What are the zeros of the function and what is the vertex of the parabola?
Answer: [tex]-4,-15;\ \left(-\dfrac{19}{2},-\dfrac{121}{4}\right)[/tex]
Step-by-step explanation:
Given
Function is [tex]F(t)=t^2+19+60[/tex]
Zeroes of the function are
[tex]t^2+19t+60=0\\\\\Rightarrow t=\dfrac{-19\pm\sqrt{19^2-4\times 1\times 60}}{2\times 1}\\\\\Rightarrow t=\dfrac{-19\pm \sqrt{121}}{2}\\\\\Rightarrow t=\dfrac{-19\pm 11}{2}\\\\\Rightarrow t=-4,-15[/tex]
Using completing the square method
[tex]y=t^2+2\times \dfrac{19}{2}t+\dfrac{19^2}{2^2}-\dfrac{19^2}{2^2}+60\\\\y=\left(t+\dfrac{19}{2}\right)^2+60-\dfrac{361}{4}\\\\y=\left(t+\dfrac{19}{2}\right)^2-\dfrac{121}{4}\\\\y+\dfrac{121}{4}=\left(t+\dfrac{19}{2}\right)^2\\\\\left(y-(-\dfrac{121}{4}\right)=\left(t-(-\dfrac{19}{2})\right)^2\\\\\text{The vertex is }\left(-\dfrac{19}{2},-\dfrac{121}{4}\right)[/tex]

Di cuantos ejos de simetria tiene un poligono regular segun su nombre de lados. Cuales elementos del poligono coresponden a ejos simetria?
A certain triangle, one angle measures ten degrees more than the second angle and ten degrees less than the third angle. What is the measure of the smallest angle?
Answer:
50°
Step-by-step explanation:
Let :
Let the angle = x
Second angle = x + 10
Third angle = x - 10
Sum of angles in a triangle = 180
x + (x + 10) + (x - 10) = 180
x + x + 10 + x - 10 = 180
3x = 180
x = 180 / 3
x = 60
Smallest angle :
x - 10 = 60 - 10 = 50°
Find the value or measure below. Assume that lines that appear tangent to be tangent.
Answer:
x = 11.2
Step-by-step explanation:
hypotenuse = 8.4 (radius) + 5.6 = 14
using the Pythagorean theorem:
x² = 14² - 8.4² = 196 - 70.56 =125.44
x = √125.44 = 11.2

The graph of inequality that represents the scenario is graph (b)
The given parameters are:
People signed up = 4
People needed = At least 9
Represent the number of people who are still needed with x.
So, we have the following inequality expression
[tex]x + 4 \ge 9[/tex]
Subtract 4 from both sides
[tex]x \ge 5[/tex]
The above means that, 5 or more people are still needed
The graph of inequality that represents [tex]x \ge 5[/tex] is graph (b)

Find (a) PQ to the nearest tenth and (b) the coordinates of the midpoint of __ pq.
Answer:
a) 5units
b) (4.5, 4)
Step-by-step explanation:
Let the coordinate of P and Q be P(3, 2) and Q(6, 6)
PQ can be gotten using the distance formula;
PQ =√(6-2)²+(6-3)²
PQ = √4²+3²
PQ =√16+9
PQ =√25
PQ = 5units
Midpoint M is expressed as;
M(X, Y) = {(x1+x2)/2, y1+y2/2}
X = x1+x2/2
X = 3+6/2
X= 9/2
X = 4.5
Similarly;
Y = y1+y2/2
Y = 2+6/2
Y = 8/2
Y = 4
Hence the midpoint of PQ is (4.5, 4)
Please help with the mean, median and range, look at the picture!
Answer:
Mean: 39 Median: 32.5 Range: 62
Step-by-step explanation:
First, you organize the numbers from least to greatest, so 10 15 19 46 72 72. The median is the middle number, so the average of 19 and 46( 32.5). The Range is the largest number minus the smallest number, so 62. and the mean is all the numbers added up, then divided by the amount of numbers, so 234/6 or 39.

Answer: A
Step-by-step explanation:
The maximum amount of weight the truck can carry is 1600lbs. You do not want to exceed 1600lbs, but you can reach 1600lbs. This makes the inequality symbol ≤. This symbol says that the weight load has to be less than 1600lbs, but It can equal 1600lbs. You know that the piano is 400lbs and each box is 50lbs. Since you want to figure out how many boxes you can put on the truck alongside the piano, you can use the inequality: 50x + 400 ≤ 1600.
50 represents pounds per/box
x represents the number of boxes you can hold
400 represents the weight of the piano
1600 represents the max weight.

The statements that are necessary and sufficient to prove that ABCD is a parallelogram are, (B), (C) and (D).
What is a parallelogram?A basic quadrilateral with two sets of parallel sides is known as a parallelogram. In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size.
The area of a parallelogram is base multiples by height as two triangles form a parallelogram.
From the properties of parallelograms the statements that are necessary and sufficient to prove that ABCD is a parallelogram are,
[tex]\overline{AE}[/tex] ≅ [tex]\overline{CE}[/tex] and [tex]\overline{BE}[/tex] ≅ [tex]\overline{DE}[/tex] as diagonal of a parallelogram bisect each other.
[tex]\overline{AB}[/tex] ≅ [tex]\overline{CD}[/tex] and [tex]\overline{BE}[/tex] ≅ [tex]\overline{CE}[/tex] opposite sides of a parallelogram are equal.
m∠ABC + m∠BAD is 180° as the sum of the adjacent sides in a parallelogram are supplementary.

Given:
The right angle triangle with legs 4 units and 7 units.
To find:
The length of hypotenuse.
Solution:
Pythagoras theorem: In a right angle triangle,
[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]
Let x be the length of the hypotenuse.
Using the Pythagoras theorem for the given triangle, we get
[tex]x^2=4^2+7^2[/tex]
[tex]x^2=16+49[/tex]
[tex]x^2=65[/tex]
Taking square root on both sides, we get
[tex]x=\sqrt{65}[/tex] [∵Side length cannot be negative]
[tex]x\approx 8.06[/tex]
Therefore, the length of the missing side for the given right angle triangle is 8.06 units.
In school, Philip learned that the average person produces 50 pounds of recyclables every month. But, they usually throw away twice that much garbage. He wonders what that means for his family. Philip lives with his mother, father, and 2 sisters. About how many tons of garbage does Philip's family throw away every year?
Answer:
6000 tons
Step-by-step explanation:
dirt thrown by one person = 50 x 2 = 100
there are 5 people in the home
dirt thrown by the family in a month = 100 x 5 = 500
In a year = 500 x 12 = 6000
