Answer:
y = 0.2(0.5)^x
Step-by-step explanation:
Exponential function are of the form
y = ab^x
----------------------
To find "a" plug in x = 0 y = 0.2
0.2 = a(0.2)^0
0.2 = a
-------------------------
To find "b" plug in another point and a = 0.2
using x = 2, b = 0.05
0.05 = 0.2b^2
Divide both sides by 0.20
.25 = b^2
Take the square root of both sides
0.5 = b
-----------------------------
With a = 0.2 and b = 0.5 the equation becomes
y = 0.2(0.5)^x
Answer:
C
Step-by-step explanation:
(6 * 4 ) * 2 = 48
( 4 * 12 ) * 2 = 96
( 6 * 12 ) * 2 = 144
48 + 96 + 144 = 288
Thw measurements based on the arrow on the rulers will be:
A= 1.3cm
B = 2.1 cm
C = 3.4cm
D = 4.4cm
E = 5.5cm
F = 7cm
G = 8.2cm
H = 10.3cm
I = 11cm
J = 11.7cm
K = 12.7cm
L = 14.7cm
<h3>How to depict the measurement? </h3>
It should be noted that 10 millimeters make 1 cm. Therefore, to convert the centimeters to millimeters, you simply have to multiply by 10.
A = 1.3cm × 10 = 13mm
B = 2.1cm = 21mm
C = 3.4 × 10 = 34m
Using same method, the value of the remaining will be:
D = 44mm
E = 55mm
F = 70mm
G = 82mm
H = 103mm
I = 110mm
J = 117mm
K = 127mm
L = 147mm

Answer:
3
Step-by-step explanation:
3/4 (5x -3)+8=17
3/4 (5x -3) = 17 - 8 = 9
(5x -3) = 9 * (4/3)= 36/3 = 12
5x = 12 + 3 = 15
x = 3
