Answer:
p = 3
Step-by-step explanation:
Given that x = - 4 is a zero then p(- 4) = 0, that is
p(x) = x² - 2x - (7p + 3), then
(- 4)² - 2(- 4) - 7p - 3 = 0, that is
16 + 8 - 7p - 3 = 0
21 - 7p = 0 ( subtract 21 from both sides )
- 7p = - 21 ( divide both sides by - 7 )
p = 3

calculate the surface area of each solid
with explanation
Answer:
602.88
Step-by-step explanation:
The two lids
Area = pi * r^2
d = 12
r = d/2
r = 12/2
r = 6 cm
Area = 3.14 * 6^2
Area = 3.14 * 36
Area = 113.04
Both Lids = 226.08
Cylinder Body
Circumference = 2*pi*r*h
Circumference = 2*3.14 *6 * 10 376.8
Total Area = 602.88

Answer:
7√2
Step-by-step explanation:
The triangle is a "special triangle", an isosceles right triangle. The side lengths of this triangle have the ratios 1 : 1 : √2. Multiplying these ratio values by 7, the length of the leg, you find ...
c = 7×√2
c = 7√2
_____
If you like, you can go through the Pythagorean theorem and/or trigonometry to find the same thing.
7/c = sin(45°)
c = 7/sin(45°) = 7/(1/√2) = 7√2
Or ...
c² = 7² + 7² = 98 . . . . using the Pythagorean theorem*
c = √98 = 7√2
__
* This requires you recognize the triangle is isosceles, so the other leg is also 7. Of course, you know that as soon as you see a 45° acute angle in a right triangle.

In 2011, a professional climber scaled the outside of the Burj Khalifa, making it all the way to 828 meters (the highest point on which a person can stand) in 6 hours.
Answer:
276 meters in the first 2 hours
Step-by-step explanation:
Given that,
Professional climbers climb 828 meters in 6 hours.
Let us assume we need to find how far did they climb in the first 2 hours.
6 hours = 828 m
⇒ 1 hour = 138 m
So, in 2 hours,
2 hours = 138 × 2 m
= 276 m
So, the climber climb 276 meters in the first 2 hours

question: turn the following system of equations into slope intercept form. (y=mx+b)
5x - 2y = -10
3x + 6y = 66
Answer:
y = 5/2x + 5
y = -1/2x + 11
Step-by-step explanation:
5x -2y = -10
-2y = - 5x -10
y = 5/2x + 5
3x + 6y = 66
6y = -3x + 66
y = -1/2x + 11

