if the product (2x + 3)(x + k) is 2x^2 + 13x + 15, what is the value of k?
Answer: k = 5
(2x + 3)(x + k)
= 2x.x +2x.k + 3x + 3k
= 2x² + x(2k + 3) + 3k
because (2x + 3)(x + k) is 2x^2 + 13x + 15
=> 3k = 15
2k + 3 = 10
=> k = 5

y = 5x² + 3x
(Find the axis of symmetry and the vertex of the graph of the function)
Answer:
y = 5x² + 3x
(5x) x (5x) = 25x
y = 25x + 3x
25x + 3x = 28x
y =/= 28x

Some of Amber's daily activities are listed here. Use these descriptions to select the word or symbol that correctly completes each sentence. • Amber spends 3/16 of each day doing homework. • Amber spends 0.25 of each day at school. • Amber spends 1/3 of each day sleeping. (A) 3/16 of a day 0.25 of a day (B) 0.25 of a day 1/3 of a day (C) Amber spends time doing homework than she does at school. (D) Amber spends time sleeping than she does at school.
Answer: (D) Amber spends time sleeping than she does at school.
Step-by-step explanation:
Given that :
• Amber spends 3/16 of each day doing homework.
• Amber spends 0.25 of each day at school.
• Amber spends 1/3 of each day sleeping.
Hence,
Amber spends 0.1875 of a day doing homework, which is (0.1875 * 24) = 4.5 hours
0.25 of each day at school ; (0.25 * 24) = 6 hours
1/3 of each day sleeping ; (1/3 * 24) = 8 hours
Time spent sleeping = 8 hours
Time spent in school = 6 hours

The area of a rectangular park is same as area of a square park. If the length
of the rectangular park is 24.5 m and the side length of the square park is 14m,
find the breadth of the rectangular park?
Answer:
8mStep-by-step explanation:
Step one:
given data
length of rectangle= 24.5m
let the width be x
width of square= 14m
let the length be x
Step two:
we know that the area of a rectangle is
Ar= Length * width
Ar=24.5*x-----------1
Also, the area of the square is
As= Length * width
for square L=W
As= 14*14-----------------2
As=196m^2
equating 1 and 2 we have
14*14=24.5x
196=24.5x
divide both sides by 24.5
x=196/24.5
x=8m
The Breadth/width of the rectangular park is 8m

the soloutions to the equation 2x^2 + x - 1 = 2 are x= -3/2 or x=___
9514 1404 393
Answer:
x = 1
Step-by-step explanation:
Subtracting 2 puts the equation in standard form:
2x^2 +x -3 = 0
The product of the solutions is the ratio of the constant term to the leading coefficient: -3/2.
For solutions -3/2 and 'p', we have ...
-3/2p = -3/2
p = 1
The other solution is x = 1.

A rectangle has a length of 31 inches less than 3 times its width. If the area of the rectangle is 984 square inches, find the length of the rectangle.
Answer:
41 inches
Step-by-step explanation:
The formula for Area of a rectangle is ;
A = L × W
L = Length
W = Width
A rectangle has a length of 31 inches less than 3 times its width.
L = 3W - 31
If the area of the rectangle is 984 square inches, find the length of the rectangle
Hence,
984 = (3W - 31) × W
984 = 3W² - 31W
Hence
3W² - 31W - 984
3W(W - 24) + 4(W - 24) = 0
(3W + 41)(W - 24) = 0
W - 24 = 0
W = 24 inches
We have to find the Length
L = 3W - 31
L = 3(24) - 31
L = 72 - 31
L = 41 inches
The Length = 41 inches
The Length of the rectangle is 41 inches

The mean undergraduate cost for tuition, room, board and fees for four-year colleges in the United States was found to be $26,489, with a standard deviation of $3204. If 36 of the four-year colleges are randomly sampled, find the probability that the mean cost for the sample schools is:
Answer:
0.1787
Step-by-step explanation:
It is given that the mean cost of undergraduate program for a four year institutions for tuition, rooms fees and board was =$26,489
And the minimum standard deviation is given as σ = $ 3204
So, the mean normal deviation is , μ = 26,489
and the standard deviation is, σ = 3204
Thus, the probability of the mean cost for sample schools is 0.1787
The distance from Houston to
Galveston is about 50 miles. If there are
1.6 kilometers in a mile, what is the
distance from Houston to Galveston in
kilometers?
Answer:
distance from Houston to Galveston in kilometers will be: 80km
Step-by-step explanation:
Given
The distance from Houston to Galveston is about 50 miles.
i.e.
Kilometers in 1 Mile = 1.6 km
As the distance from Houston to Galveston is about 50 miles, so
The distance from Houston to Galveston in kilometers will be:
50(1.6) = 80 ∵ Kilometers in 1 Mile = 1.6 km
Therefore,
The distance from Houston to Galveston in kilometers will be: 80km
8 – 3(4x - 1) >= -49
Answer:
x≤61/12
Step-by-step explanation:
distribute the -3
8-12x+3≥-49
add like terms
12-12x≥-49
subtract 12 from both sides
-12x≥-61
divide by -12, when you divide by a neg the lessthan/greaterthan sign flips
x≤61/12
"-3 = 9/5c + 32" help with finding c pls!! i need it as a decimal btw.
Answer:
-3=9/5c +32
-3*5c=9/5c*5c+32*5c
-15c=9+160c
-15c -160c =9
c(-15-160)=9
c(-15-160)/(-15-160)=9/(-15-160)
c=9/(-15-160)
