h(x)=1x-21, find h(-10)
Answer:
h(-10) = -31
Step-by-step explanation:
Substitute -10 for x in h(x)=1x-21:
h(-10) = 1(-10) - 21, or
h(-10) = -10 - 21 = -31
h(-10) = -31

Answer:
15Step-by-step explanation:
Use Pythagorean:
x² + 2.75² = 15.25²x² = 15.25² - 2.75²x² = 225x = √225x = 15Step-by-step explanation:
Perpendicular=p=2.75Hypotenuse=h=15.25we know that
[tex] \boxed{ \sf \: h {}^{2} = {p}^{2} + {b}^{2} } \\ \rm \mapsto \: {(15.25)}^{2} = {(2.75)}^{2} + {b}^{2} \\ \rm \mapsto \: {b} {}^{2} = {(15.75)}^{2} - {(2.75)}^{2} \\ \rm \mapsto \: b = \sqrt{ {(15.25)}^{2} - {(2.75)}^{2} } \\ \rm \mapsto \: b = \sqrt{232.5 - 7.5} \\ \rm \mapsto \: b = \sqrt{225.5} = 15.07=15(approx)[/tex]
Find the slope of the line through the points (-4, 3) and (3, 5)
Answer: 2/7
Step-by-step explanation:
Slope is ∆y/∆x. ∆ is read as "delta". The "delta" sign means "the difference between". So that means the difference between the y-coordinates divided by the x-coordinates gives us slope. Therefore, using the coordinates, 5-3 gives us the rise. And 3-(-4) gives us the run. Rise/Run is also equivalent to the slope. Thus, our final answer is 2/7.
4. Explain how to show that the line through points A(-2,-5) and B(-1,5) is parallel to the line that represents

y=5x−2 into polar form
Answer:
r·sin Ф = 5(r·cos Ф) - 2
Step-by-step explanation:
y = r·sin Ф and x = r·cos Ф, and so
y = 5x - 2 becomes
r·sin Ф = 5(r·cos Ф) - 2
Answer:
rsin(0) = 5rcos (0) - 2
Step-by-step explanation:
Convert y = 5x - 2 to polar coordinates.
To convert to polar apply: x = r · cos (0), y = r · sin (0)

Suppose we want to choose to letters without replacement three letters a b and c. How many ways can this be done if the order of the choices is relevant? How many ways can this be done if the order of the choices is not relevant?
Answer:
6 ;
3
Step-by-step explanation:
Letters = (a, b, c)
Number of letters to be chosen = 2
If the order is relevant, then we use permutation :
nPr = n! ÷ (n-r)!
3P2 = 3! ÷ (3-2)!
3P2 = (3 * 2 * 1) ÷ 1
3P2 = 6
If the order is not relevant ; We use combination :
nCr = n! ÷ (n-r)!r!
3C2 = 3! ÷ (3-2)!2!
3C2 = 3! ÷ 1!2!
3C2 = (3 * 2!) ÷ 2! * 1
3C2 = 3

A kangaroo hopped 3,520 yards to the lake with her baby in her pouch. She hopped the remaining 5,280 yards without her baby in her pouch. How many miles did the kangaroo hop to the lake? Miles
to determine the answer
1. add the yards hopped with the baby with the yards hopped without the baby together
3520+5280=8800 yards
2. convert yards to miles
1 yards = 0.000568182 miles

