B. -94.94
Step-by-step explanation:
Substitute given value into function and evaluate
Answer:
-94.94
Step-by-step explanation:
The answer is -94.94. First you put -4.2 as x, so 23.2*-4.2 which gives you -97.44. Then you do (-97.44)+22.5. Which gives you the answer -94.94.

Approximate the sum of the first 17 terms to the nearest tenth.
Sum =

Step-by-step explanation:
The value [tex]a_1[/tex] is -256.
The value r = -1/4
What is a geometric sequence?A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.
Example:
2, 4, 8, 16 is a geometric sequence.
We have,
In a geometric sequence,
Each term is obtained by multiplying the preceding term by a constant factor, which is called the common ratio (r).
So,
The nth term of the sequence.
[tex]a_n[/tex] = -256 x [tex](-1/4){n-1}[/tex]
Now,
[tex]a_1[/tex] = -256 x [tex](-1/4)^{1 -1}[/tex]
= -256 [tex](-1/4)^0[/tex]
= -256 x 1
= -256
[tex]a_2[/tex] = -256 x [tex](-1/4)^{2-1}[/tex]
= -256 x [tex](-1/4)^1[/tex]
= -256 x -1/4
= 64
Now,
[tex]a_1[/tex] r = [tex]a_2[/tex]
-256 x r = 64
r = 64 / -256
r = -1/4
Therefore,
[tex]a_1[/tex]= -256 and r = -1/4

A carpenter cut a board that was 10 feet long into two pieces. The longer piece is 2 feet longer than three times the length of the shorter piece. What is the length of each piece?
Answer:
shorter piece: 2 feet
longer piece: 8 feet
Step-by-step explanation:
let the shorter piece be x
then the longer piece will be 3x + 2
if they join together:
3x + 2 + x = 104x + 2 = 104x = 10 -24x = 8x = 2Longer piece:

First, since it's given the angle PRS=98 degrees we can find x.
(3x-8)+(2x+6)=98 we can solve for x
after solving this we find that
x=20
Now we can solve for angle QRS
2x+6 plug in our values and we get
40+6, which equals 46 degrees

The area of a circle is 61.2cm2.
Find the length of the radius rounded to 2 DP.
Answer:
4.41 cm
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
61.2 = pi r^2
Using 3.14 for pi
61.2 / 3.14 = r^2
19.49044586 = r^2
Take the square root of each side
sqrt( 19.49044586) = sqrt(r^2)
4.414798507 = r
To 2 decimal places
4.41 = r

The isosceles triangle has a perimeter of 7. 5 m. Which equation can be used to find the value of x if the shortest side, y, measures 2. 1 m? 2 x minus 2. 1 equals 7. 5 4. 2 plus y equals 7. 5 y minus 4. 2 equals 7. 5 2. 1 plus 2 x equals 7. 5.
Using the perimeter formula of the Isosceles triangle the equation 2x + 2.1 = 7.5 is derived. The correct option is D.
What is the isosceles triangle?Triangle is a polygon that has three sides. The sum of the angle of the triangle is 180 degrees. The two sides of the triangle are equal.
Given
The isosceles triangle has a perimeter of 7.5 m.
We know the perimeter of the Isosceles triangle.
Perimeter = Sum of all sides of the triangle
Let the sides be x and y and
And let y be the shortest side.
For y = 2.1 m, the equation will be
[tex]\rm Perimeter = x + x +y\\[/tex]
On simplifying the equation, we get
2x + 2.1 = 7.5
The required equation is 2x + 2.1 = 7.5.
Thus, option D is correct.
