Answer:
5, 8, 11
Step-by-step explanation:
To find the first 3 terms substitute n = 1, 2, 3 into n th term rule, that is
a₁ = 3(1) + 2 = 3 + 2 = 5
a₂ = 3(2) + 2 = 6 + 2 = 8
a₃ = 3(3) + 2 = 9 + 2 = 11
The first 3 terms are 5, 8, 11
What are roots of (3x+7)(2x-5)=0
Answer:
x = - [tex]\frac{7}{3}[/tex] , x = [tex]\frac{5}{2}[/tex]
Step-by-step explanation:
Given
(3x + 7)(2x - 5) = 0
Equate each factor to zero and solve for x
3x + 7 = 0 ( subtract 7 from both sides )
3x = - 7 ( divide both sides by 3 )
x = - [tex]\frac{7}{3}[/tex]
and
2x - 5 = 0 ( add 5 to both sides )
2x = 5 ( divide both sides by 2 )
x = [tex]\frac{5}{2}[/tex]
Carrie drew a scale drawing of the auditorium. The stage is 3 inches wide in the drawing. The actual stage is 30 feet wide. What scale did Carrie use for the drawing?
Answer:
1 : 120
Step-by-step explanation:
Given that ;
Actual width = 30feets
Width in drawing = 3 inches
Recall :
1 foot = 12 inches
Actual width in inches : (30 * 12) = 360 inches
Comparing actual width to drawing width
3 inches : 360 inches
1 : 120
Scale used is :
1 : 120

a coin is flipped and a six-sided die, numbered 1 to 6, is rolled. find the probability of flipping tails and rolling a number less than 3
Answer:
5/6
Step-by-step explanation:
There is a 1 out of 2 chance that you will roll tails, so the probability is 1/2.
A number less than three is a 2 and 1, so the probability is 2/6.
Add 1/2 + 2/6. (Change 1/2 to 3/6 so you can add.)
3/6 + 2/6 = 5/6

A zucchini plant in Darnell’s garden was 12 centimeters tall when it was first planted. Since then, it has grown approximately 0.5 centimeter per day.
a. Write a rule to describe the function.
b. After how many days will the zucchini plant be 0.195 meter tall?
A. h(d) = 12d + 0.5; 1.3 days
B. h(d) = [tex]\frac{d}{0.5}[/tex]+12; 4 days
C. h(d) = 0.5d; 39 days
D. h(d) = 0.5d +12; 15 days
Answer:
a) 12 + 0.5d d=day
b) 0.195/0.5=0.39d
Step-by-step explanation:
Answer
(a) Find out the a rule to describe the function.
To prove
Let us assume that the days be represted by d .
Let us assume that the height of plant be represted by y.
As given
A zucchini plant in Darnell’s garden was 12 centimeters tall when it was first planted.
it has grown approximately 0.5 centimeter per day.
Than the function becomes
y = 12 + 0.5 × d
y = 12 + 0.5d
(b) Find out after how many days will the zucchini plant be 0.195 meter tall .
To prove
Let us assume that the days be represted by d .
As given
A zucchini plant in Darnell’s garden was 12 centimeters tall when it was first planted.
it has grown approximately 0.5 centimeter per day.
As
1meter = 100cm
0.195 meter convert into centimeter.
= 19.5cm
Than the equation becomes
12 + 0.5d = 19.5
0.5d = -12 + 19.5
0.5d = 7.5
d = 15 days
Therefore 15 days will the zucchini plant be 0.195 meter tall .

what is area how do you find the area if a rectangle
Answer: To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
Step-by-step explanation:
Answer:
If it is a rectangle you just do A=w*h
width times height
you don't have a picture showing the rectangle so I can't find the area

