Answer:
8.5
Step-by-step explanation:
QR is 10
PQRS AREA is 45
10 times 4.5 is 45
meaning BC and PQ is 4.5
4.5 plus 4.5 is 9
26 minus 9 is 17
17 divided by two is 8.5
AB is 8.5
What is the slope of the graph shown below
Answer:
B=-5
Step-by-step explanation:
Slope=rise/run
The line passes in
P1(-1,3)
and
P2(0,-2)
So slope=(3-(-2))/(-1-0)=5/-1=-5

consider the two triangles shown below are the two triangles congruent
Answer: Yes
Step-by-step explanation: Let's first find the missing angle in the second triangle and to find this angle, remember that the sum of the measures of a triangle is 180 degrees so you should find that our missing angle is 67°.
Now, notice that we have two angles and the included side of one triangle
congruent to two angles and the included side of a second triangle.
Therefore, we can say the triangles are congruent by ASA.

prices varied on the seating arrangements and cost $8, $10, or $12. The
total income from ticket sales reached $3920. If the combined number
of $8 and $10 priced tickets sold was 5 times the number of $12 tickets
sold, how many tickets of each type were sold?

In a circle, chords ST and RA intersect at Y such that SY is perpendicular to RY. The value of mSA + mRT is: a. 90º b. 180º c. 225º d. Undefined
Answer:
a. 90º
Explanation:
The chords ST and RA intesect at Y, so that SY is now perpendicular to RY and they form an angle 90 degrees at that point. However angles mSA and mRT are both at the circumference of the circle(a chord is a line from point of a circle's circumference to the other) and are both 90 degrees because angle at the circumference is half of angle at the centre in same arc.

A corporate team-building event cost $4, plus an additional $3 per attendee. If there are 39 attendees, how much will the corporate team-building cost?
Answer:
$121
Step-by-step explanation:
Find how much additional money it will cost from the attendees:
39(3)
= 117
Add the other $4:
117 + 4
= 121
So, it will cost $121
Sam studied guinea pigs for his science fair project. He found that the amount of weight the guinea pigs gained varied directly with the number of calories they consumed.
The guinea pigs gained 1 ounce for every additional 218 calories in their diet. How many additional ounces would they gain if their diet was increased by 1,090 calories? Let W represent the weight in ounces, and let C represent the number of calories.
Answer: C= 1,090 and the W= 5.

9514 1404 393
Explanation:
This is an identity.
cos²(A) +cos²(A)cot²(A) = cot²(A)
Transforming the left side, we have ...
= cos²(A)(1 +cot²(A))
= cos²(A)csc²(A)
= (cos(A)/sin(A))²
= cot²(A)
Como Determinar a equação da reta que passa pelos pontos A(-1, -2) e B(5,2)
Answer:
A equação da reta é dada por: [tex]y = \frac{2}{3}x - \frac{4}{3}[/tex]
Step-by-step explanation:
Equação de uma reta:
A equação de uma reta tem o seguinte formato:
[tex]y = ax + b[/tex]
Em que a é o coeficiente angular e b é o coeficiente linear.
Coeficiente angular:
Com posse de dois pontos, o coeficiente angular é dado pela mudança em y dividida pela mudança em x.
A(-1, -2) e B(5,2)
Mudança em y: 2 - (-2) = 2 + 2 = 4
Mudança em x: 5 - (-1) = 5 + 1 = 6
Coeficiente angular: [tex]m = \frac{4}{6} = \frac{2}{3}[/tex]
Então:
[tex]y = \frac{2}{3}x + b[/tex]
Coeficiente linear:
Substituindo um ponto na equação, encontra-se o coeficiente linear.
B(5,2)
Quando [tex]x = 5, y = 2[/tex]. Então:
[tex]y = \frac{2}{3}x + b[/tex]
[tex]2 = \frac{2}{3}5 + b[/tex]
[tex]b = 2 - \frac{10}{3} = \frac{6}{3} - \frac{10}{3} = -\frac{4}{3}[/tex]
Então:
[tex]y = \frac{2}{3}x - \frac{4}{3}[/tex]
What is the least possible value of (x +1)(x+2)(x+3)(x +4)+2019 where x is a real
number?
MANY POINTS
Answer:
f(x)=(x+1)(x+2)(x+3)(x+4)+2019
f(x)=(x2+5x+4)(x2+5x+6)+2019
Suppose that y=x2+5x
Hence we have f(y)f(y)=(y+4)(y+6)+2019=y2+10y+24+2019=y2+10y+25+2018=(y+5)2+2018≥2018[∵(y+5)2≥0,∀y∈R]
and therefore…. min (f(x))=2018
ANSWER = 2018
Step-by-step explanation:
hope that helps >3
Answer:
2018
Step-by-step explanation:
By grouping the first, last and two middle terms, we get ([tex]x^{2}[/tex]+5x+4)([tex]x^{2}[/tex]+5x+6) + 2019. This can then be simplified to ([tex]x^{2}[/tex]+5x+2)^2 - 1 + 2019 Noting that squares are nonnegative, and verifying that [tex]x^{2}[/tex] + 5x + 5 = 0 for some real x, the answer is 2018.

