For triangle GTL
h²=p²+b²
or, 13²=p²+12²
or, 169=p²+144
or, p²= 25
or, p=5
so, GT = 5
now
for triangles GTL and GTJ
<GTL=<GTJ(both are 90° because GT is perpendicular to JL)
<JGT=<LGT=90° (GT is perpendicular to JL so it bisects G)
GT=GT(common)
so
triangles GTL and GTJ is congruent by A.S.A axiom
JT=12(correspong side of congruent ttriangle are equal)
now
JG= 13(corresponding side of congruent triangles are equal)
now
for triangle JGT, it is a right angled triangle as <JGT = 90°)
Let <JGT be G.
tanG=p/b
or, tanG=12/5
G= 67.4°
<JGT=67.4°
now
<JGR=<JGT=67.4°(JG is at midpoint bisecting <RGT)
in JGR,
<JRG=90°(RG is perpendicular to JK as <GRK is 90°)
now
JGR is a right angled triangle so
cosG=b/h
or, cos67.4=(x-3)/13
or, cos67.4(13)=x-3
or, 4.99=x-3
or, 5 = x-3
so, x = 5+3
so, x = 8
Hi!! When we do percents could decimal way be sufficient or will fraction way be?
Answer:

Step-by-step explanation:
shows some values of a linear function f and an exponential function g. find exact values (not decimal approximations) for each of the missing entries. x 0 1 2 3 4 f(x) 10 ? 20 ? ? g(x) 10 ? 20 ? ?
The missing entries for f(x) are 20, 30, and 40, and the missing entries for g(x) are 40, 80, and 160.
The missing entries for f(x) can be found by knowing that f is a linear function and using the values given. A linear function has the form f(x) = ax + b, where a is the slope and b is the y-intercept. Since f(0) = 10 and f(1) = 20, we can use these two points to find a and b.
Putting x = 0 in the equation, we get:
f(0) = 10 = a(0) + b
Putting x = 1 in the equation, we get:
f(1) = 20 = a(1) + b
Solving these two equations simultaneously, we find:
a = 10
b = 0
So, the equation for f is:
f(x) = 10x + 0 = 10x
Using this equation, we can find the missing entries for f(x) in the table:
f(2) = 10x = 10(2) = 20
f(3) = 10x = 10(3) = 30
f(4) = 10x = 10(4) = 40
So the missing entries for f(x) are 20, 30, and 40.
To find the missing entries for g(x), we need to know the form of the exponential function g. A common form for exponential functions is g(x) = ab^x, where a is the y-intercept and b is the growth factor. Since g(0) = 10 and g(1) = 20, we can use these two points to find a and b.
Putting x = 0 in the equation, we get:
g(0) = 10 = a(1)^0 = a
So, a = 10.
Putting x = 1 in the equation, we get:
g(1) = 20 = 10b
Solving for b, we find:
b = 2
So, the equation for g is:
g(x) = 10(2^x)
Using this equation, we can find the missing entries for g(x) in the table:
g(2) = 10(2^2) = 10(4) = 40
g(3) = 10(2^3) = 10(8) = 80
g(4) = 10(2^4) = 10(16) = 160
So the missing entries for g(x) are 40, 80, and 160.

Which figure is a translation of figure 1?
Answer:
triangle 4.
Step-by-step explanation:
A translation only moves vertically or (and) horizontally our image.
This means that a translation does not change the size
A translation does not rotate the image.
Then a translation of triangle 1 needs to have the same size than triangle 1, and the same "direction" (in triangle 1 we can see that the hypotenuse is at the right side, then in the translated triangle we also should have the hypotenuse at the right side).
Then the only option that seems correct is triangle 4

Answer:
BA ≈ 410.1 m
Step-by-step explanation:
using the tangent ratio in the right triangle
tan34° = \(\frac{opposite}{adjacent}\) = \(\frac{BA}{BC}\) = \(\frac{BA}{608}\) ( multiply both sides by 608 )

he highest recorded temperaturein the world was 38.0\deg C in El Azizia , Libya, on September 13, 1922. Calculate in degrees farenheit.
The highest recorded temperature in the world, 38.0°C in El Azizia, Libya, on September 13, 1922, is equivalent to 100.4°F.
The Fahrenheit scale divides the temperature range between these two points into 180 equal divisions or degrees. Each degree Fahrenheit is 1/180th of the temperature difference between the freezing and boiling points of water.
To convert Celsius to Fahrenheit, we use the formula:
°F = (°C × 9/5) + 32
Given that the temperature is 38.0°C, we can substitute this value into the formula:
°F = (38.0 × 9/5) + 32
°F = (342/5) + 32
°F = 68.4 + 32
°F = 100.4
Therefore, the highest recorded temperature in El Azizia, Libya, on September 13, 1922, was 100.4°F.