3. The figure below is a composite shape that consists of a semicircle and an equilateral triangle (triangle
with sides that are all equal). Find the perimeter and area of the composite shape. Use 3.14 for pi.
Perimeter:
4cm
5cm
Area:
Answer:
See explanation below
Step-by-step explanation:
Area = Area of triangle + Area of the semi circle
Area of triangle = 1/2bh
Area of triangle = 1/2 *(5/2)(4)
Area of triangle = 1/2(2.5)*4
Area of triangle = 2 * 2.5
Area of triangle = 5cm^2
Area of semicircle = πr²/2
r = 2.5cm
Area of semicircle =(3.14)(2.5)²/2
Area of semicircle = = 3.14 * 4.5
Area of semicircle = 9.8125cm^2
Area pf the figure = 5+9.8125
Area pf the figure = 14.8125cm^2
For the perimeter
Perimeter of the semicircle = 2πr
Perimeter of the semicircle = 2(3.14)(2.5)
Perimeter of the semicircle = 15.7cm
Perimeter of the semicircle = = 15.7 + 5 + 5
Perimeter of the semicircle = 25.7cm

Slope intercept form of points 0, -4 and -1, 4
Answer:
[tex]y=\frac{0}{-1} -4[/tex]
Step-by-step explanation:
first, you have to find the slope, and to do that you use this equation [tex]\frac{y2-y1}{x2-x1}[/tex]
so, now to insert your points (0,-4), (-1,4)
(x1,y1) (x2,y2)
[tex]\frac{4-4}{-1-0} = \frac{0}{-1}[/tex]
now that you have the slope you can find the y-intercept of the slope-intercept form by looking at your first point (0,-4) and get -4
- if you were to look at this point on a graph it would be on the y-axis therefore, -4 is the y-intercept [if you don't have a point like this one then you can look at a graph with one of your points and make a slope until you are on the y-axis :)]
therefore, the slope-intercept form is y=[tex]\frac{0}{-1}[/tex] -4
[ps, your slope is a zero slope :)]
Answer:
y = - 8x - 4
Step-by-step explanation:
y = mx + b
"m" is slope, "b" is y-intercept.
( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )
( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
~~~~~~~~~~~~~~~
(0, - 4) are coordinates of y-intercept.
( - 1, 4)
m = [tex]\frac{4 + 4}{-1-0}[/tex] = - 8
y = - 8x - 4

[tex] - 32[/tex]
Step-by-step explanation:
1) Simplify
[tex] \sqrt{32} \: to \: 4 \sqrt{2} [/tex]
[tex] - 8 \sqrt{2} \times \frac{1}{2} \times 4 \sqrt{2} [/tex]
2) Use this formula: a/b × c/d = ac/bd.
[tex] - \frac{8 \sqrt{2} \times 1 \times 4 \sqrt{2} }{2} [/tex]
3) Simplify.
[tex] - \frac{32 \sqrt{2 \sqrt{2} } }{2} [/tex]
4)
[tex]simplify \: 32 \sqrt{2 } \sqrt{2} \: to \: 32 \sqrt{4} [/tex]
5) Since 2 × 2 = 4, the square root of 4 is 2.
[tex] - \frac{32 \times 2}{2} [/tex]
6) Simplify 32 × 2 to 64.
[tex] - \frac{64}{2} [/tex]
7) Simplify 64/2 to 32.
[tex] - 32[/tex]
Therefor, the answer is option three -32
A rectangular lawn 40 m by 20 m is surrounded all around outside by a path which is 3 m wide. The area of the path is _____ sq. m
Answer:
The area of the path is 626 square meters.
Step-by-step explanation:
Area of ABCD (of the rectangle)
Given length = 40m
Given breadth = 20m
Area = Length × breadth
= 40m × 20m
= 800m^2
External path = 3m wide
Length =40m+3m+3m=46m
Breadth = 25m+3m+3m= 31m
Area of PQRS= Length × breadth
46m ×31m = 1426m^2
Area of path = Area of PQRS - Area of ABCD
= 1426m^2 - 800m^2
= 626m^2
The area of the path is 626 square meters.
hope this helps :)