Answer:
40
Step-by-step explanation:
A+B+C = 31
Add 3 years to each age
A+3 +B+3 + C+3 = 31 +3+3+3
They will be
A+3 +B+3 + C+3 = 40
Answer:
it will be 40
Step-by-step explanation:
If they are altogether 31 years old now in 3 years we just add 9 thus it is 40
If < A and < B are supplementary, and < A = 3x - 9 degrees, and < B = 2x + 14 degrees, find x.
Select one:
a. 19
b. 84
c. 35
d. 24
Answer:
Option c, 35
Step-by-step explanation:
<A and <B are supplementary,
so, <A+<B = 180
or, 3x-9+2x+14=180
or, 5x+5=180
or, 5x=175
or, x=35

A new car sells for $25,000. The value of the car decreases by 15% each year. What is the approximate value of the car 5 years after it is purchased? 25,000 (1 minus 0.15) Superscript 5, or approximately $11,093 25,000 minus 1500 (5), or approximately $17,500 25,000 (0.15) Superscript 5, or approximately $18,984 25,000 minus left-bracket (100 minus 15) (5) Right-bracket, or approximately $24,575
Answer:
A. 25,000 (1 minus 0.15) Superscript 5, or approximately $11,093
Step-by-step explanation:
A. 25,000 (1 minus 0.15) Superscript 5, or approximately $11,093
B. 25,000 minus 1500 (5), or approximately $17,500
C. 25,000 (0.15) Superscript 5, or approximately $18,984
D. 25,000 minus left-bracket (100 minus 15) (5) Right-bracket, or approximately $24,575
Value of the car = $25,000
Percentage decrease per year = 15%
Value after 5 years
Total percentage value of the car = 100%
Percentage value remaining each year = (100% - 15%)
= (1 - 0.15)
Decrease of the car in the next 5 years = $25,000(1 - 0.15)^5
= $25,000(0.85)^5
= $25,000(0.4437053125)
= $11,092.6328125
Approximately = $11.093
Value of the car in the next 5 years = $25,000 - $11,093
= $13,907

It's A, $11,093

x^2 + 10× - 2400 = 0
Answer:
x= -5 + 5[tex]\sqrt{97}[/tex], x= -5 - 5[tex]\sqrt{97}[/tex]
Step-by-step explanation:
Since this quadratic is set to zero, we can use the quadratic formula to solve this.
x^2 + 10x - 2400 = 0
Quadractic formula = x= -b +- [tex]\sqrt{b^2 - 4ac}[/tex] /2a
For this equation:
a= 1, b=10, c=-2400
Plug these numbers into the equation and solve.
x= -10 +- [tex]\sqrt{10^2 - 4(1)(-2400}[/tex])/2(1)
x= -10 +- [tex]\sqrt{100 + 9,600}[/tex]/2
x= -10 +- [tex]\sqrt{9,700}[/tex]/2
x= -10 +- [tex]\sqrt{2^2 * 5^2 * 97}[/tex]/2
x= -10 +- 5 * 2[tex]\sqrt{97}[/tex]/2
x= -10 +- 10[tex]\sqrt{97}[/tex] / 2
Divide by 2.
x= -5 +- 5[tex]\sqrt{97}[/tex]
Answer:
x= -5 + 5[tex]\sqrt{97}[/tex] or x= -5 - 5[tex]\sqrt{97}[/tex]
Solve the equation and enter the value of x below. -4(x - 5) = 60
Answer:
The value of x is 10.
Step-by-step explanation:
By question,
-4(x - 5) = 60
or,-4x + 20 = 60
or,-4x = 60 -20
or, -4x = 40
or, x =40/-4
Hence,x=10
Answer:
x = 10
Step-by-step explanation:
-4(x - 5 ) = 60
Solve for x.
-4(x - 5 ) = 60
Step 1 :- Distribute -4.
-4 × x - 4 × -5 = 60
-4x + 20 = 60
Step 2 :- Move constant to the right-hand side and change their sign.
-4x = 60 - 20
Step 3 :- Subtract 20 from 60.
-4x = 40
Step 4 :- Divide both side by -4.
[tex] \frac{ - 4x}{ - 4} = \frac{40}{ - 4} \\ [/tex]
Hence , x = 10

for the columns where is less than or equal zero, use the first line of the function to calculate the value of f(x)
[tex] { ( \frac{1}{3} ) }^{ - 2} - 1 = 9 - 1 = 8 \\ { ( \frac{1}{3} ) }^{ - 1} - 1 = 3 - 1 = 2 \\ { ( \frac{1}{3} ) }^{ 0} - 1 = 1 - 1 = 0[/tex]
for every x greater than zero, use the second line to determine the value
[tex] {3}^{1} - 2 = 3 - 2 = 1 \\ {3}^{2} - 2 = 9 - 2 = 7[/tex]
