solve log4(x + 20) = 3
Answer:
Algebra Examples Rewrite log4(x+20)=3 log 4 ( x + 20 ) = 3 in exponential form using the definition of a logarithm. If x and b are positive real numbers and b ≠ 1 , then logb(x)=y log b ( x ) = y is equivalent to by=x b y = x .

An entry level civil engineer's annual pay is $63,648 based on 52 weeks per year. Due to the economy, his company is having to cut back on the number of weeks that it
employs its civil engineers. If the firm cuts the work year to 50 weeks but keeps the same rate of pay, how much should the civil engineer expect his annual pay to
decrease? Round your answer to the nearest dollar.
Answer:
$2448 in a year
Step-by-step explanation:
$63,648 ÷ 52 = $1224 a week (this would be how much he earns per week)
Since he is not getting paid for two week we do 52 - 2 = 50 week of work.
Since per week salary is $1224 we multiply by 2 for two weeks = $2448
Before $63,648 - $2448 = $61200 per year (Now he's making $61200/year)
Hope this helps,
if so please mark Brainlist,

Fine the equation of the line through (o, -3) perpendicular to y =4x+4
Answer:
The equation of the line is [tex]y = -\frac{x}{4} - 3[/tex]
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope and b is the y-intercept(the value of y when x = 0).
Perpendicular lines:
If two lines are perpendicular, the multiplication of their slopes is -1.
Line perpendicular to y = 4x + 4.
This line has slope 4, so our line will have slope:
[tex]4m = -1[/tex]
[tex]m = -\frac{1}{4}[/tex]
So
[tex]y = -\frac{x}{4} + b[/tex]
Through (0, -3)
This means that [tex]b = -3[/tex]
So
[tex]y = -\frac{x}{4} - 3[/tex]

sand is leaking through a small hole at the bottom of a conical funnel at the rate of 12cm3/s . if the radius of the funnel is 8 cm and the altitude of the funnel is 16 cm, find
a) the depth of the salt water after 30 second
b)the rate of change of its depth at that instant
Answer:
h ≅ 16.29 cm
[tex]\mathbf{\dfrac{dh}{dt}= -0.1809 \ cm/s}[/tex]
Step-by-step explanation:
From the conical funnel;
Let the adjacent line at the base of the cone be radius (r) and the opposite ( vertical length) be the height (h)
Then;
[tex]tan \theta= \dfrac{r}{h}[/tex]
[tex]tan \theta= \dfrac{8}{16}[/tex]
[tex]tan \theta= \dfrac{1}{2}[/tex]
∴
[tex]\dfrac{r}{h} = \dfrac{1}{2}[/tex]
[tex]r = \dfrac{h}{2}[/tex]
The volume (V) of the cone is expressed as:
[tex]V = \dfrac{1}{3}\pi r ^2 h[/tex]
[tex]V = \dfrac{1}{3}\pi (\dfrac{h}{2})^2 h[/tex]
[tex]V = \dfrac{\pi h^3}{3\times 4}[/tex]
[tex]\dfrac{dv}{dt} = \dfrac{3 \pi h^2}{3 \times 4} \dfrac{dh}{dt}[/tex]
[tex]\dfrac{dv}{dt} = \dfrac{ \pi h^2}{4} \dfrac{dh}{dt}[/tex]
Given that:
[tex]\dfrac{dv}{dt} = 12 \pi[/tex]
Then:
[tex]-12 \pi = \dfrac{ \pi h^2}{4} \dfrac{dh}{dt}[/tex]
[tex]- \int 48 \ dt = \int h^2 \ dh[/tex]
[tex]\dfrac{h^3}{3}= -48 t + c[/tex]
[tex]At \ t = 0 \ ; h = 0[/tex]
∴
[tex]\dfrac{0^3}{3} = -48(0) + c[/tex]
c = 0
So;
[tex]\dfrac{h^3}{3}= -48 t + 0[/tex]
[tex]\dfrac{h^3}{3}= -48 t[/tex]
t = 30
[tex]\implies h = (-48(30))^{1/3}[/tex]
h = 16.2865
h ≅ 16.29 cm
Thus;
from [tex]-12 \pi = \dfrac{ \pi h^2}{4} \dfrac{dh}{dt}[/tex]
[tex]\dfrac{-12 \pi} { \dfrac{ \pi h^2}{4} } =\dfrac{dh}{dt}[/tex]
[tex]\dfrac{dh}{dt} = \dfrac{-12 \pi} { \dfrac{ \pi h^2}{4} }[/tex]
[tex]\dfrac{dh}{dt}=\dfrac{-12 \times 4} { {16.29^2} }[/tex]
[tex]\mathbf{\dfrac{dh}{dt}= -0.1809 \ cm/s}[/tex]

A rectangular turf of size 20 feet by 30 feet is surrounded by a flower bed of uniform width
all around. The total area of the turf and the flower bed is 1200 sq.ft. What is the width of the
flower bed? Show your work algebraically.(4 points)
2) You are running a concession stand at a basketball game. You are selling hot dogs and
Answer:
5 ft
Step-by-step explanation:
Total area of turf and flower bed is [tex]1200\ \text{ft}^2[/tex]
Turf dimensions is 20 feet by 30 ft
Area of turf = [tex]20\times 30=600\ \text{ft}^2[/tex]
Area of flower bed = [tex]1200-600=600\ \text{ft}^2[/tex]
Let [tex]x[/tex] be the width of the flower bed so area of flower bed is
[tex]2\times 30x+2(20+2x)x=600\\\Rightarrow 30x+20x+2x^2=300\\\Rightarrow 2x^2+50x-300=0\\\Rightarrow x^2+25x-150=0\\\Rightarrow x=\dfrac{-25\pm \sqrt{25^2-4\times \:1\times \left(-150\right)}}{2\times \:1}\\\Rightarrow x=5,-30[/tex]
So, width of the flower bed is 5 ft.

HJ = 124
a. 15
b. 16
c. 9
d. 14
Answer:
A. 15
Step-by-step explanation:
The segment addition postulate states that the lengths of the pieces of a segment will add up to the length of the entire segment.
Using the segment addition postulate, The value of x is 15.
What is segment addition postulate?The segment addition postulate states that the lengths of the pieces of a segment will add up to the length of the entire segment.
WE have been given the following parameters;
HI = 6x + 8
DJ = 2x - 4
HJ = 124
Then by using the segment addition postulate,
HI + DJ + HJ
(6x + 8) +(2x - 4) = 124
8x + 4 = 124
8x = 120
x = 15
(6x + 8) = 6(15) + 8 = 78
(2x - 4) = 2(15) -4 = 20
Therefore, the value of x is 15.

A. 20.0
B. 21.2

Perimeter of ∆ABC = AB + BC + AC
A(-4, 1)
B(-2, 3)
C(3, -4)
✔️Distance between A(-4, 1) and B(-2, 3):
[tex] AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
