Evaluate using the functions f(x) = 3x–8 and g(x) = -x2+ 4x–11.
1 . f(10+10
2. g(-9)+7
3. -2xg(4)
4. f(-4)-g(7)
5. Given f(x)= 9 –2x, if f(x)= 19, find the value of x.
The value of f(10)+10 for the given function is 32.
The given functions are f(x) = 3x-8 and g(x) = -x²+ 4x-11.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
1) Put x=10 in the function f(x) = 3x-8, we get
f(10)=3(10)-8
= 22
So, f(10)+10
= 22+10=32
2) Put x=-9 in the function g(x) = -x²+ 4x-11, we get
g(-9)=-(-9)²+4(-9)-11
= -81-36-11
= -128
So, g(-9)+7
= -128+7
= -121
3) Put x=4 in the function g(x) = -x²+ 4x-11, we get
g(4) = -(4)²+4(4)-11
=-16+16-11
=-11
Now, -2xg(4) =-2x(-11)
=22x
4) Put x=-4 in the function f(x) = 3x-8, we get
(-4)=3(-4)-8
= -20
Put x=7 in the function g(x) = -x²+ 4x-11, we get
g(7)=-(7)²+4(7)-11
= -49+28-11
= -32
5. Given f(x)= 9 –2x, if f(x)= 19
Now, 9-2x=19
⇒ -2x=10
⇒ x=-5
Therefore, the value of f(10)+10 for the given function is 32.

You are taking a trip at the same time as another
family. Your family traveled 1.900 miles in 2 days,
their family traveled 2.700 miles in 3 days. Who is
traveling fastera
Answer:
My family is traveling faster, since it is traveling at the rate of 950 miles per day, while the other family travels at 900 miles per day.
Step-by-step explanation:
Since I am taking a trip at the same time as another family, and my family traveled 1,900 miles in 2 days, while their family traveled 2,700 miles in 3 days, to determine who is traveling faster the following calculation must be performed:
1,900 / 2 = 950
2,700 / 3 = 900
Thus, my family is traveling faster, since it is traveling at the rate of 950 miles per day, while the other family travels at 900 miles per day.

Answer:
(x+9)^2+(y+5)^2=81
Step-by-step explanation:
(x-h)^2+(y-k)^2=r^2
(h,k)=center
r=radius
so if you just insert the center (-9,-5) and the r with 9
(x-(-9))^2+(y-(-5))^2=9^2
(x+9)^2+(y+5)^2=81

Find the areas of these parallelograms, drawn on a centimetre grid.
b)
a)
Answer:
a-16cm
b-12cm if not iwill look again
Step-by-step explanation:
Area of the parallelograms are :(a) = 16 cm² and (b) = 12 cm² which is drawn on a centimeter grid.
What is Parallelogram?A parallelogram is defined as a special type of quadrilateral that has both pairs of opposite sides parallel and equal. A parallelogram is a square and a rhombus is a square.
The formula to calculate the area of a parallelogram can thus be given as,
Area of parallelogram = b × h square units
where b is the length of the base and h is the height or altitude
For parallelogram (a),
length of the base = 4 cm
the height or altitude = 4 cm
Area of parallelogram (a) = b × h = 4 × 4
Area of parallelogram (a) = 16 cm²
For parallelogram (b),
length of the base = 2 cm
the height or altitude = 6 cm
Area of parallelogram (b) = b × h = 2 × 6
Area of parallelogram (b) = 12 cm²

The height of the diane when the height of euardo and diane cast should be given so it should be 5.5.
Calculation of the height:Since
HEIGHT Eduardo is 6 feet tall and casts a 12-foot shadow. At the same time, Diane casts an 11-foot shadow.
So,
6 feet tall = 12
Now for 11 foot it should be half like 5.5
