We need to know some log properties
1. when the base is not stated, assume that it is base 10 or log₁₀
2.
-log(10^-1)=
answer is D. -1
Answer:
The two given numbers are 10.5 units apart.
Step-by-step explanation:
Subtract the smaller from the larger. The larger number here is 6.2. Then we have
6.2 - (-4.3) = 6.2 + 4.3 = 10.5
The two given numbers are 10.5 units apart.
Answer:
Step-by-step explanation:
Angle ADC and angle CDJ are complementary. That means that they add up to equal 90 degrees. Therefore,
4x + 3x - 8 = 90 and
7x = 98 so
x = 14
Sub in a 14 for x in 3x - 8:
3(14) - 8 = 34
Angle CDJ = 34 degrees
Answer:
just use symbola
and place the two things you have
Step-by-step explanation:
i use it alot it helps you understand the y-intercept and x-intercept and ou can zoom in and zoom out also you can mark the ponts and change the line to make it a different color
Here,
let width(b)be x then,
length (l)=9cm+x
area =112 sq cm
now,
area of rectangle=l*b
or, 112=(9+x)x
or, 112=9x+x^2
or, 0=x^2+9x-112
or, 0=x^2+(16-7)x-112
or, 0=x^2+16x-7x-112
or, 0=x(x+16)-7(x+16)
or, 0=(x-7)(x+16)
either,
0=x-7
or,7=x
x=7cm
Or,
0=x+16
or, -16=x
x= -16[impossible,as distance is never negative] so,
x=7cm
therefore,length = 7cm + 9 cm = 16cm and width = 7cm.
