

    = 18-2

     =16

5. ALGEBRA Refer to the figure in
mamaluj [8]

The value of x that satisfies all the expressions of the system of linear equations is 20.

<h3 /><h3>Procedure - Determination of a variable associated to a pair of corresponding angles</h3>

According to the figure, angles 1 and 5 are <em>corresponding</em> angles between two <em>parallel</em> lines, therefore we have the following equivalence:

4\cdot x + 40 = 120 (1)

After some algebraic handling we find the value of x:

4\cdot x = 80

x = 20

The value of x that satisfies all the expressions of the system of linear equations is 20. \blacksquare

<h3>Remarks</h3>

There is a missing figure for the statement, we proceed to include it below after some research.

Pedro deposited $7,350 into a savings account 21 years ago. The account has an interest rate of 4.5% and the balance is currentl
Licemer1 [7]
The interest is compounded quarterly because the formula is
A=p (1+r/k)^kt
A it's 18810.67 but I will assume it's unknown ?
P present value 7350
R interest rate 0.045
K compounded quarterly 4
Now solve the formula as the interest is compoundedquarterly
A=7,350×(1+0.045÷4)^(4×21)
A=18,810.67

So the answer is quarterly

Two circles have radii of 4 units and 6 units. What is the radius of a circle whose area is equal to the sum of the areas of the
Bumek [7]

Answer:

Step-by-step explanation:

We that the area of a circle is Pi times r^2 where r is the radius

Let A be the area of the first circle and S the area of the second one and T the total one

A=4^2× Pi

S=6^2× Pi

T = Pi( 4^2 +6^2)

= Pi ( 16+36) = Pi× 52

52 is the radius square

So r = root square 52 = 2 root square 13

Help please
nika2105 [10]

Answer:

The correct option is Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16

Step-by-step explanation:

Consider the provided number line.

From the number line we can observed that:

1) A, B, C and D lies between -1 and 0.

2) Point A and B lies between -1 and -0.5

3) Point C and D lies between -0.5 and 0

Therefore, the value of A and B must have a negative value lying between -1 and -0.5

Also, the value of C and D must have a negative value lying between -0.5 and 0.

Now consider the provided options.

Option A) A=-5/16,B=-9/16,C=-0.7,D=-0.4

This is Incorrect representation because the value of C and D should lying between -0.5 and 0.

Option B) A=-0.4,B=-0.7,C=-5/16,D=9/16

This is Incorrect representation because the value of A and B should lying between -1 and -0.5.

Option C) A=9/16,B=-5/16,C=-0.4,D=-0.7

This is Incorrect representation because the value of C and D should lying between -0.5 and 0.

Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16

A = -0.7\\B = -\displaystyle\frac{9}{16} = -0.5625\\C = -0.4\\D = -\frac{5}{16} = -0.3125

Here the value of A and B lying between -1 and -0.5 also the value of C and D lying between -0.5 and 0.

Also they are in ascending order from -1 to 0.

Hence, the correct option is Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16
