Answer:
[tex]\large \boxed{ \sf y=-0.3\left|x-0\right|-7}[/tex]
Explanation:
Absolute value of a graph formula:
y = a |x -h| + kIdentify the vertex : (h, k) = (0, -7)
As the graph opens downward, take negative/fall coordinates.
Two points: (0, -7), (10, -10)
[tex]\sf Find \ slope \ (a) : \sf \ \dfrac{y_2 - y_1}{x_2- x_1} \ = \ \dfrac{-10-(-7)}{10-0} \ = -0.3[/tex]
Put them together: [tex]\bf y = -0.3|x - 0| -7 \ \ \ \approx \ \ y = -0.3|x| - 7[/tex]
Answer:
[tex]g(x)=-\dfrac{3}{10}|x|-7[/tex]
Step-by-step explanation:
Translations
For [tex]a > 0[/tex]
[tex]f(x)-a \implies f(x) \: \textsf{translated}\:a\:\textsf{units down}[/tex]
[tex]y=a\:f(x) \implies f(x) \: \textsf{stretched parallel to the y-axis by a factor of}\:a[/tex]
[tex]y=-f(x) \implies f(x) \: \textsf{reflected in the} \: x \textsf{-axis}[/tex]
-----------------------------------------------------------------------------------------
Parent function: [tex]f(x)=|x|[/tex]
From inspection of the graph, the transformed function has been reflected in the x-axis.
[tex]\implies -f(x)=-|x|[/tex]
The vertex of the parent function is the origin (0, 0). The vertex of the transformed function is at (0, -7). Therefore, there has been a translation of 7 units down.
[tex]\implies -f(x)-7=-|x|-7[/tex]
From inspection of the graph, we can see that it has been stretched parallel to the y-axis:
[tex]\implies -a\:f(x)-7=-a|x|-7[/tex]
The line goes through point (10, -10)
Substituting this point into the above equation to find [tex]a[/tex]:
[tex]\implies -a|10|-7=-10[/tex]
[tex]\implies -10a=-3[/tex]
[tex]\implies a=\dfrac{3}{10}[/tex]
Therefore,
[tex]\implies g(x)=-\dfrac{3}{10}|x|-7[/tex]

Answer:
Angle E equals 45 degrees and angle J equals 35 degrees.
If all angles of two triangles match up with one another, then you have yourself a pair of two similar triangles.
Hope it helps, have a fantastic day.
Step-by-step explanation:
We all know from geometry that all the angles of a triangle add up to 180 degrees.
We can form the following equation:
[tex]100 + 35 + E = 180[/tex]
[tex]E[/tex] here represents the measure of angle E.
Add together like terms:
[tex]135 +E = 180[/tex]
Then subtract 135 from both sides:
[tex]E = 45[/tex]
We can, likewise, form another equation for angle J :
[tex]100 + 45 + J = 180[/tex]
Add together like terms:
[tex]145 +J = 180[/tex]
Then subtract 145 from both sides:
[tex]J = 35[/tex]
Angle E equals 45 degrees and angle J equals 35 degrees.
If all angles of two triangles match up with one another, then you have yourself a pair of two similar triangles.
The power, P (watts), of a car engine is proportional to the square of its
speed, s(m/s). When s=25, P=1800. Work out the speed (to 1 DP) when the power is 2000 watts.
The speed when the power is 2000watts is 22.5m/s
Subject of formulaIf the power, P (watts), of a car engine is proportional to the square of its
speed, s(m/s), this is expressed as:
P = k/s
When s=25, P=1800 then;
1800 = k/25
k = 25 * 1800
k = 4500
In order to calculate the speed when the power is 2000;
s = k/p
s= 4500/2000
s = 22.5m/s
Hence the speed when the power is 2000watts is 22.5 m/s

john decides to buy a new laptop computer. it is on sale for 20% off and he has a coupon for 15% off the sale price. if sales tax is 6%, how much will john pay
The price that John would pay for the new laptop after accounting for the sales, price coupon and the sales tax is 0.72p.
What is the price John would pay?After the sales price and coupon is applied, the price of the laptop would reduce.
Price after the sales price = (1 - 0.2) x p = 0.8p
Price after the coupon = (1 - 0.15) x 0.8p
0.85 x 0.8p = 0.68p
A tax increases the price of the laptop.
Price after the tax = (1 + 0.06) x 0.68p = 1.06 x 0.68p = 0.72p

A straight line passes through the point (-1,2) and (2,8). Find the equation of the
straight line.
Answer:
Looking at the question, we are given two points and we need to determine the line that passes through both of these points. The first step to solving this problem is to find the slope.
[tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]slope=\frac{8-2}{2-(-1)}[/tex]
[tex]slope=\frac{6}{2+1}[/tex]
[tex]slope=\frac{6}{3}[/tex]
[tex]slope=2[/tex]
Now that we found the slope, we can move onto the next part which is to use the point-slope formula to determine our correct straight line.
[tex](y-y_1)=m(x-x_1)[/tex]
[tex](y-2)=2(x-(-1))[/tex]
[tex]y-2=2(x+1)[/tex]
[tex]y-2=2x + 2[/tex]
[tex]y- 2 + 2=2x + 2 + 2[/tex]
[tex]y=2x + 4[/tex]
Therefore, our straight line that passes through the two points that were provided in the problem is [tex]y=2x + 4[/tex].

Answer:
8.1. h = 17.743514416718 m 8.2. Area of ABCD = 112.912444233369 cm²Step-by-step explanation:
Q8.
Let h be the height of the flagpole
x be the distance between point P and the flagpole.
8.1.
tan(53) = h/x
⇒ h = xtan(53) (1)
On the other hand ,
tan(28) = h/(x+20)
⇒ h = (x+20)tan(28) (2)
Let’s equate equation so (1) and (2) :
⇒ xtan(53) = (x+20)tan(28)
⇒ x = 20tan(28) ÷ (tan(53) - tan(28)) = 13.370697151775
from (1) , we have :
h = xtan(53)
= 13.370697151775×tan(53)
= 17.743514416718
8.2.
Area ABCD = area ABD + area BCD
area ABD = (1/2) AB AD sin(BAD)
= (1÷2)×11×7×sin(110)
=36.178165900258
area BCD = (1/2) DB DC sin(BDC)
firsly , we need to calculate DB (using the law of cosines I need triangle ABD) :
DB² = AB² + AD² - 2AB AD cos(110)
= 11^2+7^2-2×11×7×cos(110)
= 222.671102072153
Then
DB = √(222,671102072153)
= 14.92216814247
Going back ,
area BCD = (1/2) DB DC sin(BDC)
= (1÷2)× (14,92216814247)×16×sin(40)
=76.734278333111
Conclusion :
Area ABCD = area ABD + area BCD
= 36.178165900258+ 76.734278333111
= 112.912444233369

If necessary, round your answer to the nearest whole number,
banana plants
The number of infected banana plants with a rate of 8% will be in 8 years is 848.
What is exponential growth or decay function?Consider the function:
y = a(1 + r)ˣ
where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.
A blight is spreading on a banana plantation. Currently, 458 banana plants are infected.
If the disease is spreading at a rate of 8% each year.
Then the number of the plants that will be infected in 8 years.
Then the exponential function is given as
y = 458(1.08)ˣ
At x = 8, then we have
y = 458(1.08)⁸
y = 458 x 1.851
y = 847.73
y ≅ 848