Si 1 kg de naranjas cuesta 14 pesos y al final del día el dueño de la frutería cuenta 1124 pesos por venta de naranjas, a) ¿cuántos kilogramos vendió? b) ¿cuánto cuesta comprar 3⁄4 de kg de naranjas? Si una señora compra dos naranjas cuyo peso fue de 0.3 kg, c) ¿cuánto pagó? Si en la compra de 5 kg de naranja se hace un descuento del 10%, d) ¿cuánto se paga? e) ¿Cuántos tipos de números hay en el problema?
Answer:
La respuesta a cada una de las preguntas es:
a) Se vendieron 562/7 kilogramos de naranjas.b) Comprar 3/4 de kg de naranjas cuesta 10.5 pesos.c) La señora pagó 4.2 pesos.d) Se paga 63 pesos por 5 kg de anaranja con el descuento.e) Se utilizan números racionales y números naturales.Step-by-step explanation:
a) Para calcular los kilogramos de naranjas vendidos durante el día, al tener el costo por kilogramo (14 pesos/kg) y la venta total (1124 pesos), puedes calcular de la siguiente forma:
Kilogramos vendidos = venta total / costo por kilogramoKilogramos vendidos = 1124 pesos / (14 pesos/kg)Kilogramos vendidos = 562/7 kg de naranjas.b) Para identificar el costo de 3/4 de naranja, debes multiplicar 3/4 por el valor del kg de naranja (14 pesos/kg):
Costo de 3/4 kg = (3/4 kg) * (14 pesos/kg)Costo de 3/4 kg = 10.5 pesos.c) Si la señora compra un peso total de 0.3 kg de naranja, para obtener el costo debes realizar la misma operación del ejercicio anterior, es decir, multiplicar los kilos comprados (0.3 kg) por el costo de cada kilogramo de naranja (14 pesos/kg):
Costo de 0.3 kg = 0.3 kg * (14 pesos/kg)Costo de 0.3 kg = 4.2 pesosd) Para calcular el costo de 5 kg de naranja con un descuento del 10%, debemos multiplicar el costo por kilogramo (14 pesos/kg), por el número de kilogramos comprados (5 kg), y luego por el porcentaje restante tras el descuento (90%), puesto que el total es el 100% y le restamos el 10% de descuento, nos queda el 90%:
Precio total de 5 kg de naranja tras descuento = (14 pesos/kg * 5 kg) *90%Precio total de 5 kg de naranja tras descuento = 70 pesos * 90%Precio total de 5 kg de naranja tras descuento = 63 pesos.e) De entre todos los tipos de números que hay, dentro de los ejercicios resueltos se hace uso de los números racionales (por el uso de fraccionarios) y de los números naturales (por el uso de los números enteros positivos).

Answers:
a = 7b = 14c = 7d = 7*sqrt(3)======================================================
Explanation:
The smaller triangle on the left is a 45-45-90 triangle. In these triangles, the hypotenuse is sqrt(2) times that of the leg length.
The hypotenuse shown is 7*sqrt(2), so that must mean each leg is 7 units long. Therefore, a = c = 7.
The triangle on the right is a 30-60-90 triangle. The shorter leg (opposite the smallest angle of 30 degrees) doubles to get the hypotenuse. So we can say b = 2a = 2*7 = 14. The longer leg is exactly sqrt(3) times that of the shorter leg. The longer leg is d = a*sqrt(3) = 7*sqrt(3)

Eliana is using a magnifying glass. The lens of the magnifying glass has a radius of 4 centimeters. What is the lens's area? Use 3.14 for pi.
Answer:
[tex]area = \pi {r}^{2} \\ = 3.14 \times {(4)}^{2} \\ = 50.24 \: {cm}^{2} [/tex]
The Area of the lens is equal to 50.24 cm²
What is the area and circumference of a circle?The circumference (or) perimeter of a circle = 2πr units. The area of a circle = πr2 square units. Where r is the radius of the circle. The circumference of the circle or the perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of the circle defines the region occupied by the circle.
Given here: Elliana is using a magnifying glass and radius of the magnifying glass has radius of 4 cm.
The formula for the area of a circle is A = πr², where r is the radius of the circle. The unit of area is the square unit, for example, m², cm², in², etc.
Thus Area of the lens of the glass is equal to A=πr²
=3.14×4²
=50.24 cm²
Therefore the len's Area is 50.24 cm²
Hence, The Area of the lens is equal to 50.24 cm²

hey can someone tell me why 132 is wrong? and help me with the right answer pls
Answer:
∠CBA = 132
Step-by-step explanation:
Bisectors split up an angle into two identical angles
Thus, 7x - 11 = 2x + 44
This is the equation we will use to solve for x
7x - 11 = 2x + 44
step 1 add 44 to each side
44 + 11 = 55
-11 + 11 cancels out
we now have 7x = 2x + 55
step 2 subtract 2x from each side
7x - 2x = 5x
2x - 2x cancels out
we now have 5x = 55
step 3 divide each side by 5
5x / 5 = x
55 / 5 = 11
we're left with x = 11
The question is asking for the measure of ∠CBA
To find the measure of ∠CBA we plug in 11 for x in one of the given expressions and multiply that by 2 ( this is because the two angles are identical so there is no need to find the measures of both because ∠CBD≅∠ABD )
7(11) - 11
7 * 11 = 77
77 - 11 = 66
66 * 2 = 132
1.Construct or draw an isosceles triangle with one angle measure of 70 degrees. Label all of the angle measures.
Answer:
See images
Step-by-step explanation:
Either one should work.
An isosceles triangle is a triangle where two angles are the same & the third angle is the supplement of their sum.
If you wanted the matching angles to be 70 & 70, your final angle would be 40 because:
70 + 70 = 140
180 - 140 = 40
If you wanted the supplement angle to be 70, your matching angles would be 55 & 55 because:
180 - 70 = 110
110 / 2 = 55
Hope this helped. :)