Use the image to answer the question. A coordinate plane with four quadrants shows the x- and y-axes ranging from negative 5 to 5 in increments of 1. A solid line and a dotted line intersect each other. The equation of the solid line is x minus 5 y equals 3. The equation of the dotted line is 3 x minus 2 y equals negative 4. The intersection of both lines is shown at negative 2 on the x-axis and negative 1 on the y-axis in quadrant 3.
Review the graphs of a system of two linear equations in two variables: x−5y=7 and 3x−2y=−4. Find the solution to both equations.(1 point)
The intersection point is ()
The equations given are x - 5y = 3 and 3x - 2y = -4. To find the solution to this system of equations, we need to find the values of x and y that satisfy both equations simultaneously.
Find the solution to both equations?One way to solve this system of equations is by substitution. We can solve one equation for x or y, and then substitute that expression into the other equation to eliminate one variable. Let's solve the first equation for x:
x - 5y = 3
x = 5y + 3
Now we can substitute this expression for x into the second equation:
3x - 2y = -4
3(5y + 3) - 2y = -4
15y + 9 - 2y = -4
13y = -13
y = -1
We can now substitute this value for y back into either equation to find the value of x:
x - 5y = 3
x - 5(-1) = 3
x + 5 = 3
x = -2
Therefore, the solution to the system of equations x - 5y = 3 and 3x - 2y = -4 is (-2, -1). This is the point where the solid line and dotted line intersect, as shown in the image.

In interval estimation, as the sample size becomes larger, the interval estimate.
The interval estimate becomes narrower.
An interval estimate is the use of sample data to calculate an interval of possible (or probable) values of an unknown population parameter, as opposed to a point estimate, which is a single number.
Estimation is a method of drawing conclusions about an unknown population parameter from a sample. An estimate is a statistic that is used to calculate the value of a parameter that is not defined. Intervals are statistical estimation approaches that use survey data to generate ranges of values that are likely to contain the population value of interest. Point estimates, on the other hand, are single-valued estimates of the population value. Confidence intervals are the most familiar of the various forms of statistical intervals. Certain types of analysis and scenarios, on the other hand, require the use of different scopes that provide different details.
Hence in interval estimation, as the sample size becomes larger, the interval estimate becomes narrower.

The variance of a sample or a population cannot be _____. a. zero b. calculated c. negative d. less than1
The variance of a sample or a population cannot be negative. This means that option c, negative, is the correct answer.
Variance is a statistical measure that quantifies the dispersion or spread of data points around the mean. It tells us how much the individual data points deviate from the average. The variance is always a non-negative value because it is calculated by summing the squared differences between each data point and the mean, divided by the total number of data points.
If the variance were negative, it would imply that the sum of the squared differences between each data point and the mean is less than zero. However, this is not possible because squared differences are always positive or zero.
On the other hand, options a, zero, and d, less than 1, are incorrect. The variance can be zero if all the data points in the sample or population are the same, indicating no dispersion. Additionally, the variance can be any positive value, including values less than 1.
To summarize, the variance of a sample or a population cannot be negative, making option c, negative, the correct answer.

Step-by-step explanation:

96/24 = 4
6×4 : 8×4 : 10×4
24:32:40
The length of its sides are in the ratio of 24:32:40
The longest side is the hypotenuse which is 40.
The area is base × height × 1/2 of a triangle.
32 × 24 × 1/2
768 × 1/2
=384
The area of the triangle is 384 cm squared.
Answer:
Area = 384 cm²
Step-by-step explanation:
Perimeter = 96 cm
Ratio = 6:8:10
So,
6x+8x+10x = 96
=> 24x = 96
Dividing both sides by 24
=> x = 4
So, The sides are
=> 24 cm
=> 32 cm
=> 40 cm
Now the area using Heron's Formula
Area = \(\sqrt{s(s-a)(s-b)(s-c)}\)
Where s is the semi-perimeter = 48 cm, a , b and c are the sides
Area = \(\sqrt{48(48-24)(48-32)(48-40)}\)
Area = \(\sqrt{48(24)(16)(8)}\)
Area = \(\sqrt{147,456}\)
Area = 384 cm²
