Answer: C

Step-by-step explanation: The y-intercept is 1/5 since the point on the y-axis is (0, 1/5). The slope is 2/3 because the other coordinate is up 2 and right 3 from (0, 1/5) *remember rise over run*. The shading means that the answer (y) must be less than or equal to 2/3x + 1/5, hence it being underneath the line.

A regular hexagon is shown below. Find the value of X

Varvara68 [4.7K]

Answer:

$x=9$

Step-by-step explanation:

The expression is for the interior angle of the hexagon; one interior angle is equal to $(11x+21)^o$ .

Since an interior angle of a hexagon measures 120°, we have the equality

$(11x+21)=120$ .

Now it is just a matter of solving for $x:$

$11x=120-21\\\\11x=99\\\\x=\frac{99}{11} \\\\\boxed{x=9}$

A bank features a savings account that has an annual percentage rate of r=5.2% with interest compounded quarterly. Marcus deposi

Alexxx [7]

Answer:

(A) P = 8,500 , r = 0.052 , n = 4

(B) $12203.47

Step-by-step explanation:

* Lets explain how to solve the problem

- The annual percentage rate is R = 5.2%

- The interest is compounded quarterly

- Marcus deposits $8,500

- The account balance can be modeled by the exponential formula

S(t) = P(1 + r/n)^nt, where

# S is the future value

# P is the present value

# r is the annual percentage rate written as a decimal

# n is the number of times each year that the interest is compounded

# t is the time in years

* Lets solve the problem

∵ P is the present value

∵ Marcus deposits $8,500

∴ The present value is 8,500

∵ r is the annual percentage rate written as a decimal

∵ The annual percentage rate is 5.2%

∴ r = 5.2/100 = 0.052

∵ n is the number of times each year that the interest is compounded

∵ The interest is compounded quarterly

∴ n = 4

# (A)

* P = 8,500 , r = 0.052 , n = 4

# (B)

∵ S(t) = P(1 + r/n)^nt

∵ t is the time in years

∵ Marcus invests the money for 7 years

∴ t = 7

∴ S = 8500(1 + 0.052/4)^(4 × 7)

∴ S = 8500(1.013)^28 = 12203.47

* Marcus will have $12203.47 in 7 years

Find the slope of the graph of the linear equation.<br> y = -x - 2

Anastasy [175]

Answer:

slope is -1

Step-by-step explanation:

y=mx+b

(m=slope)

(b= y-intercept)

y-intercept= -2

slope and x is -x.

there is always a 1 in front of the x.

so...

-1x = mx take out x.

m= -1 or slope = -1

Find the Area of the figure below, composed of a parallelogram and one semicircle. Rounded to the nearest tenths place

frozen [14]

We have a parallelogram and a half of circle.

<h3> The area of parallelogram are: A=basis*height</h3><h3>The area of circle are: A=πr², where r is the radius (half of diameter). Thus the half circle have Area equals to:</h3>

$A=\frac{\pi r^{2} }{2}$

Approaching π to 3,14

parallelogram:

b=26

h=13

A=13*26

A=338

Half circle:

r=12

A=(3,14*12²)/2

A=226,08

<h2>Total Area of the figure are:</h2><h2>A=338+226,08</h2><h2>A=564,08</h2>