Step-by-step explanation:
Answer:
1/2 (option 1)
Step-by-step explanation:
the equation is in y=mx+b form (slope-intercept form)
y: y-axis
m: slope
x: variable
b: y-intercept
Points a and b both on line y=3x+7 work out the missing y coordinate for a and the missing x coordinate for b
Answer:
Missing [tex]y[/tex] coordinate for [tex]a[/tex] is [tex]3x+7[/tex]
Missing [tex]x[/tex] coordinate for [tex]b[/tex] is [tex]\frac{b-7}{3}[/tex]
Step-by-step explanation:
Given: Equation of a line is [tex]y=3x+7[/tex]
To find: missing [tex]y[/tex] coordinate for [tex]a[/tex] and the missing [tex]x[/tex] coordinate for [tex]b[/tex]
Solution:
First find missing [tex]y[/tex] coordinate for [tex]a[/tex]
Put [tex]x=a[/tex] in [tex]y=3x+7[/tex]
[tex]y=3(a)+7=3a+7[/tex]
Now find the missing [tex]x[/tex] coordinate for [tex]b[/tex]
Put [tex]y=b[/tex] in [tex]y=3x+7[/tex]
[tex]b=3x+7\\3x=b-7\\\\x=\frac{b-7}{3}[/tex]
Amanda bought tickets for a concert for $218. Jamie bought tickets to the same concert but paid 14% less than Amanda. What were the price of Jamie's tickets?
Answer:
Jamie's tickets = $187.48
Step-by-step explanation:
The amount for which Amanda bought tickets = $218
Jamie bought tickets to the same concert but paid 14% less than Amanda.
Jamie's tickets = [tex]218-14\%\ of\ 218[/tex]
We can solve it as follows :
[tex]218-14\%\ of\ 218=218-\dfrac{14}{100}\times 218\\\\=218-30.52\\\\=\$187.48[/tex]
So, the price of Jamie's tickets is $187.48.
Someone please help me?
Answer:
Option 2 (open circle at 6 with arrow going to the right.
Step-by-step explanation:
Open circle means "excluding that number". Since x>6, x cannot be 6 so we have an open circle at 6. x>6 also means x has to be greater than 6, so we have the arrow going to the right since 7 is greater than 6, 8 is greater than 6, and so on so forth.
Marcus purchased 4 1/2 pounds of rice on Monday and 2 1/3 pounds of rice on Tuesday, What was the total weight, in pounds, of rice purchased by Marcus in the two-day period?
A. 6 1/6
B. 6 2/5
C. 6 1/3
D. 6 5/6
E. 7 5/6
Answer:
he would have bought 6 5/6 pounds of rice.
Step-by-step explanation:
4 1/2 + 2 1/3 = ?
First, you want to get common dominaters. And the closest number is 6
4 3/6 + 2 2/6 = 6 5/6
This can not be simplifyed so that would be your answer.
The total weight, in pounds, of rice purchased by Marcus in the two-day period is [tex]6\frac{5}{6}[/tex] pounds.
Addition of fraction:It is given that,
Amount of rice purchased on Monday = [tex]4\frac{1}{2} pounds[/tex]
Amount of rice purchased on Tuesday[tex]=2\frac{1}{3} pounds[/tex]
the total weight, in pounds, of rice purchased by Marcus in the two-day period is computed as;
[tex]=4\frac{1}{2}+2\frac{1}{3} \\\\=\frac{9}{2} +\frac{7}{3} \\\\=\frac{27+14}{6} \\\\=\frac{41}{6}\\ \\=6\frac{5}{6} pounds[/tex]
Therefore, the total weight of rice is [tex]6\frac{5}{6}[/tex] pounds.

The total length of two ships is 2341 feet. The difference in their lengths is 13 feet.
a. Find the length of each ship.
b. If a football field has a length of 100 yards, determine the length of the longer ship in terms of football fields.
Answer:
The smaller ship is 1,164 ft
The larger ship is 1,177 ft
The larger ship is 3.923 football fields
Step-by-step explanation:
A. Find the length of each ship
x + x + 13 = 2,341 ft
2x + 13 = 2,341 ft
2x = 2,328 ft
x = 2,328/2
x = 1,164 ft ( This is the length of the smaller ship)
1,164 + 13 = 1,177 ft (length of the larger ship)
B)If a football field has a length of 100 yards, determine the length of the longer ship in terms of football fields.
1,177/3ft= 392.3 yards
392.3 yards /100 yards = 3.923 football fields

Answer:
Step-by-step explanation:
amount of discount = $10
percentage discount = $10/$39.99 ≅ 0.25 = 25%
amount of sales tax = $1.95
sales tax rate = $1.95/$29.99 ≅ 0.065 = 6.5%
cost of jeans × 1.60 = $39.99
cost of jeans = $39.99/1.60 ≅ $24.99
discounted selling price = $29.99
markup = $29.99/$24.99 ≅ 1.20 = 20%

Answer:
D (last one), [tex]x^2+y^2=45[/tex]
Step-by-step explanation:
We need to find the distance between (0,0) and (-3,6). Using the distance formula we get:
[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
[tex]d=\sqrt{\left(-3-0\right)^2+\left(6-0\right)^2}[/tex]
[tex]d=3\sqrt{5}[/tex]
Since equation of circle is: [tex]x^2+y^2=r^2[/tex] we have to square the distance we just found, which gives us 45.
Answer:
x^2 + y^2 = 45
Step-by-step explanation:
(x − a ) ^2 + ( y − b ) ^2 =r^2
= (-3-0)^(2)+(6-0)^(2)
