Answer:

FV= $4,948.16

Step-by-step explanation:

Giving the following information:

Number of periods (n)= 10

Interest rate (i)= 2.15% compound interest annually

Present value (PV)= 4,000

<u>To calculate the future value, we need to use the following formula:</u>

FV= PV*(1+i)^n

FV= 4,000*(1.0215^10)

FV= $4,948.16

SOMEONN HELPPP MEEE PLEASEEE The measures of two complementary angles have a ratio of 2 : 7. What is the measure of the smaller
guapka [62]

When you say two angles are complementary, they add up to 90 degrees.

Since two angles are the ratio 2:7, you can represent the smaller angle as 2x and the larger as 7x.

add them up as 2x+7x=90

2x+7x=9x      90/9x=10x

the angles are 2x=20 degrees and 7x=70 degrees

so the smaller angle is 20 degrees

Determine the intercepts of the line.<br> - 4x + 7 = 2y - 3
Bingel [31]
-4x+7=2y-3
Put this in y=mx+b
-4x+10=2y
Switch it around
2y=10-4x
Put it in y=mx+b
2y=-4x+10
Divide by 2
y=-2x+5

The solution to 3x2 – 12x 24 = 0 is
zzz [600]
3x^2 - 12x + 24 = 0 \\ x^2 - 4x + 8 = 0 \\ x= \frac{-b \pm  \sqrt{ b^{2} -4ac} }{2a} &#10;; where a = 1, b = -4 and c = 8
x= \frac{-(-4) \pm \sqrt{ (-4)^{2} -4 \times 1 \times 8} }{2 \times 1} \\ = \frac{4 \pm \sqrt{ 16 -32} }{2} \\ =\frac{4 \pm \sqrt{ -16} }{2} \\ =\frac{4 \pm 4i }{2} \\ =2+2i \ or \ 2-2i

If 32 Superscript 2 c Baseline = 8 Superscript c + 7, what is the value of c? 1 2 3 5
eimsori [14]

Answer:

Option 3 - The value of c is 3.

Step-by-step explanation:

Given : If 32 Superscript 2 c Baseline = 8 Superscript c + 7.

To find : What is the value of c?

Solution :

Superscript denotes the power.

32 Superscript 2 c i.e. 32^{2c}

8 Superscript c + 7 i.e. 8^{c+7}

The equation form is 32^{2c}=8^{c+7}.

Write the expression as,

(2^5)^{2c}=(2^3)^{c+7}

(2)^{10c}=(2)^{3c+21}

Comparing the base,

10c=3c+21

10c-3c=21

7c=21

c=\frac{21}{7}

c=3

Therefore, the value of c is 3.

So option 3 is correct.
